Proud of our past...
Ready for the future
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.
Mission: We are Portsmouth. Together we are honor bound to support and defend the Constitution of the United States. We do so proudly by maintaining, repairing and modernizing our Navy’s submarines so that they can go in harm’s way, defeat our enemies in war and return their crews home safely.
Vision: People love to work at Portsmouth. Their passion, dedication, innovation and unified effort ensure we will always be the Navy’s Center of Excellence for submarine maintenance.
Values: We define Portsmouth every day through our service. With this service comes great responsibility; to our families, to each other, to our heritage, and to our Nation. We meet these responsibilities by living up to the values embodied in our Declaration of Excellence and the Navy’s core values of honor, courage, and commitment.
