ARA Santa Fe was an Argentine Balao-class submarine which was lost during the Falklands War. Built during the Second World War, the submarine served in United States Navy as USS Catfish (SS-339) before being commissioned into the Argentine Navy in 1971. 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 sail visible above the waterline.
