ARA Bahía Buen Suceso (B-6) was a Bahía Aguirre-class 5,000-ton fleet transport that served in the Argentine Navy from 1950 to 1982. She took part in the Falklands War as a logistics ship tasked with resupplying the Argentine garrisons scattered around the Falkland Islands. Captured by British forces on 15 June after running aground at Fox Bay, she sank in deep waters while being used as target practice by the Royal Navy on 21 October 1982.
The invasion of South Georgia, also known as the Battle of Grytviken or Operation Georgias, took place on 3 April 1982, when Argentine Navy forces seized control of the east coast of South Georgia after overpowering a small group of Royal Marines at Grytviken. Though outnumbered, the Royal Marines shot down a helicopter and hit the Argentine corvette ARA Guerrico several times before being forced to surrender. It was one of the first episodes of the Falklands War, immediately succeeding the invasion on the Falkland Islands the day before.
The operation had been prepared on 19 March, when a group of Argentine civilian scrap metal workers arrived at Leith Harbour on board the transport ship ARA Bahía Buen Suceso without the required landing clearance and then raised the Argentine flag. The scrap workers had been infiltrated by Argentine marines posing as civilian scientists.
