USS Cochino (SS-345)
USS Cochino (SS-345) was a Balao-class submarine laid down 13 April, 1944. Commissioning 25 August, 1945, Cochino joined the Atlantic Fleet. She received the GUPPY II modernization, which included improved engines, and a snorkel. In 1949, she was deployed to the UK, and participated in exercises off Norway. On 25 August, she suffered an explosion in one of her batteries, caused by an electrical fire that had been triggered during a polar gale. Despite all efforts, the crew was unable to save their ship when a second battery exploded fourteen hours later. All but one of the crew was rescued by the USS Tusk, at a cost of six of Tusk's own, and Cochino became the first of four US submarines lost after World War II.
