Pawtucket's entire career was spent on the Pacific coast, active in the 13th Naval District, the Puget Sound Navy Yard being her permanent base for more than thirty years. During World War II she was armed with a single 20 mm gun and served as a patrol craft and minesweeper in the Puget Sound area, with an increased complement of 16. Pawtucket was redesignated "YTM-7" on 15 May 1944.
