The Fulton class was a class of seven United States Navy submarine tenders. The class took its name from the lead ship, , which was commissioned 27 December 1940 by Mare Island Navy Yard and sponsored by Mrs. A. T. Sutcliffe, great-granddaughter of Robert Fulton. Fulton was commissioned on 12 September 1941. The basic hull and superstructure for this class was the same as the Dixie-class destroyer tenders and Vulcan-class repair ships.
In 1959-1960, Proteus was converted to a tender for the Polaris Fleet Ballistic Missile submarines, including the addition of a 13.4 m section amidships. All ships of this class have been decommissioned and scrapped.
