The USS Patapsco (Fleet Tug No. 10, later AT-10) was a steel-hulled, two-masted fleet tug constructed for the United States Navy, serving from 1909 to 1925. Built at the Portsmouth Navy Yard in Kittery, Maine, she was laid down on April 15, 1907, launched on June 29, 1908, and commissioned on July 27, 1909. Her design featured a robust, sea-going steel hull suited for her primary role as a tender and support vessel for the Atlantic Fleet. Throughout her service, Patapsco operated along the eastern seaboard, initially supporting the Atlantic Fleet. With the advent of World War I, her duties expanded significantly. She assisted Mine Squadron 1 with mine planting and experimental activities related to mine warfare. In November 1917, she played a vital role in training seamanship and mine handling personnel at Newport, Rhode Island, in preparation for extensive mine barrage operations across the North Sea. In 1918, Patapsco escorted submarine chasers to Brest, France, and later to Naval Base 18 in Inverness, Scotland, where she remained for the duration of the war, inspecting minefields and maintaining communications between mine bases. After the war, she participated in experiments to develop mine sweeping gear and techniques, including testing electrical mine exploders in 1919. During these operations, she experienced a notable explosion when she inadvertently detonated a low-level countermined mine, causing significant damage but allowing her to continue service. Post-war, she continued minesweeping operations in the North Sea, until November 1919, when she returned to the United States. Her peacetime duties included a tour in the First Naval District at Boston and service as a tender in Santo Domingo until 1924. She was decommissioned at Norfolk on January 16, 1925, and remained in reserve until she was stricken from the Navy List in 1936. Her hull was sold for scrapping in June 1936, though she remained intact at the scrapyard into 1940, with her ultimate scrapping believed to have been completed by 1941. The USS Patapsco's service highlights her role in early 20th-century mine warfare and naval logistics, contributing to both wartime operations and experimental mine countermeasures.
