The Night of the Banzai

Brief Account of a Frustrated Attack on the British Fleet

On 25 April, the British recaptured South Georgia. From that moment, a tense calm settled over the Falkland Islands, as the Argentinians awaited the enemy's arrival. At that time, the Argentine Fleet at Sea was attempting to interdict the movements of the British Fleet. To this end, two Task Groups were deployed: one to the north of the Falklands, the other to the southeast.

The northern group centred around the aircraft carrier A.R.A. 25 de Mayo, from which Tracker aircraft were conducting reconnaissance missions to detect the enemy. By the end of April, authorisation had been given to open fire on enemy forces. On 29 April, with the carrier located approximately 150–200 nautical miles north of San Carlos Strait, long-range reconnaissance flights began. On the night of 30 April, signals intelligence detected British radar emissions to the N-NE of Port Stanley.

In the early hours of 1 May, a British Vulcan bomber carried out an airstrike on Stanley Airport, followed hours later by naval bombardment — the vigil in the Falklands was over. That same morning, a reconnaissance flight from the carrier returned with no radar contacts. However, at 1513 hours, a second flight detected radar contacts with six medium-sized vessels and one large ship — a British task force. The Argentine fleet now knew the enemy’s location. The British, however, were still unaware of Argentina’s position. The tactical advantage was clearly with Argentina.

However, the A-4Q Skyhawks lacked night-time operational and attack capability, preventing immediate offensive action. Reconnaissance efforts continued from the carrier to maintain contact with the British fleet and plan for an attack in the early hours of 2 May, involving six A-4Q aircraft, each carrying four MK82 bombs. The last known position of the enemy was obtained at 2300 hours on 1 May from a Tracker reconnaissance flight.

The British commander was aware he had been detected, but did not know the position of the Argentine naval force. His priority was to locate it, and he ordered Harrier reconnaissance flights. One such Harrier intercepted the Tracker mentioned earlier, which managed to evade it by flying low over the sea at night. Nonetheless, the Harrier had likely acquired a reasonably accurate estimate of the Argentine fleet’s location.

This prompted Argentine battle stations to be manned, and the destroyer Santísima Trinidad was authorised to launch missiles at the Harrier, though it never came within range.

During that night, the Argentine Battle Group went to combat alert at least three times, each time Harrier flights approached. Few slept. These incidents gave the British commander a clearer picture of the Argentine fleet’s position and combat capability.

After the conflict, the commander of HMS Invincible would remark:

“The Trackers were a real headache throughout the 45 days of combat. Knowing I had been detected, I launched my Harriers seventeen times to shoot them down, but I never succeeded.”

The tactical situation required maintaining contact with the British fleet. At 0528 on 2 May, a Tracker was launched to confirm enemy presence. Later that morning, a second Tracker would follow the location data of the first and continue surveillance to guide the attack of six A-4Qs.

The mission briefing was conducted by the ship’s Operations Department, attended by the Tracker crew and officers of the Third Naval Air Attack Squadron, where all operational details were decided. One unexpected issue delayed the mission: lack of wind, an uncommon condition in those latitudes.

In simple terms, bomb tables determine the number and type of bombs required to hit a target. In this tactical scenario, four bombs per aircraft were necessary. The actual wind was nearly calm, so even at full speed, the ship could only generate enough wind over the flight deck to allow the launch of aircraft carrying just one bomb each.

Although the mission briefing was complete, it was decided to wait for stronger winds to enable a proper launch with full bomb load.

Analysing the British air and anti-air capabilities, it was assessed that of the six A-4Qs to be launched, four could reach the target and drop their bombs, and two could return to the carrier. Of sixteen bombs, about 25% (four) might hit a ship — enough to neutralise an aircraft carrier if struck.

Launching with only one bomb per aircraft would likely cause insignificant damage, while risking loss of life and half of the carrier’s embarked strike and interception force.

The Tracker launched at 0528 failed to locate the British fleet, which had turned east, moving away from the Argentine battle group. However, throughout that morning, Harriers repeatedly approached, attempting to pinpoint the Argentine fleet, triggering frequent combat alerts aboard Argentine ships.

It is important to note that the Argentine naval group remained under the constant threat of air attack. This required a pair of A-4Qs to remain on deck, ready to launch within five minutes as interceptors. Each combat alert saw the aircraft launched on time, and in at least one or two instances, a second reserve section was also launched.

During a combat lull, the carrier’s commander spoke with the co-pilot of the lead Tracker aircraft and shared his tactical assessment: both fleets had comparable anti-air and anti-ship missile capabilities. The number of Harriers was assumed to be similar to that of the A-4Qs, and the latter were believed capable of engaging them successfully. When he mentioned the submarine threat, however, he added, "better not to think about it."

Committing six A-4Qs to an attack mission would have reduced the carrier’s interception capacity to zero. The remaining pair of aircraft onboard was intended to support the attack — one in reserve, the other as a tanker for mid-air refuelling of returning aircraft if needed.

The delayed reconnaissance flight took off at 1435 hours and conducted a maximum-range mission. It picked up both radar and electronic contacts and landed at 1900 hours. Upon returning, the crew noticed a change in the crew’s expressions on board — the A.R.A. General Belgrano cruiser had been sunk. The submarine threat had now become a grim reality.

In the days and nights that followed, combat stations were manned continuously.

Had the attack on the British fleet been carried out on 2 May 1982, it might be remembered today as the Day of Naval Aviation. But that was not to be. However, just two days later, a section of Super Étendard aircraft, guided by a Neptune patrol plane, sank HMS Sheffield — a clear demonstration of Argentina’s determination to fight.

That day, marking the baptism of fire of Argentine Naval Aviation, was later commemorated as the “Day of Argentine Naval Aviation”.

The night of 1–2 May has remained etched in the memory of its participants as the so-called:
“Night of the Banzai.”
