Portsmouth Naval Shipyard

Portsmouth Naval Shipyard's primary mission is the overhaul, repair and modernization of Los Angeles-class submarines. Portsmouth Naval Shipyard provides the U.S. Navy's nuclear-powered submarine fleet with quality overhaul work in a safe, timely and affordable manner. This includes a full spectrum of in-house support--from engineering services and production shops, to unique capabilities and facilities, to off-site support--all of which serves the multifaceted assortment of fleet requirements. With the commissioning of the Virginia-class submarine, USS New Hampshire (SSN 778) in 2008, the shipyard and the Seacoast Communities got their first look at the next generation of submarine technology and the future of ship repair. Portsmouth Naval Shipyard is performing the first extended availability on the new class of submarine on USS Virginia (SSN 774) which began October 1, 2010. Portsmouth Naval Shipyard is focused on servicing the needs of the fleet and remains "Proud of our past . . . Ready for the future."
