USS Triton

Five ships and submarines of the United States Navy and United States Coast Guard have been named USS Triton, for Triton, a Greek demigod of the sea who was the son of Poseidon and Amphitrite.

• The first USCGC Triton was a 165 foot (50 m) cutter which operated out of United States Coast Guard Base 15 at Biloxi, Mississippi during what was referred to at the time as "the Prohibition War"—operations against alcohol smugglers during Prohibition.

• The second USS Triton (YT-10), a 212-ton tug, was built at Camden, New Jersey, in 1889 and purchased in that year by the United States Navy. Her long career was spent operating out of the Washington Navy Yard with frequent trips to Indian Head, Maryland. In 1921, she was designated YT-10. Triton was struck from the Naval Vessel Registry in May 1930 and sold the following September.

• The third USS Triton (SS-201) was a Tambor-class submarine commissioned in 1940 and sunk in 1943 during World War II.

• The fourth USCGC Triton (WPC/WMEC-116) was a United States Coast Guard patrol boat that was commissioned in 1934 and served until 1967.

• The fifth USS Triton (SSRN/SSN-586), a nuclear-powered radar picket submarine, was commissioned in 1959 and struck in 1986. She was the first vessel to execute a submerged circumnavigation of the Earth.
