The USS Concord (SP-773) was a versatile U.S. Navy tugboat constructed in 1898 by Charles Hillman in Philadelphia, Pennsylvania. Originally built for civilian purposes, she was acquired by the Navy on 22 September 1917 during World War I and was commissioned on 20 November 1917. Throughout her service life, she underwent several name changes, being renamed USS Mendota (YT-33) on 20 November 1920, and later USS Muscotah (YT-33) on 30 January 1932. Concord’s early wartime duties involved towing operations, beginning with a voyage from Philadelphia on 15 December 1917 to Bermuda. There, she joined vessels Galatia and Gypsum Queen to tow three French submarine chasers to Ponta Delgada in the Azores. From this strategic location, she proceeded to Brest, France, arriving on 22 February 1918. During her tenure in European waters, she served primarily as a harbor tug, assisting with the movement and docking of ships until 25 October 1919. After returning to the United States, Concord arrived at Norfolk, Virginia, on 28 November 1919. The following month, she reported to the Washington Navy Yard, where she was placed "in service" as a harbor tug, supporting naval operations within the harbor. Her service continued until she was placed out of service on 4 November 1934. Subsequently, she was sold on 30 April 1937. Throughout her career, USS Concord played a vital role in towing and harbor support during a significant period of naval activity, including World War I. Her reclassifications and renaming reflect the evolving roles and administrative changes within the Navy, and her service history highlights her importance as a reliable auxiliary vessel in both wartime and peacetime operations.
