The USS Conestoga (AT-54), originally constructed in 1904 by the Maryland Steel Company in Sparrows Point, Maryland, was a robust ocean-going tug designed for various towing and support roles. Initially built for the Philadelphia and Reading Railway and named Conestoga, the vessel was acquired by the U.S. Navy on 14 September 1917, during World War I, and commissioned on 10 November 1917. She was designated with the Section Patrol number SP-1128 and later received the hull number AT-54 in July 1920. Constructed as a steel-hulled vessel, the Conestoga served primarily along the Atlantic coast, undertaking towing duties, transporting supplies and guns, and escorting convoys to Bermuda and the Azores. She also operated with the American Patrol Detachment near the Azores, contributing to wartime maritime security. Following the end of World War I, she was assigned to Naval Base No. 13 in the Azores, where she continued towing disabled ships and escorting vessels until arriving in New York on 26 September 1919. Subsequently, she was reassigned to harbor tug duties in the 5th Naval District at Norfolk, Virginia. In late 1920, the Conestoga was transferred to the Pacific Fleet, with operations based in San Diego and Mare Island. On 25 March 1921, under the command of Lt. Ernest Larkin Jones, she set sail from Mare Island, heading towards Tutuila, American Samoa, with a barge of coal via Pearl Harbor. She was assigned to serve as a station ship at Tutuila, but she was never heard from again after her departure. Despite extensive searches, only a lifeboat bearing her initials was found near Manzanillo, Mexico. Her final resting place was unknown until 2009, when her wreck was discovered in the Greater Farallones National Marine Sanctuary, near San Francisco, California. Confirmed as the USS Conestoga in 2015 through joint NOAA and Navy investigations, the shipwreck was officially listed on the National Register of Historic Places in 2016, marking her maritime significance and the enduring interest in her story.
