Amid the Mirages, Skyhawks and Super Étendards of the 1982 Falklands War, the scrappiest Argentine aircraft of all was a stubby twin-turboprop that looked like it belonged in a different decade. The FMA IA 58 Pucará was slow, propeller-driven, and utterly outclassed by British jets — and it still managed the only air-to-air kill Argentina scored in the entire war.

Built for the wrong war, sent to another

The Pucara was designed as a counter-insurgency and ground-attack aircraft: a rugged, low-and-slow machine with tough landing gear, short-field performance, and the ability to haul cannon, rockets and bombs from rough, unprepared strips. That made it perfect for hunting guerrillas — and, on paper, useful for defending remote islands.

When Argentina seized the Falklands in 1982, around two dozen Pucaras deployed to island airstrips. But the war they found was not the one they were built for. Over the Falklands they faced Sea Harriers, naval gunfire, and British special forces — a far deadlier environment than any insurgency.

Caught on the ground

The Pucara's biggest enemy turned out to be the ground it sat on. On the night of 14–15 May 1982, an SAS raiding party slipped onto Pebble Island and destroyed six Pucaras where they stood, along with other aircraft. More were lost to Harrier attacks, naval bombardment and ground fire. For all its toughness in the air, the type was desperately vulnerable parked on an exposed airstrip.

The underdog's single victory

And yet, on 28 May 1982, a pair of Pucaras caught a British Army Scout helicopter on a casualty-evacuation flight and shot it down with cannon and machine-gun fire, killing its pilot. It was a grim moment — but it stands as the only air-to-air victory Argentina achieved in the whole conflict, scored not by a supersonic fighter but by a humble turboprop.

The Pucara ended the war mostly as wreckage scattered across captured airfields, and several were shipped to Britain as trophies. But it earned a strange kind of respect: a modest, rugged little attacker that punched far above its weight, and refused to be entirely written off.
