NotesThe third ship of the United States Navy to be named for both Alexandria, Virginia, and Alexandria, Louisiana

USS Alexandria (SSN-757), is a Los Angeles class nuclear-powered attack submarine and the third vessel of the United States Navy to be named for both Alexandria, Virginia, and Alexandria, Louisiana.[1] The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation on 26 November 1984. Her keel was laid down in Groton, Connecticut, on 19 June 1987.[10] She was launched on 23 June 1990, sponsored by Mrs. Myrtle "Tookie" Clark, wife of Vice Admiral Glenwood Clark (ret.), and commissioned on 29 June 1991.[2] Alexandria was placed in service on 22 March 1991. A series of sea trials began 16 April and were completed 4 June.[2]

The 18 SSN-688 class submarines that will be refueled at their mid-life could make good candidates for a service life extension because they could operate for nearly 30 years after the refueling. After these submarines serve for 30 years, they could undergo a 2-year overhaul and serve for one more 10-year operating cycle, for a total service life of 42 years.
