This legendary submarine fired the final naval shots of World War II.
Commissioned in December 1944, the Tench-class fleet submarine USS Torsk (SS-423) reached the Pacific theater just in time to write the closing chapter of the naval war. On August 13, 1945, while patrolling off the coast of Japan, Torsk torpedoed and sank a Japanese cargo vessel. The following morning, August 14, her crew deployed new, experimental Mark 28 acoustic homing torpedoes, destroying two Japanese coastal defense frigates, including Kaibōkan No. 47, making it the final enemy warship sent to the bottom by the United States Navy in World War II. Hours later, Japan announced its unconditional surrender, cementing Torsk’s unique place in military history after completing just two war patrols.
Following the war, the submarine embarked on a remarkably active two-decade career. Converted to a Fleet Snorkel submarine in 1952, Torsk participated in NATO exercises, Mediterranean deployments, and the naval blockade during the 1962 Cuban Missile Crisis before her decommissioning in 1968. Over her operational life, she logged more than 10,600 dives, among the highest totals in U.S. Navy history. In 1972, the warship arrived at Baltimore's Inner Harbor, where she remains open to the public as a National Historic Landmark. Instantly recognizable by the iconic, wide-grinning shark's teeth painted across her bow, Torsk stands today as a preserved museum ship, offering visitors an intimate look into the world of the crew who closed out the war beneath the waves.
