USSAlexandria (SSN-757), is aLos Angeles classnuclear-poweredattack submarine and the third vessel of theUnited States Navy to be named for bothAlexandria, Virginia, andAlexandria, Louisiana.[2] The contract to build her was awarded to theElectric Boat Division ofGeneral Dynamics Corporation on 26 November 1984. Herkeel was laid down inGroton, Connecticut, on 19 June 1987.[11] She waslaunched on 23 June 1990, sponsored by Mrs. Myrtle "Tookie" Clark, wife ofVice AdmiralGlenwood Clark (ret.), and commissioned on 29 June 1991.[1]Alexandria was placed in service on 22 March 1991. A series of sea trials began 16 April and were completed 4 June.[1]
Alexandria, together with the guided-missilecruiserUSS Cowpens (CG-63), guided-missilefrigateUSS Gary (FFG-51), andP-3C Orion maritime patrol and reconnaissance aircraft, participated inExercise Malabar 2004, a training exercise with theIndian Navy off the southwest coast of India that ended on 11 October 2004.
In March 2007Alexandria was participating in the joint U.S. Navy/Royal Navy Ice Exercise 2007 (ICEX-2007), conducted in theArctic Ocean with theTrafalgar-classsubmarineHMS Tireless (S88). The exercise took place on and under a driftingice floe, about 180 nmi (330 km; 210 mi) off the north coast ofAlaska. The two submarines were taking part in joint testing of submarine operability and tactical development in Arctic waters. On 21 March 2007,Tireless experienced an explosion of a self-containedoxygen generation candle, she suffered only superficial damage, but two crew members were killed and one injured.[12]
Some scenes for the movieStargate: Continuum were filmed on boardAlexandria. The then-captain ofAlexandria, Commander Mike Bernacchi, and members of his crew played themselves. The ship was also used as a filming location for theJAG andNCIS TV series, although she was referred to there as the fictionalUSSCathedral City.[13]

The submarine was traveling in excess of 33 knots -- about 35 mph --when its nose hit the undersea formation head-on, officials said.
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.
