USS Memphis (SSN-691), a Los Angeles-class submarine, was the sixth ship of the United States Navy to be named for Memphis, Tennessee. The contract to build her was awarded to Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia on 4 February 1971 and her keel was laid down on 23 June 1973. She was launched on 3 April 1976 sponsored by Mrs. Cathy Beard, and commissioned on 17 December 1977, with Commander G. Dennis Hicks in command.
In March 1981, Memphis completed an around-the-world cruise via the Panama Canal, including operations with both the Sixth and Seventh Fleets.
Memphis was redesignated an experimental submarine during 1989 to test composite hull structures, unmanned underwater vehicles, advanced sonars, hull friction reduction, and other advanced technologies for the Los Angeles and Seawolf classes, but remained combat-capable.
During a mid-1990s refit, Memphis received numerous modifications, which added about 50 tons to her displacement, most of it aft.
In January 1994 Memphis entered Portsmouth Naval Shipyard for refueling, overhaul and modifications to support her research and development role. Upon completion of the shipyard availability she was assigned to Submarine Development Squadron 12 in Groton, Connecticut.
In 1998 Memphis tested the Lockheed Martin Undersea Systems Universal Gravity Module (UGM) passive bottom profiler navigational system.
On 3 May 2005, Memphis deployed conducting two polar transits, returning to New London on 3 November 2005.
