The USS Penguin (ASR–12) was a submarine rescue and salvage ship of the United States Navy, constructed during World War II. Originally laid down as the fleet ocean tug Chetco (AT-99) by the Charleston Shipbuilding and Dry Dock Co. in Charleston, South Carolina, she was launched on 20 July 1943. She was renamed and reclassified as USS Penguin (ASR–12) on 23 September 1943 and commissioned on 29 May 1944. Built to serve as a submarine rescue, salvage, target, and torpedo recovery vessel, Penguin was the lead ship of a class of three vessels, which included Bluebird and Skylark. After shakedown training, she reported for duty with SubRon 1 at New London, Connecticut, on 9 June 1944. Her operational duties included serving as a target and torpedo recovery ship for submarine training exercises, performing towing assignments, and participating in the planting and sweeping of experimental minefields. Notably, between April and June 1945, she conducted salvage operations on a sunken U-boat near Block Island. Penguin’s service history included a period at Portsmouth, New Hampshire, in mid-1944, where she acted as a target vessel and rescue ship during submarine sea trials. She returned to New London, serving in that area until 1946, with a brief stint off Newfoundland for cold-weather operations. In 1947, she joined the Atlantic Reserve Fleet and was decommissioned at New London on 4 September. Recommissioned on 3 April 1952, Penguin rejoined active duty with the Atlantic Fleet’s Submarine Forces, based at Key West, Florida. During her service, she conducted numerous salvage, rescue, and target recovery operations in the Caribbean and off Newfoundland. She set a record by rescuing personnel from a submarine 349 feet below the surface during training on 24 February 1955. In 1961, she became the first ASR to deploy to the Sixth Fleet in Rota, Spain. Throughout the 1960s, Penguin continued salvage and rescue operations, notably on downed aircraft and weapons tests, and served as the flagship for the Sixth Fleet’s submarine force. As of 1970, she had not been involved in any actual submarine rescue operations. Her service record highlights her importance in submarine rescue, salvage operations, and fleet support during her active years.
