The Portsmouth Naval Shipyard, often called the Portsmouth Navy Yard, is a United States Navy shipyard located in Kittery on the southern boundary of Maine near the city of Portsmouth, New Hampshire. PNS is tasked with the overhaul, repair, and modernization of US Navy submarines.
The Portsmouth Naval Shipyard was established on June 12, 1800 during the administration of President John Adams, and is the U.S. Navy's oldest continuously operating shipyard. It sits on a cluster of conjoined islands called Seavey's Island in the Piscataqua River, whose swift tidal current prevents ice from blocking navigation to the Atlantic Ocean.
