Portsmouth Naval Shipyard at a glance
Portsmouth Naval Shipyard overhauls, repairs and modernizes the U.S. Navy's nuclear-powered attack submarines. Its officially identified work includes Los Angeles and Virginia-class submarines. The mission draws on engineering services, production shops and specialized facilities, with a substantial civilian technical workforce supporting the fleet's industrial maintenance needs.
Despite its name, the shipyard is in Kittery, Maine, on Seavey Island at the mouth of the Piscataqua River, across the harbor from Portsmouth, New Hampshire. Its history spans early warship construction, submarine building and the later transition to overhaul work. The local Seacoast community crosses the Maine-New Hampshire state line. The official installation profile identifies limited island parking, making the actual island workplace important when assessing nearby communities and commuting options.
