The USS Perch (SS/SSP/ASSP/APSS/LPSS/IXSS-313) was a Balao-class submarine constructed for the United States Navy during World War II. Laid down on January 5, 1943, by the Electric Boat Company in Groton, Connecticut, she was launched on September 12, 1943, and commissioned on January 7, 1944. The vessel measured approximately 311 feet in length with a beam of about 27 feet, typical of Balao-class submarines, designed for both combat and reconnaissance missions. Initially serving in the Pacific Theater, Perch’s wartime operations included multiple patrols in the South China Sea, East China Sea, and around the Philippines. Her first patrol commenced in April 1944, during which she engaged enemy shipping, notably damaging a medium tanker with torpedoes. She continued her combat missions with success, sinking a Japanese trawler and supporting B-29 bombing raids by performing lifeguard duties off Japan. Noteworthy was her fifth patrol, during which she carried special operatives and engaged in reconnaissance and sabotage in Borneo, including sinking a coastal freighter after contact with Japanese patrols. Post-World War II, Perch transitioned to a troop- and cargo-carrying role, being redesignated as SSP-313 in 1948 and later as ASSP-313 in 1950. She participated in various exercises, including transporting commandos during the Korean War, where her commanding officer received a Bronze Star for combat action. The vessel was fitted with experimental equipment, such as a large hangar for helicopters and amphibious craft, to test new capabilities for reconnaissance and special operations. Throughout the 1950s and 1960s, USS Perch served as a training and reconnaissance platform, operating in the Pacific, conducting amphibious exercises, and supporting special forces in Vietnam. Her activities included landing reconnaissance teams, supporting covert operations, and participating in joint exercises with allied nations. She was reclassified multiple times, reflecting her evolving roles, until she was decommissioned on December 1, 1971, and sold for scrapping in 1973. The USS Perch’s service highlights her versatility and significance in both wartime combat and Cold War reconnaissance and special operations.
