HMS Plymouth was a Royal Navy Rothesay-class frigate. In 1982, Plymouth was one of the first Royal Navy ships to arrive in the South Atlantic during the Falklands War.

ARA Santa Fe was an Argentine Balao-class submarine that was lost during the Falklands War. Built by the US during the Second World War, the ship operated in the United States Navy as USS Catfish (SS-339) until 1971 when she was transferred to the Argentine Navy. She served until 1982 when she was captured by the British at South Georgia after being seriously damaged and subsequently sank along a pier, with just her conning tower (sail) visible above the waterline. The submarine was raised, towed out of the bay and scuttled in deep water in 1985.
