• USS Sea Cat (SS/AGSS-399) was a Balao-class submarine that served in the United States Navy during World War II and the early years of the Cold War. • Construction and Commissioning: Sea Cat was laid down on 6 October 1943 by Portsmouth Navy Yard, launched on 21 January 1944, and commissioned on 16 March 1944. • War Patrols: During World War II, Sea Cat conducted a total of five war patrols, primarily in the Pacific Theater, including the South China Sea and the Philippine Islands area. • Combat Record: Although she did not sink any enemy ships, Sea Cat contributed to the war effort by rescuing downed aviators and disrupting Japanese shipping through reconnaissance and lifeguard duties. • Post-War Service: After World War II, Sea Cat was decommissioned and placed in reserve, but was later modernized and recommissioned in 1951 as an auxiliary research submarine (AGSS-399). • GUPPY Conversion: Sea Cat received the GUPPY II conversion, which upgraded her with snorkel systems, improved batteries, and a streamlined hull for greater underwater performance, reflecting Cold War technological advancements. • Scientific Research: In her later years, Sea Cat participated in various experimental missions and research activities, including sonar testing and anti-submarine warfare exercises. • Home Ports: Throughout her service, Sea Cat was based at several different ports, including Key West, Florida, which was an important hub for submarine operations and training during the Cold War. • Decommissioning and Fate: USS Sea Cat was finally decommissioned on 2 December 1968 and struck from the Naval Vessel Register in 1971. She was sold for scrap in 1973. • Legacy: While not as famous as some of her sister ships, the Sea Cat represents the adaptability and longevity of the Balao-class submarines, serving in both combat and research roles for nearly three decades.
