The USS Triton (SS-201) was a Tambor-class submarine commissioned into the United States Navy in August 1940. Constructed at the Portsmouth Navy Yard, her keel was laid on July 5, 1939, and she was launched on March 25, 1940. She measured approximately 311 feet in length, with a beam of about 27 feet, and was powered by diesel engines capable of reaching speeds around 21 knots on the surface and 9 knots submerged. Her armament included torpedo tubes and deck guns, making her a versatile combat vessel. Triton’s wartime service primarily took place in the Pacific theater. She completed five patrols over 14 months, during which she sank over 20,000 tons of Japanese shipping and warships. Her patrols included operations off Wake Island, the East China Sea, Alaskan waters, and the Truk–Rabaul–New Guinea shipping lanes. Notable actions include launching the first American torpedoes shot during World War II, sinking enemy ships such as Shinyo Maru Number 5, Taei Maru, and Calcutta Maru, and the first confirmed sinking of an enemy vessel by deck gun fire by an American submarine, when she sank the Japanese trawler near Marcus Island. Trition's patrols were marked by aggressive engagement, including numerous torpedo attacks on convoys and enemy vessels. She also played a role in the Battle of Midway and supported operations near Wake Island, including guiding bombers and attacking enemy ships. Her last patrol began in mid-March 1943, but she was lost with all hands around March 15, 1943, after being attacked by Japanese destroyers. Post-war records confirmed her sinking, and she was awarded five battle stars for her service. Her ship’s bell, not aboard at the time of her loss, was recovered in 2011 and is now displayed at Naval Station Great Lakes. Triton remains a significant example of early U.S. submarine warfare in WWII, recognized for her active combat record and contributions to the Pacific campaign.
