USS Hartford (SSN-768)

USS Hartford (SSN-768), a Los Angeles-class submarine, is the second ship of the Navy to be named for Hartford, Connecticut. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 30 June 1988 and her keel was laid down on 22 February 1992. She was launched on 4 December 1993 sponsored by Laura O'Keefe, wife of former Secretary of the Navy Sean O'Keefe, and commissioned on 10 December 1994, with Commander George Kasten in command.

In October 2007, the submarine successfully launched and recovered an AN/BLQ-11 unmanned underwater vehicle (UUV), the first such operation from a submarine. The vehicle was launched via one of the boat's torpedo tubes and recovered with the help of a 60-foot robotic arm.

2003 grounding in Sardinia
On 25 October 2003 Hartford ran aground near La Maddalena in Sardinia with such force that rudders, sonar and other electronic equipment were severely damaged. After the accident Commander Christopher R. Van Metre, captain of Hartford, and Captain Greg  Parker, Commodore of Submarine Squadron 22, were relieved of command and sent back to the United States. Six other crewmen were also charged with dereliction of duty.

2009 collision in Strait of Hormuz
On 20 March 2009 Hartford collided with amphibious transport dock USS New Orleans (LPD-18) in the Strait of Hormuz, slightly injuring 15 sailors on board. Both vessels were able to proceed under their own power after the incident, although the New Orleans suffered a ruptured fuel tank, releasing 25,000 gallons of diesel fuel into the strait.

The Navy announced on 14 April 2009 that the submarine's skipper, Commander Ryan Brookhart, had been relieved of duty by Rear Admiral Michael J. Connor because of a loss of confidence in Brookhart's ability to command. Brookhart was replaced by Commander Chris Harkins, deputy commander of Submarine Squadron Eight.

A repair contract has been awarded to General Dynamics. Repairs were initially expected to cost $37.4 million and be completed by January 2010. However, as of November 2009, repair costs had already exceeded $100 million. Final repair cost was $120 million when Hartford returned to duty in February, 2011
