USS Torsk

USS Torsk was a Tench-class submarine of the United States Navy commissioned during World War II that gained distinction for sinking the last enemy warship by the United States in that conflict. Built at the Philadelphia Naval Shipyard and serving in the Pacific War, she later joined the postwar fleet during the early Cold War before becoming a preserved museum ship in Baltimore, Maryland. Torsk remains notable for her survival into the 21st century and for educational displays related to submarine warfare, naval architecture, and World War II naval operations.

Design and construction

Torsk was laid down and launched by the Philadelphia Naval Shipyard, a major shipbuilding facility tied to Naval Shipyards of the United States and wartime industrial mobilization programs under the United States Navy expansion. As a member of the Tench-class submarine type, she followed design evolution from the earlier Gato-class submarine and Balao-class submarine, incorporating improvements in hull strength, internal arrangements, and habitability driven by wartime patrol experience. Her diesel-electric propulsion reflected standards used across the United States submarine force in the 1940s, with battery capacity and quieting measures influenced by doctrine developed by Submarine Force, United States Pacific Fleet commanders. Construction reflected training and labor drawn from unions and workforce programs associated with Philadelphia and technical oversight by the Bureau of Ships.

Service history

After commissioning in 1944, Torsk completed shakedown and proceeded to the Pacific Ocean theater, joining operations that linked to campaigns such as the Marianas campaign and the island-hopping drive toward Japan. On 14 July 1945, while operating off the Bungo Strait approaches, her crew fired torpedoes that sank a Japanese coastal destroyer in actions tied to late-war interdiction of Imperial Japanese Navy movements; this sinking has been recorded as the last enemy warship sunk by the United States during World War II. Her patrols involved reconnaissance, convoy interdiction, and lifeguard duties supporting aviators from carriers like USS Saratoga (CV-3) and USS Enterprise (CV-6), reflecting joint operations between the United States Pacific Fleet and the Fifth Fleet (United States). Post-surrender, Torsk participated in occupation-era activities and returned to the United States for overhaul and reassignment, interfacing with commands such as Submarine Squadron 2 and training establishments at New London, Connecticut.

During the early Cold War, Torsk undertook training cruises, antisubmarine warfare exercises with surface units including escorts from Destroyer Squadron 24, and reserve training that linked to the Naval Reserve program. She operated alongside contemporaries such as USS Nautilus (SS-168) and later diesel boats in mixed-force evolutions, reflecting changing tactics as nuclear propulsion emerged with USS Nautilus (SSN-571) and sonar developments influenced by advances at institutions like Naval Research Laboratory.

Post-war career and museum ship

Decommissioned to reserve status in 1959 and struck in 1968, Torsk was preserved through efforts by civic and veterans' organizations in Maryland and the city of Baltimore. She was towed to the Baltimore Inner Harbor and opened as a museum ship, administered in partnership with municipal agencies and nonprofit groups including local chapters of United States Submarine Veterans and historical societies. As a museum, Torsk became integrated with attractions like the National Aquarium (Baltimore) and the Maryland Science Center, contributing to maritime heritage tourism and educational programming about World War II and Cold War naval history. Her public berth enabled veterans’ reunions, school visits, and artifact conservation projects led by curators versed in maritime archaeology and preservation techniques used at other preserved vessels such as USS Constitution and USS Midway (CV-41).

Characteristics and armament

Torsk retained the Tench-class standard armament suite: ten 21-inch bow and stern torpedo tubes supplied from a complement of torpedoes managed under ordnance procedures of the Bureau of Ordnance; a 5-inch/25 caliber deck gun similar to mounts aboard other fleet submarines; and various anti-aircraft weapons for surface defense, comparable to fits on Balao-class submarine boats. Her propulsion consisted of diesel engines driving electric generators and motors, with battery banks enabling submerged endurance typical of conventionally powered boats before nuclear propulsion adoption. Habitability and sensor suites reflected wartime upgrades: improved periscopes from manufacturers contracting with the Navy, sonar arrays influenced by work at Office of Naval Research, and radio/cryptographic equipment interoperable with carrier and fleet command networks in the Pacific Fleet.

Legacy and cultural significance

Torsk’s legacy is preserved through museum interpretation, commemoration by veterans associated with the United States Submarine Veterans organization, and inclusion in discussions of final engagements of World War II naval history. As a tangible link to submarine service, she features in curricula about naval strategy taught at institutions like the United States Naval Academy and in exhibitions curated by state historical commissions and maritime museums. Her survival alongside other preserved warships informs public memory of the Imperial Japanese Navy conflict and the evolution from diesel-electric to nuclear submarines epitomized by vessels such as USS Nautilus (SSN-571). Through outreach and conservation, Torsk continues to connect contemporary audiences to the experiences of submariners, shipbuilders from Philadelphia, and the broader industrial and operational networks of mid-20th-century naval history.
