1955 Revolution: Aftermath

The people of Bahía Blanca take to the streets to celebrate the triumph of the Revolution.

Aftermath



Joy and happiness in the crowd after Perón resignation

Thus concluded the first Argentine armed conflict of the 20th century, which, in just seven days of fighting, claimed the lives of nearly a thousand people. The casualties included civilians and soldiers—men, women, children, and the elderly. The majority of the deaths occurred on June 16 during the bombing of Buenos Aires, when 229 victims were identified in hospitals, clinics, and public aid facilities. However, the true death toll was far higher, as Dr. Francisco Barbagallo notes in Daniel Cichero's Bombs Over Buenos Aires. The chaos was so overwhelming that tracking the countless bodies transported by ambulances and trucks became impossible.

To grasp the scale of the attack, it is worth noting that 14,000 kilograms (14 tons) of explosives were dropped that day—half the amount used in the bombing of Guernica—yet the death toll was nearly equivalent to that of the Spanish city.

On that day, 43 rebel aircraft carried out the assault: twenty North American AT-6s, five Beechcraft AT-11s, three Catalinas, one Fiat G-55A Centauro reconnaissance aircraft dispatched to Rosario to contact General Bengoa, and ten rebel Gloster Meteors. Additionally, four aircraft initially refused to counter the attack but later joined the rebellion. Including loyalist aircraft, the total number of planes involved exceeded fifty.


Celebrations in Bahía Blanca

On June 16, 1955, the Air Force and Naval Aviation took their first baptisms of fire; the first two shoot-downs in the national aeronautical history occurred when the AT-6s of midshipmen Arnaldo Román and Eduardo Bisso were hit by the enemy, the first by shrapnel from the Gloster Meteor of Lieutenant Ernesto Adradas over the Río de la Plata and the second by anti-aircraft guns from the 3rd Regiment of La Tablada in the town of Tristán Suárez, Buenos Aires, not counting the Gloster that, due to lack of fuel, crashed into the waters of the Plata, between Carmelo and Colonia. That day also saw the first shoot-down carried out by a jet on the American continent (that of midshipman Romás by Lieutenant Adradas) and the entry into action of the tanks when a Sherman of the Motorized Regiment “Buenos Aires” fired on the Ministry of the Navy.

Buenos Aires became the first (and so far, only) capital in South America to endure a large-scale aerial bombardment, joining the ranks of only a few cities worldwide to have suffered such an attack. It shares this tragic distinction with Gibara in Cuba, bombed by President Machado's air force in 1931, and Puerto Casado in Paraguay, targeted by the Bolivian Air Force in 1933. However, both of these events pale in comparison to the scale of the bombardment in Buenos Aires.

During the attacks, numerous locations in the city were hit, with the main targets including the Government House, Plaza de Mayo, the National Mortgage Bank, the Ministry of Finance, the Army Ministry (Libertador Building), Hotel Mayo, the Central Police Department, the CGT headquarters, the Ministry of Public Works, the Patagonia Import and Export Company, various buildings along Av. Paseo Colón, the service station of the Argentine Automobile Club, and the presidential residence at Unzué Palace.

Additionally, La Tablada suffered heavy damage as the 3rd Infantry Regiment was strafed and bombed on Av. Crovara and Av. San Martín while marching toward the city center. The Ministry of the Navy was also struck during an attack by Army units, and the Banco Nación was hit as revolutionary civilian commandos took refuge on its rooftop.

On September 16, Argentina witnessed its first air-naval battle when the Peronist Air Force engaged the Ríos Squadron. Mar del Plata was also bombed, initially by a lone naval aircraft and later by Navy ships targeting large coastal oil deposits, the Submarine Base, Army positions on a nearby golf course, and the Camet Anti-Aircraft Artillery Regiment.

Three days later, the submarine Santiago del Estero entered combat for the first time, using its 40 mm Bofors cannon to fire on unidentified aircraft near Montevideo. The towns of Saavedra and Río Colorado also fell victim to aerial bombardments during this period.

In that revolution, the greatness and miseries of war were fully exposed: acts of heroism and resolve, reckless actions, brutal deeds, weaknesses, and betrayals.

On June 16, it became evident that a significant portion of the population was willing to fight for Perón to the death. That day, thousands of workers took to the streets to arm themselves and fight for their leader. Dozens died in combat, most during the attack on the Ministry of the Navy. Similarly, on September 21, an unidentified number of fervent members of the Alianza Libertadora Nacionalista perished during revolutionary troops' assault on their headquarters.

There were soldiers who fulfilled their mission according to the training they had received, such as the much-criticized Lieutenant Adradas, who simply did his duty, or Vice-Commodore Síster, steadfast in his determination to defend the Peronist regime. Others failed to rise to the occasion. Some military figures upheld their honor, like Admiral Benjamín Gargiulo, who, like ancient Roman generals, chose to take his own life rather than face disgrace. There were officers willing to die rather than surrender, including General Lonardi, Colonel Arturo Ossorio Arana, Captains Perren and Rial, Commodore Krausse, Majors Montiel Forzano and Juan Francisco Guevara, Colonel Arias Duval, Captain Ramón Eduardo Molina, and the somewhat reckless Dalmiro Videla Balaguer, all on the rebel side. Others fell in combat, such as Brigadier General Tomás Vergara Ruzo and numerous aviators, soldiers, and sailors who fought valiantly on both sides.

On the loyalist side, the resolve and professionalism of generals like Franklin Lucero, Miguel Ángel Iñíguez, and José María Sosa Molina, Lieutenant Colonel César Camilo Arrechea, Captain Hugo Crexell, and many others stood out, honoring their respective branches of service. The Argentine honor also shone aboard the destroyers La Rioja and Cervantes, and in the steadfastness of the personnel in Bahía Blanca and Punta Alta, who held firm in their posts against powerful advancing forces.

However, there were also ambiguous and wavering actions, such as those of Admiral Olivieri, Generals Bengoa, Lagos, and even Aramburu. Lieutenant Colonel Barto displayed indecision and despair during the regiments’ advance toward southern Buenos Aires. Similarly, First Lieutenant Rogelio Balado, one of the regime’s iconic pilots, switched sides and, during combat, refused to fire on an enemy Avro Lincoln that had just strafed loyalist positions at the Pajas Blancas airfield. Captain Bernardo Benesch did the same when ordered to attack targets in Mar del Plata on June 19. (Before setting sail, he had offered dissenting officers and sailors the opportunity to leave the ship and return to shore, though he himself did not follow through.) Captain Edgardo Andrew also hesitated, asking Captain Rial to revoke the order to bomb the 5th Infantry Regiment in Bahía Blanca, which was refusing to surrender.

During the second phase of the revolution, over 70 combat and patrol sorties were conducted, and the main regiments and military units from Buenos Aires, Córdoba, Mendoza, San Luis, and Patagonia were mobilized.

On September 21, 1955, as the final acts of the conflict concluded, an atmosphere of anticipation lingered across the country. While government emissaries and representatives of the rebel forces engaged in negotiations, combat units in Córdoba began their gradual return to base.

That same day, news of the revolutionary forces’ victory spread, prompting the people of Córdoba to flood the streets in celebration of the regime’s fall. Crowds gathered at Plaza San Martín, in front of the ruined Cabildo building, adorned with three Argentine flags, cheering for the leading figures of the rebellion. Thousands of men and women entered the adjacent Cathedral to give thanks to the Lord and the Holy Mother for the end of the conflict. Meanwhile, a jubilant procession of cars, motorcycles, trucks, buses, and pedestrians filled the streets, chanting in support of the revolution, its leaders, and the nation’s heroes.

Two days earlier, Bahía Blanca had erupted in similar enthusiasm. Residents filled the streets, cheering, singing, and waving flags while wearing sky-blue and white ribbons and rosettes. Portraits of San Martín, Belgrano, and Our Lord Jesus Christ were prominently displayed. Outside the CGT building, crowds sang the National Anthem, symbolizing the defiance of the fallen regime, and applauded Admirals Toranzo Calderón and Olivieri as they arrived at Bahía Blanca’s municipal headquarters after their release from detention in La Pampa. In front of the burned-out offices of the Democracia newspaper and the Bernardino Rivadavia Public Library, the crowd shouted, “Death to Perón!” and “Long live the Fatherland and Liberty!”

On September 21, back in their respective units and after a refreshing hot bath, cadets and conscripts from the Military Aviation and Airborne Troops schools in Córdoba were informed that the next day they were going to participate in the parades that had been held to commemorate the victory.
On the 22nd, very early in the morning, the soldiers formed up in the courtyards of both schools to head into the city to parade with the Army troops and civilian commandos who had taken part in the battle. The Cadet's Diary is graphic in recounting the events.

"The unit remains in the same condition as always... All the officers gathered with General Lonardi at the Cadet Casino, which is why we couldn’t contact F... to request a replacement. When we finally managed to, he told us there was only one tent left with a cadet and 16 soldiers. We worked like mad to take down the tents and move them to the Squadron. Once we finished everything, we went to the unit, and there, among the three group leaders, the 'exciting' draw took place to decide who would stay... If it had been me, I would have had to muster a great deal of willpower to remain, but luck was on my side; of course, it fell to the 'Turk.' Poor guy, he won’t be any better off than I am."

Thus, the troops boarded military trucks and buses and headed toward the provincial capital where, upon reaching Av. Vélez Sarsfield, they dismounted to begin the parade. They did so after a long wait, in front of the population who cheered them and threw flowers at them while a shower of papers fell from nearby buildings to the cry of “Freedom! Freedom!” which could be heard everywhere.
After the parade, the troops returned to the barracks to continue their activities during peacetime, unaware that the following day would claim the life of another comrade.
During a patrol and observation flight, the Calquin I.Ae-24 of the 2nd Attack Group, piloted by Second Lieutenant Edgardo Tercillo Panizza, crashed on the outskirts of the city due to mechanical problems.


Officers welcome their boss after his release

Once they had heard of this, cadets and officers headed towards the site, first crossing the Aeronautical District, with the intention of seeing the remains of the aircraft that was still smoking on the field. Once there, they came across the remains, observing them in silence while meditating on the events that had taken place in the previous days and the course that history would take from that moment on.
Mar del Plata also joined in the celebrations with long human columns parading through its streets to the City Hall, to sing the National Anthem and wave flags.
On September 23, the fronts of the city woke up decorated with the colors blue and white; around 10:00 there was a new march to the government palace where rosettes, ribbons and flowers were distributed as in the days of May and the celebrations continued in different places until late at night.
Argentina was beginning a new path; An era had ended and another had begun, but the disagreement between brothers was not going to end there. The country would never find its way again and society would continue to crumble to unsuspected limits.

Malvinas: The Counter Attack of the "3 de Oro" at Wireless Ridge

The Counterattack of the "3 de Oro" (Golden 3) (Part 1)

By Lt. Col. (R) (Malvinas War Veteran) Víctor Hugo Rodríguez

The author served in the Malvinas as a First Lieutenant, Chief of the 1st Section of Company "A" of the 3rd Mechanized Infantry Regiment "Gral. Belgrano," nicknamed "3 de Oro" (Golden 3) during the Triple Alliance War, due to the yellow breastplate that adorned their blue jackets.





June 13, 1982, 22:00 hours — Tumbledown Hill, overlooking Moody Brook Valley. To the left was Longdon; in front, the 7th Infantry Regiment of La Plata was enduring relentless fire for two days, June 11th and 12th. It was hell. Positioned 100 meters above them and 5 kilometers away, we witnessed how the British enemy left no centimeter unscathed by naval, artillery, and mortar fire. It was clear they were preparing an assault on the regiment's heights. Occasionally, they turned their attention to us, a forewarning of their advance towards Tumbledown.

Below Longdon, Captain Soloaga—a war hero who carried his Sanmartinian values into peace—"clung like an oyster" to the rocks. His men were already fighting, enduring an infernal bombardment day and night. From our vantage point, we watched, both awestruck and helpless, as their resilience unfolded. Occasionally, patrols emerged—but only to retrieve their fallen and place them in an abandoned ambulance stuck in the valley's mud before returning to combat. Watching them march back into that artillery barrage was profoundly moving.
At 22:00 hours on June 13th, Captain Zunino, commander of Company A "Tacuarí" of the "3 de Oro," summoned us. A remarkable officer for wartime, Zunino convened 2nd Lt. Dobrovevic (support group leader), 2nd Lt. Mones Ruiz (2nd rifle section), Sub-Lt. Aristegui (3rd section leader), and me (1st section leader).

“We need to support the 7th Regiment, which is under attack on those heights,” he said.”. 

We knew the terrain only by sight—no reconnaissance had been done. The day before, we had deployed to Tumbledown, abandoning previous positions. Defending our spot against the expected assault the next day was our sole focus. Our positions consisted of low rocks; our aluminum screw-shovel “Tempex” tools had broken within a week, unable to withstand the greda soil. Digging foxholes was impossible. Equipment? Just a blanket, a shared tent cloth, and only five magazines per soldier. Night vision? Only the captain had one. Radios? None. Batteries were dead, leaving us with no communication within or outside the company. To supplement ammo, I ordered rounds carried in socks tied around our necks.



Aristegui, a 4th-year cadet serving as a "commissioned sub-lieutenant" in the Malvinas, was barely older than his soldiers. Yet, he was an example of leadership. I said,

“Aristegui, form up. You take the right, and I'll take the left. Let's cross the valley quickly and head for the heights.”. 

The battlefield was chaos—roaring, blazing, hellish. Longdon, the valley, Wireless Ridge where the 7th Regiment was positioned, Port Argentino, Mount Williams—all were alight with tracer rounds and rocket fire. It was full-on war, the final assault. We waded through a freezing brook, soaked to the waist. Snow fell. The cold? I can’t remember. The adrenaline heated our bodies.

From the valley, we realized the heights, where the 7th Regiment was supposed to meet us, were instead occupied by British forces, firing rifles and rockets at the abandoned Royal Marines barracks. Without communication, we had to resolve it on our own. I turned to Aristegui:

“The enemy’s up there. Let’s surprise them. Don’t advance straight—move to the right, gain the height advantage.”

Moments later, I heard, 

“The sub-lieutenant’s been hit in the neck!” 

I ran to him, blood pouring from his neck, when one of his men, slapping his cheek, shouted:

"You’ve been good to us, kid. We’ll get you out of here."

They carried him back to safety. Today, Aristegui, nicknamed “Nono,” is an exemplary Malvinas officer, earning the respect of his soldiers at just 19 years old. The bullet had pierced his neck, narrowly missing his spine..

Still in the valley, the enemy illuminated us with flares. Forty of Aristegui’s men and forty of mine were exposed. Knowing artillery fire was imminent, I ordered an assault on their positions, 100 meters above us on Wireless Ridge’s heights. Seconds later, an artillery barrage rained down where we had stood moments earlier. The shells exploded 50 meters overhead, showering us with lethal fragments.

“Charge!” I yelled. There was no other option to reach the heights and support the 7th Regiment. What a sight—my soldiers and Aristegui’s, running uphill, driven by sheer determination. “Cata” Carballo, my speedy aide; “Mono” Paz, my radioman without a radio; Aumasane, Izaguirre, “Bombón” Díaz, Juan Fernández—young men from Buenos Aires, cold, hungry, yet filled with love for their country, surging from the valley to claim that piece of Malvinas soil.

They were just 18 years old. They had little food, no communications, yet an unyielding spirit. To think the tabloids later dismissed them as mere “boys of war”...

Malvinas: The Mistake of Marching in Broad Daylight

The Error of Errors

In the photo, commandos of the 601 operating in the San Carlos area in broad daylight.

Excerpt taken from the book "Comandos en Malvinas - La otra historia," chapter "Analysis of Operations." The book is available in print and e-book format on Amazon.

We have all read countless times that the great mistake made by the Argentine commandos at Top Malo was entering the house to spend the night. But what would have happened if no one had seen them enter?

...However, if the commandos of the 602 Company committed a mistake worthy of going down in history — one that stands out above all others — it was their decision to start marching immediately after being dropped off by helicopters, in broad daylight, no less. Once on the ground, the grave mistake of flying in during the morning was already irreparable, but to immediately begin moving toward the summit of Mount Simon was, without a doubt, an almost suicidal act. It was certainly a reckless move, and it makes it abundantly clear that these men had no idea what they were doing.

The terrain of the Malvinas, consisting primarily of hills and vegetationless plains, facilitated long-distance observation. This allowed British observers, hidden in advantageous positions within their observation posts (OPs) and equipped with telescopes, to monitor the terrain for many kilometers around them.

Once on the ground, an alternative course of action that Vercesi could have chosen, as a lesser evil, would have been to remain motionless. The men could have hidden as best they could, waiting for nightfall, hoping their infiltration had gone unnoticed or trusting that, if they had been detected, the British would not have time to react.

But moving during daylight? On terrain like the Malvinas? And, on top of that, climbing a height? It was a completely irrational decision that true commandos would never have made, especially in a situation where British dominance was already well established.

But one didn’t need to be a commando to know that. A simple conscript soldier doing his military service, if he had paid attention to his theoretical lessons, would know that you don’t do that. One doesn’t even need to be a soldier. It’s just common sense. An eight-year-old child who regularly plays hide-and-seek would understand that if you don’t want to be seen in an open, well-lit area, you simply don’t move.

To a British observer hidden among the rocks of a hill, scanning the terrain intently, a man loaded with equipment moving across the Malvinas peat bogs, no matter what camouflage he wore, would stand out like a black dot against the predominantly soft hues of the peatlands.

If the distance was too great, the observer wasn’t paying attention, or he was already tired, there was a slim chance the man might not be detected. But if that one man carrying equipment is accompanied by twelve more, and, on top of that, they are made to ascend a mountain or hill — or descend from it — and, to make it even worse, do so over snow, as they did on the 30th, then the march of the commandos of the 1st Section of the 602 became something akin to lighting a match in a dark room. It was as if they were shouting, “Hey guuuuys, we’re heeere!”

This reckless practice was common among the patrols of the GOE, the 601, the 602, the APCA, and the APBT.

Beagle Crisis: Argentine Intelligence Tames Pinochet

The Art of Taming: When Argentina Took the SK-105s from Chile

Esteban McLaren for FDRA

Imagine you have a serious problem with a neighbor. You buy a rifle for self-defense. Then, you find out your neighbor plans to buy a shotgun for the same purpose. You take advantage of this information, outbid them, and end up with the shotgun too. Now your neighbor is doubly disadvantaged: not only do they lack a weapon, but they've helped you double your arsenal. This is exactly how Argentina turned the provision of armored defense in Southern Patagonia into a zero-sum game: what Chile lost, Argentina gained. A historic taming!

The intelligence operation to re-acquire the Steyr SK-105 Kürassier light tanks is one of the most intriguing stories in South American military intelligence, involving Argentina and Chile during a period of heightened bilateral tension. The Steyr SK-105 Kürassiers obtained by the Argentine Army in the early 1980s originally came from a batch built for Chile. In 1981, these tanks quickly arrived at armored units in Patagonia, a high-tension region. To secure these vehicles, Argentine authorities had to pay a premium, which not only immediately bolstered their armored capabilities but also prevented Chile’s military modernization. Although costly, the maneuver placed Argentina in a position of clear mechanized superiority.

Historical Context

In the 1970s, relations between Argentina and Chile were extremely tense, partly due to territorial disputes like the Beagle Channel conflict. By 1978, the situation had escalated to the brink of armed conflict. In this context, both countries began strengthening their military capabilities.

It sounds like a geopolitical and military nightmare—a scenario where meticulous planning is thwarted by factors beyond experts’ control. Imagine those Chilean technicians, analyzing every detail of southern Chile’s rugged terrain—with its steep mountains, rivers, channels, and difficult roads—carefully selecting a light tank that seemed to meet all their needs, only to find their acquisition blocked by a last-minute strategic move. This adds an emotional and historical layer of complexity to the story.

"the tanks we ordered and had manufactured for us ended up on the other side of the border"

This kind of situation represents not only a technical defeat but also a moral one, as those tanks—designed to tackle similar challenges in rugged terrain—are now in the hands of a neighboring nation with whom there are historical tensions. It also reflects the geopolitical dynamics of the region, where arms purchases depend not only on technical capabilities but also on international alliances and rivalries.

The irony that all that technical and logistical effort ended up indirectly benefiting the "enemy" would be devastating for those involved. Moreover, it highlights the fragility of national security when relying on external suppliers for defense equipment and how an unexpected shift can significantly alter the balance of power in a volatile region like the Southern Cone of South America.

On the other hand, it underscores the importance of diplomacy and intelligence in military acquisitions, where not only the equipment’s capabilities are evaluated but also the reliability of trade partners and the potential geopolitical consequences of such acquisitions.

Chile's decision to acquire the Austrian SK-105 Kürassier light tank in the 1980s was shaped by a complex geopolitical and military context, influenced by various constraints and the country's specific operational needs.

A context of restrictions and sanctions

During the 1970s and 80s, Chile, under Augusto Pinochet's dictatorship, faced significant international restrictions on arms purchases, largely due to sanctions imposed by various Western countries and the UN in response to the regime’s human rights violations. These restrictions limited Chile’s options for acquiring military equipment from countries with whom it had traditionally maintained defense trade relations, such as the United States and certain European nations. For example:

1. United States: The U.S. imposed an arms embargo on Chile following the 1973 coup, which prevented Chile from acquiring American-made military equipment.
2. United Kingdom: While there were some sales to Chile, tensions and restrictions persisted due to internal policy and international pressure.
3. Another European Countries: Several European countries also adopted restrictive policies on arms sales to Chile due to sanctions over human rights violations, with Austria eventually adhering to these restrictions under strong internal pressure.

Austria's Choice and the SK-105 Kürassier

In this context, Austria emerged as a viable option for Chile, as it was not aligned with the power blocs imposing sanctions. Being a neutral country and not part of NATO, Austria faced no significant political restrictions on arms sales to Chile at that time. Additionally, Austria’s defense industry was seeking to expand its markets, and the SK-105 Kürassier presented an opportunity for them.

Features of the SK-105 and Its Suitability for Chile's Needs

The SK-105 Kürassier was designed by Austria as a light tank intended for territorial defense, particularly suited for mountainous and rugged terrain, aligning well with Chile’s geographic needs, given its extensive mountainous regions along the Andes.

While similar to the AMX-13, the SK-105 Kürassier is 4 tons heavier, with a ground pressure of 0.78 kg/cm². It has a larger chassis than the French tank and is equipped with a more powerful, 320 HP water-cooled engine. The transmission is manual, featuring six forward gears and one reverse, enabling a maximum road speed of 70 km/h.

The suspension system includes five pairs of road wheels, three support rollers, and two sprockets: one tensioning and one drive. The first road wheel has a shock absorber and spring to enhance suspension.

The vehicle has an internal fuel tank of 350 liters, providing a range of 520 km on paved roads. Its main 105 mm gun, the same used on the AMX-13 105 version, can penetrate up to 360 mm of armor and is mounted on an oscillating turret.

Among the features that made the SK-105 appealing to Chile are:

• Mobility in Mountainous Terrain: With a light weight of around 17 tons and an ability to operate on difficult terrain, the SK-105 was ideal for Chile’s mountainous regions. Specifically designed for rugged landscapes, it had enhanced climbing capabilities compared to heavier combat tanks.
• Armament: Equipped with a 105 mm cannon, the SK-105 provided substantial firepower for a light tank, suitable for countering armored threats within the South American context.
• Oscillating Turret: The gun’s oscillating turret allowed for steeper firing angles than a traditional turret. This feature offered three main advantages: a high gun position that maintained weapon depression capability, a low profile enhancing battlefield concealment, and an automatic loader increasing rate of fire. However, in practice, the loader’s performance was limited. Additionally, the main gun experienced reduced recoil, thanks to the increased mass that helped dissipate energy—an advantage particularly useful in mountainous terrain.
  
• Cost and Maintenance: Compared to heavier tanks, the SK-105 was more economical to operate and maintain, making it a practical logistical and financial choice for Chile.

 

Operation Development

In the annals of military history, few operations have been as laden with intrigue and controversy as the one involving Chile, Austria, and ultimately, Argentina. This story, worthy of a cinematic thriller, begins with an ambitious order: Chile commissioned Austrian company Steyr to supply 100 SK-105 Kürassier tank destroyers, six recovery tanks, three Saurer infantry fighting vehicles, three command infantry fighting vehicles, 360 submachine guns, and 124 machine guns. The entire order totaled approximately 2.075 billion Austrian schillings, or around $148.1 million in 1978, equivalent to about $721 million in 2024 (Pilz, 1982, pp. 125-127).

Chile, amid its military dictatorship, was on the verge of receiving these Steyr SK-105 Kürassier tanks when an unexpected twist changed the course of history. Under overwhelming political pressure, the Austrian government canceled the shipment. From the outset, the order had been a source of intense controversy. In democratic Austria, selling arms to a regime accused of systematic human rights violations was unthinkable. Chilean exiles and left-wing political movements mobilized to demand that the Austrian government block the export, even though the vehicles were ready for dispatch (Kabl, 2022).

Moral justifications became the centerpiece of the protests: how could Austria, a country committed to human rights, sell arms to a dictator like Pinochet, infamous for repression and extrajudicial executions? Additionally, Austria faced a reputation dilemma for breaking such a significant contract, though some argued this impact might be "mitigated" by the availability of similar vehicles, like the French AMX-13, on other markets. There was also an attempt to secure Chile's agreement to a purchase condition: the tanks were only to be used for defense against external threats, not for internal repression—a condition difficult to enforce. Nevertheless, the shipment was canceled, and the tanks were sent to storage, sparking further controversy in Austria due to the economic losses and potential job cuts resulting from the decision.

Amid this scandal, Argentine military intelligence, always alert to new opportunities, saw a chance to turn Chile’s setback into Argentina’s gain. With the finesse of a spy thriller, Argentine intelligence orchestrated a plan to redirect the tanks to their own country. On June 15, 1981, the New York Times (click here) revealed the audacious maneuver: Argentina had purchased the Austrian vehicles at a premium, paying $32 million above Chile’s original order. The news made global waves.

Drama unfolded during the operation’s final phase. Protesters gathered at the Steyr-Werks factory, where the tanks were built, intent on blocking their shipment to Argentina. But tensions escalated violently as factory workers, furious over the potential job losses, clashed with the demonstrators, leaving 60 injured and clearing the way for the tanks to depart.

The story ended on an ironic note: the following year, Steyr, previously in a precarious financial position, moved from deficit to surplus, thanks largely to this deal. What began as a moral dispute in Austria concluded with an unexpected economic boon, reminding the world that in the complex zero-sum game of politics and war, there are always winners and losers.

In the world of diplomacy and arms sales, nothing is as it seems, and Argentina’s maneuver to redirect tanks intended for Chile is a perfect example of intrigue and corruption. It’s almost certain that Argentina’s plan involved bribes to key officials and figures in the tank delivery process. It’s worth noting that the entire arms sales process in Austria was deeply politicized—a fertile ground for under-the-table deals.

Through a clever intermediary, Argentina offered Austria a higher price than Chile’s original agreement. Thus, the tanks initially destined for Santiago ended up in Buenos Aires. But this raises an uncomfortable question: why did Austria prohibit the sale to Pinochet’s regime but not apply the same standard to Argentina’s military junta? The answer remains elusive, though Steyr’s financial troubles, which threatened the company with bankruptcy, likely played a significant role in permitting this second deal. Without Argentina’s offer, the tanks would have remained in storage, incurring costs and serving as a reminder of a bad decision. Argentina’s proposal gave Vienna a second chance to treat the matter as business rather than a principled stand.

Why was the sale to Argentina accepted? First, despite similar human rights abuses, Austria’s diplomatic relationship with Argentina was different. Austria viewed Argentina as a strategic market in South America, and the decision to sell the Kürassiers was partially influenced by economic interests and trade relations. Secondly, although Argentina was also under a military dictatorship, international scrutiny over its human rights record—while condemned—didn’t reach the same intensity in some European circles as Chile’s. This allowed the sale to be justified differently to the international community.

The story’s conclusion took place in 1981, when the first 57 Austrian SK-105 Kürassier tank destroyers were loaded onto an Argentine ship at the French port of Le Havre, bound for Argentina as part of a larger 120-unit order. By November 1982, the remaining 27 tank destroyers completed the shipment. However, Argentina and Steyr’s relationship didn’t end there; in 1985, ten additional recovery vehicles were sent, followed by four more SK-105s in 2006.

Today, these tanks are in service with the 11th Armored Cavalry Reconnaissance Squadron “Colonel Juan Pascual Pringles,” headquartered in Rospentek Aike, and the 11th Tank Cavalry Regiment based in Puerto Santa Cruz. Interestingly, Rospentek Aike is located just a few kilometers from the Chilean border—a silent reminder of the tensions that once fueled this complex dance of power and deception.

It's important to note that the operation involved not only intelligence work and potential bribery but also a disinformation tactic to ensure that Chilean authorities remained unaware of what was happening until it was too late. Chile learned through the New York Times article that "its" tanks had been redirected across the border to Argentina, forcing them to seek an alternative solution to reinforce their military capacity amidst escalating tensions with their neighbor.

Thus, what began as a straightforward commercial transaction evolved into a masterwork of international intrigue, where a company’s financial need met a nation’s military ambition. In this zero-sum game, Argentina emerged victorious, leaving Chile empty-handed and Austria with a heavy conscience—but a full treasury.

Impact and Repercussions

The operation had a significant impact on diplomatic and military relations between Argentina and Chile. While it did not trigger open conflict—primarily because Chile would have been unable to withstand a confrontation in the Southern Theater with such a military imbalance—it deepened mutual distrust and highlighted the underlying tensions of an era marked by military dictatorships and regional rivalries.

From a military perspective, Argentina successfully strengthened its tank fleet at a critical moment, albeit at a considerable cost due to the premium paid and the risks involved in the operation. Chile, meanwhile, was forced to reevaluate its arms acquisition strategies and the security of its international operations.

Reasons Why This Case Is Fascinating

This story is fascinating by various reasons:

1. Strategic Maneuvering: The operation is a textbook example of strategic maneuvering in international relations, where Argentina leveraged intelligence, diplomacy, and financial incentives to outmaneuver Chile.

2. Espionage and Disinformation: The case involved not only intelligence but also deliberate disinformation to keep Chile in the dark, creating a sense of suspense and intrigue akin to a spy thriller.

3. Moral and Political Complexity: Austria faced a moral and political dilemma—balancing economic gain against ethical concerns in dealing with military regimes—highlighting the complexities of arms sales in volatile regions.

4. Economic Motivation Meets Military Ambition: The intersection of Steyr’s financial needs and Argentina’s military ambitions turned a simple arms sale into a high-stakes game with regional repercussions.

5. Regional Power Dynamics: This case exemplifies the zero-sum nature of regional power dynamics in South America, where one country's gain directly impacted its neighbor's security and defense strategies.

6. Long-lasting Symbolism: The tanks’ final placement near the Chilean border serves as a lasting reminder of the geopolitical tensions and maneuvering between the two countries during this era.

In summary, the operation to re-acquire the Steyr SK-105 Kürassier tanks is a prime example of the complex and often murky interplay between espionage, diplomacy, and military strategy in South America during the Cold War. It’s a story that highlights how countries may resort to extraordinary methods to secure a strategic advantage in high-tension situations.

Argentina: On How the 1955 Revolution Shaped Military Thought

Under the Aegis of Aries

By Esteban McLaren

During World War II, as in World War I, Argentina maintained an official stance of neutrality for much of the conflict. However, within the armed forces—particularly in the Army—tensions emerged among factions debating what the country’s true position should be. One such faction, aligned with the Grupo de Oficiales Unidos (United Officers Group - GOU), sympathized with the Nazi regime and, until 1943, advocated for Argentina to join the war on the side of the Axis powers. Following their successful coup d'état that same year, this faction seized control of the government, laying the groundwork for their preferred candidate, Juan Domingo Perón, to ascend to the presidency in the 1946 elections.

Perón, the son of Italian immigrants, initially assumed office as a constitutional president. However, he soon implemented a series of reforms aimed at suppressing opposition and consolidating his grip on power. Leveraging the surplus funds accumulated during Argentina’s wartime trade boom, he garnered support through bribes, subsidies, and other corrupt practices that allowed him to manipulate institutions to his advantage. Mismanagement of public resources became rampant: individuals with no prior wealth amassed fortunes, opposition media outlets were shut down or co-opted, and dissenting voices were systematically silenced—some through torture.

Amid this climate, a marginalized faction of the armed forces, sympathetic to the Allies and sidelined since the 1943 coup, began to regroup. This paper seeks to examine the recurring patterns within the anti-Peronist, or constitutionalist, forces that influenced Argentina's internal political-military dynamics, particularly during the period from 1955 to 1988, when these factions played a pivotal role in shaping the nation’s political landscape.

The Pro-Allied Faction

The earliest manifestations of this faction within the Argentine Army likely became evident during the failed coup attempt of 1951. What defined this group was their unwavering focus on action. These were military professionals trained to view challenges through the lens of the friend-enemy dichotomy. Their approach to any threat was inherently military: once the threat was identified, the enemy was delineated, and operations were executed to attack, pursue, and, if possible, annihilate it.

A prominent example of this ethos is Admiral Benjamín Gargiulo, the founder of the Argentine Navy's Marine Infantry Corps (IMARA). Inspired by the U.S. Marine Corps, Gargiulo instilled a spirit of rigorous preparation and combat readiness in his troops. During the failed coup of June 16, 1955, when his efforts were thwarted, Gargiulo chose to commit suicide—an act that shocked many but epitomized his sense of military honor and courage. This same valor would be echoed 27 years later at the Battle of Mount Tumbledown, where the Marine Infantry displayed exceptional bravery in the defense of Puerto Argentino during the Malvinas War.

This decisive and action-oriented approach stood in stark contrast to the hesitation shown by Juan Domingo Perón during the Liberating Revolution of 1955 (or 1955 Revolution). Faced with a rebellion in which only 18% of the troops turned against him, Perón faltered. The insurgents, led by General Eduardo Lonardi, stood firm, refusing to negotiate or compromise. Perón, accustomed to the political arena where deals and compromises were standard, seemingly misjudged the rebels’ intentions. Believing they sought a power-sharing agreement, he hesitated to order a decisive assault against their encircled forces. This hesitation allowed the insurgents to regroup and resume their offensive.

Once Lonardi's forces had reorganized, his first act was to order Perón’s arrest. This move, naturally, opened the door to his trial and potentially his execution—bringing Perón’s government to an abrupt end. Only then did Perón fully realize he was facing seasoned military professionals, not the political opportunists he was accustomed to outmaneuvering. His miscalculation sealed his fate, underscoring the stark difference between a military trained for decisive action and a politician unprepared for the harsh realities of armed rebellion.

The Liberating Revolution and the Formation of Army Officers

The Liberating Revolution, which overthrew the government of Juan Domingo Perón in 1955, had a profound impact on the composition and professional trajectory of officers within the Argentine Army. This process began with mass purges of officers deemed loyal to Peronism and the reinstatement of those aligned with anti-Peronist forces. Spearheaded by the Revolución Libertadora between 1955 and 1956, these changes disrupted the Army’s hierarchy, significantly altering its command structure and deeply affecting the careers of numerous officers (Mazzei, 2013).

The purge of Peronist officers resulted in the forced retirement of approximately 500 officers, many of whom were from the 60th to 74th graduating classes of the Military Academy. This affected officers from various branches, including infantry (53%), cavalry, and artillery. The vacancies left by their removal were often filled by less updated or less capable officers, which weakened the Army’s upper ranks.

Simultaneously, the Liberating Revolution reinstated around 180 anti-Peronist officers who had previously been dismissed. Many of these individuals later ascended to high-ranking positions within the military hierarchy, with some achieving the rank of general. The restoration of these officers solidified the influence of a military faction closely aligned with anti-Peronist ideology, significantly shaping the institution's leadership and operational outlook for years to come.na visión conservadora y antiperonista, que jugaría un rol crucial en los años venideros.

The "Blues" and the Consolidation of Military Power

Following the coup, the faction known as the "Blues" emerged as the dominant faction within the Army, consolidating its control throughout the 1960s and 1970s. This faction, under the leadership of figures such as Alejandro Lanusse and Alcides López Aufranc, imposed a militaristic and conservative vision that influenced both internal politics and Argentina's participation in territorial conflicts and the anti-subversive war. This faction managed to stay in power through a network of internal loyalties and through control of promotions and retirements within the military institution.

The Ideological and Operational Legacy

The impact of the Revolución Libertadora was not limited to a reconfiguration of the military hierarchy, but established a doctrine that would influence key events in Argentine history, such as the anti-subversive struggle and the conflict in the Malvinas Islands in 1982. The work underlines how this militaristic ideology promoted violent intervention in both internal and external conflicts, in defence of "national sovereignty" and the stability of internal order.

The changes in the composition and profile of Army officers during the Liberating Revolution significantly influenced military decisions in the following decades, particularly in how the Army approached counterinsurgency operations and territorial conflicts. The training and consolidation of these cadres during and after the Liberating Revolution instilled a distinctly aggressive decision-making style, exemplified by the harsh measures employed during the military dictatorship’s counterinsurgency campaign. This period saw the implementation of violent repression strategies against any perceived threat to the established order.

Moreover, the establishment of a high command that favored the use of force and embraced a nationalist perspective played a critical role in decisions such as the escalation of tensions during the Beagle Channel conflict with Chile in the 1970s and the invasion of the Malvinas Islands in 1982. The dominant ideology among these military officers—shaped during the Revolución Libertadora (1955 Revolution) and solidified in the subsequent decades—portrayed the Army as the guardian of national sovereignty against external enemies and as the enforcer of internal order against perceived subversion.

Professional soldiers trained under this doctrine operated with a clear and uncompromising premise: all problems were to be resolved militarily. Ambiguity was not an option. They assessed situations, identified enemies, planned attacks, and executed operations decisively, relying on force or the threat of it. The first major adversary of this philosophy was its ideological nemesis: the dictator Juan Domingo Perón. Subsequently, internal power struggles between factions emerged, including the infamous Azules versus Colorados clashes, leading to decades of military uprisings and internal conflicts.

Conflict resolution within this faction of the Argentine military was consistently taken to extremes. The failed coup of 1951, the bombing of Plaza de Mayo on June 16, 1955, the decisive coup of September 13, 1955, the executions at León Suárez, and the series of coups throughout the 1960s left no doubt about the faction's uncompromising approach. On April 3, 1965, the 8th Tank Cavalry Regiment from Magdalena brutally attacked the Punta Indio Naval Air Base after being bombarded with rockets and napalm by naval aircraft. This level of unrestrained aggression became the norm.

A mentality shaped by the spirit of blitzkrieg dominated operations during the counterinsurgency campaigns, the near-war territorial disputes with Chile in 1978, and the climactic recovery of the Malvinas Islands. Operations such as Soberanía and Tronador exemplified this mindset. These plans were masterpieces of military strategy, marked by creative approaches and the ability to anticipate Chilean responses several steps ahead. They encapsulated the lessons learned by the officer corps, meticulously applying the most advanced military doctrine of the era.

The reliance on military solutions did not end there. The Carapintada rebellions and the brutal retaking of the 3rd Mechanized Infantry Regiment at La Tablada marked the closing chapter of a generation of soldiers forged for war. Often unable to resolve matters through other means, they consistently chose the use of military force as their primary response.

The negative consequences of this approach were evident in the widespread social condemnation of the methods employed during the counterinsurgency campaigns. The defeat in the Falklands War delivered the final blow to this mindset, leaving not only a profound loss of life but also a deep scar on national pride.

From a more positive perspective, the Argentine military approached their profession with uncompromising consistency, making decisions rooted firmly in military doctrine. Despite errors, indecision, and the brutalities committed, their actions often adhered to rigorous operational planning. Notable examples of military precision included Operation Rosario, an amphibious assault brilliantly executed against an enemy garrison with the explicit objective of avoiding casualties. Additionally, Argentina became the first country to simultaneously dismantle two terrorist movements—one urban and one rural—through a decentralized and audacious operation involving all military and police units to neutralize insurgent hideouts.

However, this war was later scrutinized in Argentine civil courts through a judicial process marred by irregularities, including the retroactive application of laws and improper proceedings that remain controversial. One critical misstep in the military’s counterinsurgency method was the disposal of insurgents’ bodies instead of returning them to their families, a decision that continues to fuel contention.

A Reflection on Military Responses and Leadership Failures

Allow me a personal reflection. One expects a military response from the armed forces; otherwise, there is no reason to call on them. When the military is summoned to address a problem, it is understood that the issue will be resolved manu militari. This entails frontal assaults, flanking maneuvers, precision strikes, saturating defenses, and seeking the enemy's surrender. The generation of Aries, guided by the Roman god of war, responded as expected—sometimes with massive errors, but always consistent with how the nation had trained them.

I deeply detest, with significant conviction, when a military officer ventures into political analysis, planning, or implementation for a real-world problem. When a tactician delves into geopolitics instead of focusing on executing orders from their superiors, it reflects a clear lack of professionalism. Such failures have existed, continue to exist, and will likely persist. A case in point was the HMS Shackleton incident, when the British oceanographic vessel intruded into Argentine waters in a blatant affront to national sovereignty. Intercepted by the ARA Rosales, the naval command from Libertad headquarters issued a direct order: "Sink it!" However, the naval officer in charge chose instead to have a coffee—a gesture that not only dishonored his uniform but also assumed roles reserved for the General Staff.

In 1982, General Luciano Benjamín Menéndez, as Argentina's military governor in the Malvinas, was tasked with designing the defensive plan against a potential British re-invasion. His plan, however, was a static defensive setup devoid of imagination or strategy. It resembled something conceived by a Chilean general—lacking in creativity and more concerned with maintaining good relations with the kelpers (the British-settled population) than defending the territory. When the enemy landing at San Carlos was detected, Menéndez's response was painfully reactive, if it could even be called that.

From that moment, events spiraled downward. There were no ambushes planned, no maneuvers to regroup forces, and no flanking or encirclement strategies implemented. Menéndez left each position commander to act independently, offering no centralized coordination or leadership. What emerged was a general with little intellect and even less courage, paralyzed by mediocrity, passively awaiting the inevitable. He failed to optimize the resources at his disposal, whether abundant or scarce. Instead of leading, Menéndez surrendered to inertia, displaying a complete lack of strategic vision and leadership. This was the cost of nepotism—elevating an officer tied to families associated with the Revolución Libertadora and the counterinsurgency campaigns. Menéndez prioritized geopolitical relations with those who despised him rather than focusing on his troops and crafting the best possible military plan.

A Broader Legacy of Patriotism

Despite the tragic context of Latin America, this generation of Aries left behind a lesson in patriotism that transcends generations. The shameful examples of Cuba, Venezuela, and Nicaragua—where senior military officers, lacking ethics, morals, and discipline, handed their nations over to petty dictators—stand as cautionary tales of what Argentina could have become. Yet, in Argentina, a cadre of patriotic officers emerged. When a dictator like Perón sought to perpetuate his rule, it was the brave 18% of troops who rose in rebellion to depose him. This is not the cursed Caribbean; this is Argentina. And in Argentina, when the military acts with honor, it does not surrender its homeland to tyrants.

Lessons from the Liberating Revolution

The Liberating Revolution not only restructured the Argentine Army and the entire armed forces in terms of their composition, but it also laid the ideological and operational groundwork for the decisions that would shape the nation’s military history in the decades that followed. From this experience, both positive lessons and critical errors emerge. It is our generation’s duty to learn from both as we shape the doctrine that will restore us to the military power we were destined to be.

Integrated Naval Base in Ushuaia: Perspectives and Antarctic Geostrategy

 

Analysis of the Integrated Naval Base in Ushuaia and Its Impact on Argentine Claims in the Antarctic Treaty Re-Negotiation

1. Strategic Importance of the Integrated Naval Base in Ushuaia

The Integrated Naval Base in Ushuaia, Argentina, represents a significant geostrategic development in the South Atlantic and Southern Ocean. Located at the southernmost tip of South America, this base offers Argentina a direct operational gateway to Antarctica, enhancing its ability to project maritime, scientific, and logistical capabilities in the region. The base strengthens Argentina's naval infrastructure, allowing for increased surveillance, patrolling, and the potential control of maritime chokepoints, especially around the Drake Passage, which is a critical maritime corridor.

The base is expected to support naval, coast guard, and scientific missions. Its dual-use capacity (military and scientific) provides Argentina with a legitimate presence in Antarctic-related activities, aligning with its obligations under the Antarctic Treaty while also reinforcing its geopolitical claims.

2. Transformation of Argentine Leverage in Antarctic Treaty Re-Negotiations

The Antarctic Treaty, established in 1959, is set to face re-negotiation pressures in 2048, as some signatories may seek to alter its key provisions, particularly those related to the extraction of natural resources. Argentina has a historical claim to a portion of Antarctica, overlapping with British and Chilean claims. The Ushuaia base will be a major strategic asset for Argentina during this renegotiation process for several key reasons:

1. Enhanced Physical Presence: The proximity of the Ushuaia base to Antarctica enables Argentina to demonstrate a "continuous presence" in the region. This presence matters under international law, as it strengthens sovereignty claims. Permanent facilities that support both scientific research and naval operations could bolster Argentina’s claim that it has an enduring and effective presence in its claimed sector of Antarctica.

2. Scientific Leadership: Argentina has already invested in Antarctic research, and the Ushuaia base provides expanded logistical support to its Antarctic research stations. This enables Argentina to increase its contributions to scientific discovery, which is a core pillar of the Antarctic Treaty. By leading in scientific research, Argentina can argue for a greater say in future treaty negotiations.

3. Maritime and Security Control: The Ushuaia base provides Argentina with the capacity to oversee maritime activities around Antarctica, especially in fishing, resource exploration, and illegal incursions. By controlling these activities, Argentina may position itself as a key steward of Antarctic conservation, while also subtly reinforcing the legitimacy of its claims.

4. Symbolic Power and National Prestige: Establishing a high-profile naval base at Ushuaia sends a symbolic message to domestic and international audiences. Domestically, it reinforces the Argentine government’s narrative of asserting sovereignty. Internationally, it signals to other claimants (notably the UK) that Argentina is serious about its Antarctic ambitions and will actively defend its position during any future negotiations.

---

3. Potential Geopolitical Consequences

• Shift in Balance of Power: Argentina's increased capacity to project power from Ushuaia could shift the balance of power in the South Atlantic, potentially challenging the UK's position in the Falklands/Malvinas dispute. Enhanced Argentine patrols may create diplomatic friction, especially if Argentina increases inspections of foreign-flagged vessels near the Antarctic region.

• Increased Regional Competition: Chile and Argentina have overlapping Antarctic claims. The development of the Ushuaia base could prompt Chile to respond with its own enhanced infrastructure. Brazil, another Antarctic Treaty signatory, may also perceive this as a sign to strengthen its role in Antarctic affairs.

• Linking the Antarctic to the Malvinas/Falklands Dispute: Argentina may attempt to link its Antarctic ambitions with its broader sovereignty claims over the Malvinas/Falklands. The operational capacity provided by the Ushuaia base would enable Argentina to strengthen patrols around the islands, adding pressure on the UK and heightening the symbolic link between its Antarctic and Malvinas/Falklands claims.

---

4. Final Assessment

The Integrated Naval Base in Ushuaia is a critical enabler of Argentina’s long-term strategy to secure a prominent role in the future of Antarctica. It provides Argentina with enhanced strategic, operational, and symbolic leverage. By expanding its physical presence, scientific contributions, and security role in Antarctic affairs, Argentina will be better positioned to influence the renegotiation of the Antarctic Treaty in 2048. This endeavor also places Argentina in a stronger geopolitical position in the South Atlantic, with potential repercussions for its relations with Chile, Brazil, and the UK.

Commandos in Malvinas: Lack of Technique and Doctrine in Reconnaissance Missions

Reconnaissance Patrols Without Technique or Doctrine

Reconnaissance Patrols Without Technique or Doctrine

Excerpt taken from the book "Comandos en Malvinas - The Other Story," chapter "Analysis of Operations." The book is available in print and e-book format on Amazon.

Without a doubt, it can be said that within the Argentine Army (EA), the Argentine Navy (ARA), and the Argentine Air Force (FAA), there was no clear doctrine regarding the use of commando units for reconnaissance tasks. Incredibly, reconnaissance missions were considered secondary and even looked down upon within the different units and in the commando training course itself. In this course, barely any time was devoted to such missions, when, as we all know, any technique is mastered by precisely dedicating time to it and practicing it repeatedly.

The problem in the Argentine case was that many of these techniques were simply unknown. A reflection of the perception of reconnaissance operations within Argentine units can be seen in comments made by Major Rico in several interviews. The commander of the 602 Commando Company stated that his men were wasted on reconnaissance missions when they should have been used for raids against high-value targets. According to Rico's exact words, exploration missions were not worth the effort and could be carried out by other units.

This outdated mindset among the Argentines regarding reconnaissance patrols, along with its resulting consequences, was in complete contrast to the practices followed at the time by units in countries with experience and ongoing conflicts, such as Israel, South Africa, and NATO nations. In these countries, reconnaissance missions occupied a large portion of training hours and unit resources, and they were valued by general headquarters as force multipliers and a high-value resource for the development of subsequent operations.

NATO countries had even established an international training school for deep reconnaissance patrols in 1979 in Weingarten, Germany. This center aimed to improve procedures, standardize protocols, and reduce training costs. The Soviet Union also placed great importance on reconnaissance patrols.

After the Malvinas conflict, the operations carried out by Argentine commandos were studied in many training centers and military schools worldwide, serving as a model of "what not to do." For example, at the John F. Kennedy Special Warfare Center and School (SWCS) at Fort Bragg, U.S.A., the errors committed by Argentine patrols were part of the curriculum from 1984 until at least 1992. But it was especially at Weingarten, thanks in part to British instructors assigned there, that the serious mistakes of Argentine commando units were widely disseminated and known at the international level. From then on, these errors were used in commando schools and training courses in many countries as examples of the mistakes to avoid.

An old military adage says, "Time spent on reconnaissance is never wasted time," a principle that the Argentine Armed Forces and their commando units did not seem to have internalized — and had to learn the hard way.

Beagle Crisis: The Beagle/Cape Horne Air Naval Battle

Beagle Crisis: The Fleets Face Off in the Southern Sea

By Esteban McLaren for FDRA

On December 22, 1978, D-Day, coordinated military actions along the borders with Chile would have commenced as part of Operation Sovereignty. It is difficult to determine with certainty which of the planned actions would have officially initiated the war, but it is clear that a simultaneous assault on at least four fronts would have taken place. The primary front would have been the naval battle and landing in the Beagle Channel, where the Argentine Navy's Marine Corps (IMARA) would have deployed troops to the Lennox, Nueva (already occupied by Chilean Marine Corps, CIM), and Picton Islands.

The purpose of this article is to explore an alternative history scenario. The war never took place, but what would have happened if Argentina had not accepted papal mediation?

In December 1978, tensions between Argentina and Chile over the sovereignty of the Picton, Lennox, and Nueva islands in the Beagle Channel reached a critical point. Diplomacy had failed, and both countries were preparing for armed confrontation. The Argentine Fleet (FLOMAR), with its powerful combination of aircraft carriers, cruisers, destroyers, and submarines, was preparing to face the Chilean Navy (ACh), a well-equipped force but at a numerical and technological disadvantage. Chilean authors speculate that in terms of infantry, Argentine forces roughly doubled the Chileans in size; in terms of armored vehicles, the ratio was 5:1; for aircraft, 3:1; and in naval strength, Argentina was slightly superior in some aspects (surface combatants), decisively superior in others (submarines operating in the area), and qualitatively unmatched in yet another (aircraft carriers).

Order of Battle as of December 20, 1978

  • High defensive capability with frigates equipped with Exocet missiles.
  • Limited submarine capacity, with only one operational submarine.
  • Good coordination between surface and air units.

• Quantitative:

  • 2 light cruiser
  • 3 frigates
  • 6 destroyers
  • 1 operational submarine

Argentine Fleet (FLOMAR)

• Qualitative:

  • Air superiority with the aircraft carrier Veinticinco de Mayo.
  • Greater submarine capacity with 4 operational submarines.
  • High force projection capability with modern destroyers and frigates.

• Quantitative:

  • 1 air carrier
  • 1 light cruiser
  • 8 destroyers
  • 2 missile corvettes
  • 4 submarines

 

Conflict Escalation

The conflict did not de-escalate; on the contrary, it worsened. The Argentine Fleet (FLOMAR) decided to launch an attack on the Chilean Navy, which quickly set sail from Valparaíso heading south toward the Beagle Channel. The last detected position of FLOMAR was 120 miles (some sources cite 193 miles) southwest of Cape Horn, preparing to support Operation Sovereignty, whose primary objective was the amphibious landing and capture of the Picton, Lennox, and Nueva islands.

 

Capabilities Analysis

Chilean Navy (ACh)
The ACh possessed a light cruiser, destroyers, and frigates, all equipped with anti-air and anti-submarine defense capabilities. However, operational issues with the SS Simpson left the fleet without effective submarine coverage, a critical disadvantage in modern naval warfare.

Argentine Fleet (FLOMAR)
FLOMAR, on the other hand, had the advantage of the aircraft carrier ARA Veinticinco de Mayo, which provided air superiority with its A-4Q Skyhawks. The modern destroyers and multiple operational submarines gave FLOMAR a robust capacity for both defense and attack.

 

Key Points of Advance and Refuge Locations for the Chilean Navy (ACh)

To reach the Beagle Channel, the Chilean fleet would advance southward from Valparaíso, passing through Puerto Montt, the Chacao Channel, the Gulf of Penas, Bahía Inútil, and the Strait of Magellan, before heading toward the Beagle Channel. If refuge were needed, Chilean fjords such as the Última Esperanza Fjord, Quintupeu Fjord, Aysén Fjord, or Comau Fjord would serve as strategic locations to hide and launch counterattacks.

Quintupeu and Comau Fjords

 
Última Esperanza Fjord or Sound

Final Approach to the Beagle Channel (or Cape Horn)

The upper map shows the route of the Chilean fleet according to official Chilean and Argentine bibliographies.

Note that the Chilean fleet’s course passed over the position of the ARA Santa Fé submarine because it had detected them precisely days before December 21. In other words, the enemy fleet had already been detected and followed by a submarine of the Argentine Submarine Force (CFS). The fleet was heading south of Cape Horn to combat stations, with two ships anchored side by side, awaiting orders to attack. The ships were arranged in this manner to allow for personnel exchange and social interaction while waiting (Arancibia Clavel & Bulnes Serrano, 2017). We will return to this point later.

Detection and Engagement Strategies

The Argentine Fleet (FLOMAR) would employ its S-2 Tracker and P-2 Neptune aircraft for reconnaissance missions (as they would successfully do four years later in the Malvinas), and the A-4Q Skyhawks for attacks, while Argentine submarines would ambush Chilean ships at critical points in the Strait of Magellan and the Drake Passage. FLOMAR’s destroyers and frigates would provide fire support and anti-aircraft defense to protect amphibious and heliborne assault operations.

Once again, it is enlightening to refer to the "official" account of the Chilean fleet’s movements (Arancibia Clavel & Bulnes Serrano, 2017). In this text, it is detailed how Chilean officers trained on a land-based simulator (this is not a joke) called Redifon, which consisted of interconnected cubicles simulating ships, and practiced maneuvers in the basement of the Tactical Training Center of the Naval War Academy in Valparaíso. Merino and López, practicing on this analog simulator, tried various attack combinations on the FLOMAR and concluded that they had to achieve "control of the sea," aiming for a decisive naval battle in the style of Mahan. The outcome of these exercises determined an optimal attack formation where "all missile-equipped ships would go ahead, with gunnery ships behind" (p. 86). I don’t understand why the Redifon was even required for something that seems like common sense. Or was there perhaps some logic to sending the gunships first (Prat, Latorre) and the missile ships behind (Almirante-class, Leander-class)?

FLOMAR, on the other hand, "lacked" such a simulator simply because the crews spent most of the naval year on board, maneuvering with real ships in real time and facing real problems. Approximately two-thirds of the year, the crews remained on board—a fact anyone with relatives in the Argentine Navy at that time can corroborate. Many sailors during this golden era of the Argentine Navy only met their children when they were 8 or 9 months old, as their life at sea prevented earlier visits. The distance between both fleets, beyond the geographic one, was astronomical.

 

Analysis of the Clash of Forces

Within the framework of the 1978 Beagle Crisis, tensions between Argentina and Chile reached a critical point, bringing both nations to the brink of armed conflict. Operation Sovereignty, planned by Argentina, had as its primary objective the amphibious landing and capture of the Picton, Lennox, and Nueva islands, located in the Beagle Channel. This operation was to be conducted under strong naval and air cover provided by the Argentine Fleet (FLOMAR).

Preparations and Force Composition

By late December 1978, FLOMAR was fully equipped and ready for action. It had at its disposal the aircraft carrier ARA Veinticinco de Mayo, a crucial asset that carried A-4Q Skyhawks and S-2 Trackers, providing both air interception and maritime patrol capabilities. The fleet also included several modern destroyers, such as the ARA Hércules (the only one equipped with medium range naval SAM like the Sea Dart), as well as frigates like the ARA Piedrabuena and ARA Espora. Additionally, Argentina possessed a significant submarine force with the ARA Santiago del Estero, ARA Salta, ARA Santa Fe, and ARA San Luis submarines.

The Chilean Navy (ACh), although smaller in number, maintained a robust defensive force. Its primary asset was the light cruiser CL-02 Capitán Prat and the still formidable Almirante Latorre, accompanied by frigates and destroyers equipped with MM-38 Exocet missiles. The Chilean fleet also included the submarine SS-21 Simpson, the only operational submarine at the time, as the other Oberon-class submarines were undergoing major maintenance.

 

Operation Development

The landing operation planned by Argentina focused on Isla Nueva, where it was known that around 150 Chilean marines were entrenched. The Argentine strategy was to land on the southern coast of the island, avoiding Chilean defenses in the north. To execute this, the amphibious transport ARA Cabo San Antonio would be employed, escorted by destroyers and frigates providing fire support and protection.

The Chileans anticipated a conventional landing on the islands, when in fact, the most likely scenario was that the occupation would be carried out via vertical assault using helicopters.

The final phase of FLOMAR’s approach was established with the Argentine fleet advancing from its last detected position, 120 miles south of Cape Horn, moving eastward toward the Beagle Channel. Meanwhile, the Chilean Navy (ACh) mobilized from Puerto Williams, heading toward the channel to intercept the Argentine forces. Here, two simultaneous courses of action can be evaluated: first, the main fleet moved toward the Drake Passage to engage FLOMAR in open waters; second, the smaller torpedo boats (Quidora, Fresia, Tegualda, and Guacolda) would confront the landing force.

Submarine Warfare

The book La Escuadra en Acción by Arancibia Clavel and Bulnes Serrano recounts the military and political activity during the conflict, with a focus on the Chilean Navy. Although the text is not highly technical regarding the means employed, it provides an interesting general description of the operations of the Chilean fleet in the south.

In this account, it is mentioned that the Chilean Submarine Force was composed of the Balao-class submarine Simpson (SS-21) and the modern, for the time, British Oberon-class submarines named Hyatt (SS-23) and O'Brien (SS-22).

According to this source, the O'Brien was in dry dock during the conflict, and the Hyatt had to interrupt its transit south and return to its base in Talcahuano due to a mechanical failure. The other Balao-class submarine, the Thomson (SS-20), is not even mentioned, possibly because it had already been decommissioned due to its age. In fact, both Brazil and Argentina had retired their submarines of this class in the early 1970s, after receiving the Guppy class.

Although the Simpson was technologically outdated for the circumstances, it managed to fulfill its mission. The old submarine had to surface frequently to recharge its batteries, dangerously exposing itself to Argentine radars and periscopes. It was photographed at least twice by Argentine submarines while on the surface. Due to its wear, it is not surprising that this operation had to be performed more frequently than usual. The Simpson was detected twice by Argentine submarines, which chose not to fire their torpedoes. Nonetheless, it is possible that its commander, Rubén Scheihing, attempted to attack despite his technological disadvantage.

Patrol Areas Assigned to the Argentine Submarines

Although the exact dates cannot be confirmed, the Guppy-class submarines were very close to engaging in combat, although fortunately, their commanders interpreted their orders with sound judgment. In mid-December, the Santa Fe submarine was patrolling the entrance to Bahía Cook at a depth of 50 meters. The sonar operators detected the sound of approaching warship propellers. The commander of the S-21 raised the combat alarm, the crew took their positions, and all torpedo tubes were prepared for launch. The propeller sounds grew in number, eventually forming what appeared to be "a fleet." The Chilean squadron sailed above the S-21, heading into the open waters of the South Pacific.

The sonar operators counted three, four, six... up to 13 ships. Some had "heavy" propellers, like cruisers, while most had "light" propellers, similar to those of destroyers.

However, the Chilean fleet was sailing without emitting signals, meaning they were not using active sonar on the escort ships. A fleet commander's decision to sail without emitting can have several justifications, such as not actively searching for submarines or preferring to be more discreet, as sonar emissions propagate over great distances and can be detected by submarine countermeasure equipment, revealing their course or trajectory.

It is not difficult to imagine the immense tension experienced by the crew of the Santa Fe. Suspended in silence dozens of meters below the Pacific, they awaited the Chilean fleet's actions, with weapons ready to launch if the right moment came to strike from a tactically advantageous position.

Ultimately, the Chilean fleet entered open waters, moving away from the S-21. Following his orders, the commander of the Santa Fe did not interpret the Chilean fleet's maneuver as a hostile act, especially at a time when there was no formal declaration of war.

This situation clearly shows that the ARA Santa Fe was aware of the Chilean fleet's position and, in the event of war, it would have been the first to launch torpedoes against the Chilean fleet.

Meeting and Engagement Point

The meeting point of the fleets would be near the Beagle Channel. FLOMAR had to face the threat of the ACh's MM-38 Exocet missiles, with a range of 35-40 km. There is a recurring narrative in dialogues, discussions, and exchanges with trans-Andean experts and novices alike that suggests a certain accounting of Exocets, leading to the assumption that a potential naval battle would "clearly" tip in favor of the ACh. At that time, Chile was thought to have 4 to 8 more missile launchers than the ARA. This is the denial of the evident Argentine advantage, as these opinion shapers tend to overlook the key assets of the ARA: its aircraft carrier and its four operational submarines. For greater clarity, the aircraft carrier ARA Veinticinco de Mayo provided Argentina with a significant advantage, enabling attacks from distances of over 200 miles (370 km). Another key factor, when compared with the experience in the Malvinas, is that the Argentine Naval Aviation had full experience in anti-ship attacks, and the bomb fuses would have been correctly adjusted to detonate on impact with the ships. Once the Chilean fleet was detected by the S-2 Tracker and P-3 Neptune aircraft, its position would be relayed to FAA airbases and the CFS submarines, and it would only be a matter of time to see who would arrive first to the hunt.

Landing and Engagement Scenarios

1. Chilean Fleet’s Approach to Stop the Landing
   The Chilean Navy (ACh) would rapidly advance from Puerto Williams toward the Beagle Channel, deploying its frigates and destroyers to intercept and attack the Argentine landing forces. Fast attack craft would also be used to disrupt the landings and support vessels. The Chileans would launch Exocet missiles and use naval artillery to harass the landing craft. Additionally, they would coordinate air strikes from Punta Arenas using Hawker Hunter and A-37 Dragonfly aircraft. Entering the Beagle Channel is a losing strategy for either fleet due to restricted movement, sensor disruption caused by terrain clutter, and the consequent degradation in weapon performance.

2. FLOMAR’s Response to This Movement
   In response to the Chilean approach, FLOMAR would deploy its A-4Q Skyhawks and S-2 Trackers from the aircraft carrier to conduct preemptive strikes against ACh units. Argentine submarines would patrol strategic areas to intercept Chilean ships. FLOMAR would use its air defense systems to intercept approaching aircraft and launch its own anti-ship missiles to neutralize key threats. Unlike the Chilean fleet, the Argentine Navy had an external attack element in the form of carrier-based aviation. The confined space of the channel would facilitate an air-naval attack and would have been ideal for a sequence of attacks followed by rearming to restart the cycle.

3. ACh Focuses on Seeking Out FLOMAR for Direct Defeat
   Based on the cited literature, this was the path chosen by the Chilean Navy. If the ACh had decided to seek out and directly confront FLOMAR, they would have circled Navarino Island or approached via the Drake Passage toward Cape Horn (southeast route). They would coordinate with the Simpson submarine and aerial patrols to locate the Argentine fleet, launching missiles and naval artillery strikes as soon as they detected it. According to the same literature, the ARA Santa Fe was positioned beneath the fleet when it entered open waters, meaning the target was detected first. Again, in this scenario, the Argentine naval aviation would have encountered them halfway, in any case, forcing them to endure several waves of A-4Q Skyhawk attacks. What remained of these waves would be what could confront an intact FLOMAR. Checkmate.

4. FLOMAR Focuses on Seeking Out ACh for Direct Defeat
   If FLOMAR decided to seek out and directly confront ACh, it would advance from its position south of Cape Horn toward the northeast. They would use their carrier-based aircraft for reconnaissance and attack, first launching repeated air strikes to sink or disable the main surface assets, followed by attacks to sink or damage various ships. They would then move closer to launch anti-ship missiles from their destroyers and frigates, coordinating strikes with their submarines.

   Here we recall the ACh's "combat station" formation: the ships were anchored side by side to share the wait with social interaction and the exchange of supplies. If the ARA had launched its A-4Q Skyhawks while this formation was still in place, it would have greatly facilitated the effectiveness of the bombs. A single bombing run by three aircraft with three 450-kilogram bombs could have impacted two ships at a time, doubling their efficiency. Checkmate.

Roles of Naval and Military Aviation

• Argentine Carrier-Based Naval Aviation:

  • A-4Q Skyhawk: These aircraft would conduct interception and air superiority missions, as well as attacks on enemy ships to protect the landing forces. A total of 8 units were carrier-based.
  • S-2 Tracker: These aircraft would perform maritime patrols, submarine detection, and coordination of anti-submarine and anti-ship attacks. 2 units were carrier-based.
  • P-3 Neptune: Operating from land bases, these long-range aircraft had highly trained crews who conducted year-round missions in the Argentine Sea.

• Naval Aviation Based in Río Grande:

  • T-28 Fennec: These aircraft would perform close air support missions and ground attacks to cover the landing forces (deployed in Río Grande and Estancia La Sara). A total of 19 units.
  • MB-326 Aermacchi: These aircraft would carry out interdiction and ground attack missions to support amphibious and land operations (Río Grande). The exact number of units is undetermined.
  • T-34C Turbo Mentor: These aircraft would undertake light attack missions, logistical support, and supply transport. More than 12 units.

• Chilean Military Aviation in Chabunco:

  • Hawker Hunter: These aircraft would perform interception and air combat, ship attacks, and provide support to ground forces (6 units).
  • A-37 Dragonfly: These aircraft would conduct ground attacks, close support, interdiction, and harassment of Argentine landing forces (12 units).

• Argentine Military Aviation in Río Gallegos:

  • A-4B/C/P Skyhawk: These aircraft would carry out attacks on ships and provide support to ground forces, as well as interception and air combat when necessary (12 units).
  • Mirage IIIEA/Mirage 5 Dagger/IAI Nesher: More than 30 units of the three models combined.
  • F-86 Sabre: These were pure interception fighters, deployed to engage the Hawker Hunters due to experience gained during the Indo-Pakistani wars. The exact number is unclear, but pilot reports suggest there were more than 4 units and less than 14.
  • Their objectives were first to initiate bombings against military targets in the cities of Punta Arenas (Chabunco airbase) and Puerto Williams (Zañartú airfield) and to destroy the Chilean Air Force, using a technique very similar to that employed by Israel in the Six-Day War of 1967. The same approach would be implemented across all active fronts.

 

A-4Q Launched from the Aircraft Carrier ARA Veinticinco de Mayo Strikes the ACh APD-29 Uribe

 

The offensive against Chile would follow the following sequence: (Wikipedia):

• Starting at 20:00 hours (H-2) on D-Day, December 22, 1978, FLOMAR and the Marine Infantry — Battalion No. 5 — would occupy the Freycinet, Hershell, Wollaston, Deceit, and Hornos islands (see map below).
• At 22:00 hours, the designated H-Hour, FLOMAR and marines — Battalions No. 3 and No. 4 — would occupy the Picton, Nueva, and Lennox islands, also gaining control of the Beagle Channel (see map below).
• The ground offensive would begin at 24:00 hours (H+2). The V Army Corps would launch an attack from the Santa Cruz area, aiming to conquer as much Chilean territory as possible in the Patagonian region. Simultaneously, the Argentine Air Force would begin strategic bombings.
• At 06:00 hours (H+8) on December 23, 1978 (23.06:00.DEC.978), the destruction of the Chilean Air Force on the ground would commence.

 

The naval confrontation between Argentina and Chile in 1978 would have been a complex, multidimensional operation, involving naval, air, and ground forces in a challenging geographical environment. Argentina's air and submarine superiority gave it a significant advantage, though Chile's coastal defenses and tactical coordination offered formidable resistance. The outcome would have depended on numerous tactical and strategic factors, as well as the effectiveness in executing the planned operations by both nations.

In this specific scenario, it should be noted that the Argentine armed forces had three air bases on the front: one mobile (the ARA Veinticinco de Mayo) and two air bases in Río Grande and Río Gallegos, which would prove to be highly operational four years later in the Malvinas. In contrast, only the Chabunco air base in Punta Arenas would bear the burden of attempting to stop the landing operations, conduct anti-ship missions against FLOMAR, combat air attacks from the northeast (Río Gallegos air base) and from the east-northeast (Río Grande naval air base), and then plan ABA (Airbase Attack) operations against these same bases. Is that not too many objectives for a single runway?

For its part, the Argentine Naval Aviation (COAN) would focus exclusively on anti-ship strikes or very close air support, while the Argentine Air Force (FAA) would support the advance of the armored assault on Punta Arenas, conduct an ABA against the Chabunco air base, and ensure air superiority over Punta Arenas. Additionally, at the request of the Argentine Navy (ARA), the FAA would provide air support to the landing operations.

Probabilities of Success

Argentine Forces: With air superiority provided by the aircraft carrier and a modern surface fleet and submarines, Argentine forces had a significant advantage. The joint air-sea-submarine operations of FLOMAR would increase their chances of success.

Comparative Strength Between ACh (Left) and FLOMAR (Right)

The pink bands indicate the range of their main weapons (MM38 Exocet, 20 miles or 35-42 km). The aircraft carrier ARA Veinticinco de Mayo is represented by an A-4Q fully loaded with bombs and fuel, with a range of 350 km. These are the vital areas to cover before considering a real threat to the adversary. As an analyst, I find it difficult to even see a glimpse of equality between both forces.

Before analyzing the Chilean case, let us review the probability the Chilean Squadron had of repelling an air attack, which would have been the primary weapon of the Argentine Navy (ARA). Some Chilean destroyers (Almirante-class) were equipped with the British Short Seacat system. This is a small subsonic missile, powered by a two-stage solid-fuel rocket motor. In flight, it is guided by four cruciform wings and stabilized by four small tail fins. It is guided by command line-of-sight (CLOS) through a radio link, meaning flight commands are transmitted by a remote operator with both the missile and target in sight. The same system was installed on the Argentine carrier Veinticinco de Mayo and, in its land-based version (Tigercat), was deployed in Tierra del Fuego (IMARA) and Río Gallegos (Army). The missile proved highly inaccurate in the Malvinas conflict due to its lack of autonomy and reliance on the operator’s coordination of pulse and vision, with the inherent human eye difficulties in accurately perceiving depth and distance in space. Therefore, perhaps the best-equipped Chilean ship for self-defense against air attacks was likely the cruiser Almirante Latorre or Prat, with up to 14 Bofors 40mm pom-pom guns. These would have been the most difficult targets to approach and attack, and, if communications had allowed, the task might have been delegated to submarines.

Another intellectual exercise that no one has conducted, to my knowledge, is the following:

Chilean ships would approach at 21/28 knots (cruising speed/full speed) towards the Argentine naval forces (assuming that the CASA-212 aircraft correctly located them, as Chile had no other "eyes" available; there is a myth about electronic interception that is mentioned below). The distance to be covered was estimated to be between 140/193 miles according to various Chilean reports. This would take the Chilean fleet just over 5/8 hours of sailing to get within 20 miles of the Argentine ships (20 miles being the first point where they could attempt to strike the fleet, as that was the range of the MM38 Exocet missile, Chile’s only decisive weapon).

During those 5/8 hours, the ships would not be able to fire or damage the enemy. Meanwhile, during this period, the aircraft carrier ARA 25 de Mayo could launch and recover 3 to 5 combat sorties from its air group. Assuming each attack group flew at 400 knots round trip, landed, and took 25 minutes to reload bombs and refuel before taking off again, each A-4Q Skyhawk would take off with 3 bombs of 450kg on the central pylon, equipped with fuzes adapted to hit ships.

In the first pass alone, 24 bombs would be dropped on the "Squadron". Assuming no losses for the Argentine planes, by the fourth or fifth pass, between 96 and 120 bombs would have been dropped on the ships. Even if an Argentine plane was shot down in each pass, resulting in up to 4 losses, the worst-case scenario would still see up to 36 bombs launched against the "Squadron". In other words, before the Chilean fleet could close the gap between them and the enemy, they would have been hit by between 36 and 120 bombs (see the table below).

All of this would happen before any Chilean combat station operator could even press the launch button for a single Exocet missile. Do you understand how serious this plan was for the Chilean command? What were they thinking? Perhaps the worst part is that at the end of this death corridor, a fleet almost identical to the Chilean one in terms of surface combatants and Exocet launch capability, but completely intact, was waiting for them. Those who managed to survive would be met by a volley of French missiles.

Approximation times to 20 miles, passes, and number of bombs considering losses

Chilean Forces: The Chilean fleet in open waters was at the mercy of naval aviation first, and Argentine submarines later. As mentioned above, the distance between both fleets worked in favor of the FLOMAR. If the Chilean Navy had been detected at 190 miles, the bomb runs carried out by the Skyhawks would have left little afloat, even considering shoot-downs. It is almost sad to imagine a fleet speeding up to strike the enemy while being progressively bombarded over and over again with absolutely no help. Possibility of success: Zero.

Jorge Martínez Bush, a Chilean officer, stated the following in the book Soldados de Mar en Acción (Sánchez Urra, 2020), a compilation of the activities of the CIM.

"From what could have been the 'Naval Battle of Drake', then-Commander Jorge Martínez Bush, the second-in-command of the cruiser 'Prat', points out that 'we were about to enter combat, and we were prepared. In naval tactics, the position was in our favor because the sea and the wind worked for us, putting the Argentinians in a very complicated position' (p. 196)."

This officer accuses Vice Admiral López Silva of trusting the sea and the wind to defeat Argentine naval aviation. Did he take a pencil and paper and make a basic diagram to see if his statements had any foundation? What does Martínez Bush think about the air group (GAE) of the 25 de Mayo? Or did it not exist? If he is reading this, he could clarify this matter to the Chilean public. By the way, Sánchez Urra's account of the FLOMAR is suspiciously incomplete (he omits 2 Argentine submarines and speaks of "Chilean submarines" in the plural, portraying the Simpson as fully operational, on par with the Argentinians), which casts doubt on many other descriptions and lists presented throughout his work.

The other alternative was to hide in the fjords, which would have offered better chances of survival. However, with more than 100 enemy planes flying over their position and planning an attack, it was only a matter of time. The Chilean Navy was a serious opponent but completely lacked decisive weapons: neither aviation to disturb the two-dimensional plane nor operational submarines to attack from the complete stealth of the depths. Had the situation dragged on for only a week, it’s not unreasonable to think that the entire Chilean fleet would have ended up sunk or, for all practical purposes, out of combat. Possibility of success: Zero.

Defeat Scenario and Seeking Refuge in the Chilean Fjords

If the ACh suffered a defeat, a likely outcome would have involved the sinking or disabling of its main assets. In terms of naval target value, without a doubt, the Leander-class frigates would have been the primary focus of the attack, followed by the light cruisers Prat and Latorre, given their gunfire capability to affect landing operations. The remaining targets would have been defined by circumstance.

It’s worth adding here a piece of information that Admiral López Silva (theoretically the most prepared in naval-air warfare) of the ACh did not possess: Four years later, Argentine aircraft demonstrated that a fleet confined in a channel (like the San Carlos Strait) or very close to the coast (such as the southern islands of Cape Horn) was a perfectly reachable target for low-flying jet aircraft. The Royal Navy, equipped with much better air defense missiles than the ACh, only achieved a few isolated shootdowns, and only the failure of the fuses on bombs dropped by the FAA prevented its complete neutralization as a surface combat force before the end of the conflict. The attackers of the ACh would have been A-4 Skyhawks, both in their B and P variants, and Israeli Mirage fighters of the FAA, as well as the well-known A-4Qs of the COAN—all of which proved to be lethal in attacking a fleet. Did the Chilean fleet really expect a different outcome in their case?

If the ACh were to pass through the channel, it would ensure its demise. The fleet would be trapped in the Beagle Channel or advancing close to the southern coast of the islands, facilitating the approach of aircraft outside radar detection. The attack, as would later happen in the Malvinas, would take full advantage of the geography, just as it was in the San Carlos Strait. We now know that the likelihood of the main ACh units escaping an air attack was almost nil. Once the main units were disabled, the rest of the Chilean fleet would be attacked by Argentine destroyers and corvettes with their Exocets. This would not be the defeat chosen, according to the book by Arancibia Clavel and Serrano Bulnes.

The ACh would be forced to rely on air support from the Chilean Air Force (FACh), based at Chabunco airbase. At 6 AM on December 21, this base would be the primary target of a preemptive strike from all air assets stationed at BAM Río Gallegos. To make matters worse, if the Chilean fighters managed to take off, the COAN was lying in wait less than 200 km from Chabunco with a dozen T-28 Fennecs, ready to attack the Chilean fighters with machine guns and rockets as they landed.

Even so, if we consider that some units remained afloat after a defeat in the Fuegian channels, they would retreat to fjords such as Última Esperanza, Quintupeu, or Comau. With Argentine air superiority, Chilean forces would have little chance of success, as FLOMAR could carry out precise and sustained attacks. Without air superiority, Chilean forces would have a better chance of defending themselves, but they would still face a significant threat due to FLOMAR’s ability to coordinate attacks from both air and sea.

I want to add two final details before the conclusions. First, Chilean literature, whether academic or journalistic, as well as television media reports, engage in a repeated act of pretending ignorance. It is almost impossible to find books endorsed by the Chilean Navy (ACh) or other military forces, let alone by journalistic outlets, that mention the key word "A-4Q Skyhawk." Apparently, this weapon never existed in the theater of operations. And if it did, it was never a threat. In fact, they probably didn’t even fly. Oh, and the Argentine sailors got seasick due to rough seas. The books from the CIM or the “Squadron” pretend ignorance, as they reflect at all times, and absolutely without deviation, that what was going to take place was a naval battle, in the style of Jutland/Latakia. Two large fleets, now without cannons but with missiles, would come into firing range, each firing their volleys, and the better one would win. It almost seems as if the Argentine aircraft carrier was going to stay in the rear watching the scene, like a spectator in the stands.

This scenario is a complete disrespect to the informed reader. It is truly shameful that professional Chilean naval officers avoid addressing the clear impending air-naval battle and lie to their public by speaking of courage and patriotism to cover up what was entirely and fundamentally a technical issue. Sadly, Chilean "technical" literature is filled with this appeal to bravery rather than focusing on tools or tactics.

Finally, that same literature claims a level of information about Argentine forces' movements that surpasses what would be available today, even with two British AWACS donated as part of the collaboration during the Falklands War. Apparently, they had information on troop movements, aircraft movements, the position of the Argentine fleet, the order of operations of various units, and who knows what else. Moreover, this information was updated hourly. Not even with their own satellites would they have had such an instantaneous real-time picture. Apparently, Argentine communications had been "decoded," similar to Japan’s Purple Code. This is mentioned by anonymous authors using the mysterious term "electronic interception or tracking." Well, that was not the case. Argentine encrypted communications were not decoded. What naval intelligence actually did was maintain open channels to broadcast the information they wanted to be accessible to Chilean listening posts (counterintelligence). Argentine communications were indeed intercepted, but that happened in 1982, by NATO intelligence agencies, specifically from a station in Norway. But let’s never confuse NATO with Chile under any circumstances. In the previous statement, Martínez Smith himself comments that the Argentine fleet was an hour's sailing distance from the Chilean border, knowing this only through intercepted communications. Dear reader, in air-naval warfare, one does not order an attack on a fleet whose location has not been confirmed by one’s own sensors (an observer or radar providing the position). If FLOMAR was going to be attacked based on "intercepted" information, it was probably an ambush planned by the Argentine naval command.

The TransAndean Squadron, such as it was detected by the ARA Santa Fe submarine
 

In summary, the technological and operational superiority of FLOMAR granted the Argentine forces a considerable advantage in a direct confrontation with the ACh. The geography of the Chilean fjords would provide a natural refuge, but Chilean forces would still face significant challenges without the ability to counter Argentine air and naval superiority.

Retreat to the Fjords, Perhaps the Best Outcome for the ACh...

This report does not diminish the performance or the planning executed by the ACh. They did the best they could with what they had. That said, it wasn’t enough. The stars aligned to leave them without sufficient submarine capability (the SS-21 Simpson was detected and photographed twice before December 21, while their best submarines were undergoing major maintenance). Air support was going to be limited because they lacked a naval attack aviation force, and the FACh's air assets were going to receive their baptism of fire that same morning, meaning they would be fighting for their own survival. According to the plan, by the afternoon of December 21, Chabunco was expected to be inoperable—whether by FAA A-4 and Mirage strikes in the early morning or by T-28 Fennec/MB326 attacks throughout the rest of the day.

A criticism that can be leveled against López Silva’s plan is that he adhered to a Mahanian philosophy of seeking a decisive large-scale naval battle. He was committing the entire fleet ("all-in") in a maneuver where it would suffer many losses before even seeing the enemy on their radar screens. Once the events were set in motion, the fate of the Chilean fleet would be sealed for the rest of the conflict. This invites reflection on alternatives: when a smaller fleet faces a larger one, it should better rely on naval guerrilla tactics or small attrition battles. The Argentine Navy was born this way—facing much larger fleets, such as the Spanish and the Brazilian Imperial Navy, dragging them into small battles that favored minor but exhausting victories against the enemy. The fjords are an ideal setting for such a task: hiding ships to later conduct coordinated attacks. Even with enemy air superiority, this tactic can still be effective, as the Germans demonstrated during WWII by sheltering ships in protected fjords with dense layers of air defense and achieving success. This alternative would likely be more reasonable than facing a fully equipped aircraft carrier in open waters, without air superiority, and with an impaired submarine force. And here, the term "larger fleet" is more qualitative than quantitative—the Chilean "squadron" was going solo, with very little support from the depths and no air support, against naval pilots who trained intensively every year on how to sink ships and were highly skilled.

Did López Silva think that the ARA would bring its main naval assets within the range of Chilean Exocets for a gentleman’s duel? Was López Silva expecting a Jutland or a Latakia while heading into a Midway? Could it be that the Chilean naval command believed that the ARA would not exploit its submarine and naval air superiority by deploying its submarines and carrier-based fighters before they could even detect FLOMAR on their radars? Did López Silva think the A-4Q Skyhawks would not be launched against his ships? Long before a Chilean sailor would get the chance to press the launch button on an Exocet, the Chilean fleet would encounter the COAN and the CFS—either sequentially or simultaneously.
