USS New Hampshire (SSN-778), a Virginia-class nuclear-powered attack submarine, is the fourth ship of the United States Navy to be named for the state of New Hampshire (though one of her predecessors, BB-70, existed only on paper – authorized, but cancelled before keel laying). She is the first of the Virginia Block II submarines to enter service. Her name was awarded to the submarine after a letter-writing campaign by the third-graders from Garrison Elementary School in Dover to their members of Congress, the state governor, and the Secretary of the Navy.[4]

The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 14 August 2003. Construction began in January 2004.[5] A keel-laying ceremony for the submarine was held at Electric Boat's Quonset Point facility in North Kingstown, Rhode Island, on 30 April 2007. The ship's sponsor was Cheryl McGuinness of Portsmouth, New Hampshire, the widow of Thomas McGuinness, co-pilot of American Airlines Flight 11, who died in the September 11, 2001 attacks when the jet was flown into the North Tower of the World Trade Center.[6]

The submarine was launched on 21 February 2008 and christened four months later, on 21 June 2008 in Groton, Connecticut, eight months ahead of schedule and $54 million under budget.[2][7] New Hampshire finished sea trials and was delivered to the Navy on 28 August 2008.[8] The ship was commissioned in a ceremony at the Portsmouth Naval Shipyard in Kittery, Maine, on 25 October 2008.[9]

Incidents aboard New Hampshire

During the week of 13 March 2011, while on a mission under the Arctic ice cap, New Hampshire suffered an oxygen generator failure. This failure required the ship to surface through the ice. The crew had used oxygen candles to make oxygen until the ship surfaced. United Technologies Corp., the company responsible for building the oxygen generator, had dispatched a representative with needed replacement parts to the submarine by way of a temporary ice camp, to assist the ship's crew in repairing the problem.[10]
