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 February 1993 Memphis ran aground offshore of Dania Beach, Florida.[2] The grounding caused physical damage to the reef substrate and biological damage to the coral community, which was of the Holocene era and with no recent framework growth over 6,000 years. The State of Florida sued the U.S. Navy for $2.4 million, and was awarded $750,000 for mitigation and repairs.[3]
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.[4]
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.
Memphis won the coveted Battenberg Cup in 2005, as well as the Squadron 12 Battle E.
On 6 May 2006, Memphis deployed against Iraqi insurgency, returning to New London, Connecticut, on 7 August.
On 27 June 2007, Memphis returned to Portsmouth Naval Shipyard in Kittery, Maine, for a Pre-Inactivation Restricted Availability. She returned to Groton on 8 May 2008.
After 33 years of service Memphis was taken out of service in a decommissioning ceremony at the Shepherd of the Sea Chapel located at the US Submarine Base in Groton, Connecticut on 1 April 2011. Memphis went to the Portsmouth Naval Shipyard to begin the inactivation process.[5][6]
Parts from the decommissioned Memphis were to be used to repair the damaged USS Miami,[7] until the decision to cease work on Miami was made in August 2013.
In November 2010, Navy investigators discovered rampant cheating taking place on training exams among the sub's crew. The sub's skipper, Commander Charles Maher was removed. Thirteen other crewmembers were also removed. Navy officers interviewed by the Associated Press stated that training exam cheating was widespread within the Navy's submarine force.[8]
