The USS New Hampshire (SSN-778) is a Virginia-class nuclear-powered attack submarine, notable as the first of the Block-II submarines to enter service. Named after the state of New Hampshire, this vessel represents a significant advancement in naval technology and submarine design. The ship’s construction was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, with work beginning in January 2004. The keel was laid on 30 April 2007 at Electric Boat’s Quonset Point facility in North Kingstown, Rhode Island, marking the formal start of construction. The submarine was launched on 21 February 2008 and was christened four months later, on 21 June 2008, in Groton, Connecticut. Its launch was eight months ahead of schedule and came in $54 million under budget, showcasing efficient project management. After completing sea trials, USS New Hampshire was delivered to the U.S. Navy on 28 August 2008. She was officially commissioned on 25 October 2008 at the Portsmouth Naval Shipyard in Kittery, Maine. The vessel’s sponsor was Cheryl McGuinness, the widow of Thomas McGuinness, a co-pilot killed in the September 11, 2001 attacks. The submarine has played a vital role in naval operations, including an incident in March 2011 when she suffered an oxygen generator failure during an Arctic mission. The crew managed to surface through the ice using oxygen candles, and a response team was dispatched to repair the system, highlighting her operational versatility and resilience. As a modern nuclear attack submarine, USS New Hampshire embodies technological innovation, strategic capability, and maritime significance for the U.S. Navy, carrying on the legacy of the vessels bearing the name and contributing to national defense through advanced stealth, endurance, and combat readiness.
