USS Torsk (SS-423)

Moored amid Baltimore’s Inner Harbor, USS Torsk (SS-423) presents a late-war Tench-class submarine preserved essentially in the configuration that closed out the Pacific campaign. Built at Portsmouth Navy Yard and commissioned in December 1944, Torsk represents the final evolution of the Gato–Balao design lineage, with refinements born of hard lessons from earlier patrols. Her hull, measuring just over 311 feet with ten 21-inch torpedo tubes, embodies the balance between range, firepower, and underwater endurance that defined U.S. fleet submarines. Torsk’s two 1945 patrols off Japan culminated in sinking coastal defense frigates, including the last enemy warship destroyed by the U.S. Navy in World War II on 14 August 1945. Postwar, she shifted to training duties, supporting Atlantic Fleet anti-submarine warfare development and later Naval Reserve instruction before transfer to Maryland as a museum ship. In an urban waterfront setting rather than a naval base, the boat highlights both the technical sophistication of mid-20th-century undersea warfare and the preservation challenges of maintaining a complex combat vessel far from its original operational environment.
