USS Memphis (SSN 691) was built by Newport News Shipbuilding and Drydock Company. Commissioned Dec. 17, 1977, it became an Atlantic Fleet operational asset as part of Submarine Squadron EIGHT in Norfolk, Va. in 1978. In March 1981, USS Memphis completed a "round-the-world" cruise via the Panama Canal, including operations with both the Sixth and Seventh fleets.

In January 1994, Memphis entered Portsmouth Naval Shipyard for refueling overhaul and equipment modifications providing the world's most advanced sonar, signal processing and fire control technology. Several modifications were performed to enhance the ship's ability to accommodate major and multiple research and development projects. Upon completion of overhaul in July 1996, Memphis was attached to Submarine Development Squadron Twelve in Groton, Conn.

The ship and its crew represent the Navy's significant effort to meeting our nation's worldwide operational commitments while developing tomorrow's technologies in an affordable and efficient manner. This unique and dynamic capability ensures the earliest introduction of promising technologies to the submarine fleet today while setting the course for the submarine force of tomorrow.
