USS Sea Cat (SS/AGSS-399), a Balao-class submarine, was a ship of the United States Navy named for a shortened form of sea catfish, a marine fish of little food value found off the southeastern coast of the United States commissioned on 16 May 1944, with Commander Rob Roy McGregor in command. During World War II Sea Cat operated within the Pacific theatre, conducting four war patrols in wolf packs accounting for up to 17400 tons in the form of three cargo ships and an enemy vessel (17000 tons unconfirmed by wartime Japanese records). Sea Cat earned three battle stars for her World War II service. After two and one-half years of exercises out of Balboa, her home port was changed to Key West in June 1949. In the autumn, it was decided to have a number of experimental changes made to the ship during her forthcoming overhaul, and she was redesignated AGSS-399 on 30 September. On 7 November, she arrived at the Philadelphia Naval Shipyard where the work was done. The modifications and repairs were completed on 11 March 1950, and the submarine returned, via New London, to Key West. She operated from that base until she got under way on 9 January 1952 for Philadelphia and another overhaul. After her arrival on 15 January, she was converted to a Fleet Snorkel submarine and redesignated SS-399. She operated in Floridas waters and the Caribbean until she was decommissioned on 2 December 1968 and struck from the Navy list on the same day. She was sold for scrapping, 18 May 1973. World War II service Sea Cat was laid down on 30 October 1943 by the Portsmouth Navy Yard in Kittery, Maine; launched on 21 February 1944, sponsored by Mrs. E. L. Cochrane; and commissioned on 16 May 1944, Commander Rob Roy McGregor in command. After shakedown and trials off the New England coast, the new submarine departed New London, Conn., on 28 August and proceeded via the Panama Canal to Hawaii. Following training in Hawaiian waters, Sea Cat departed Pearl Harbor on 28 October and headed, via Midway and Saipan, for the South China Sea where she operated in a wolf pack which also included , , and . During the war patrol, Sea Cat fired torpedoes at two Japanese merchantmen which, together, displaced about 15,000 tons. Her commanding officer thought that they had both been sunk, but a postwar
