AP reported that the attack submarine USS Salt Lake City arrived Thursday at the Portsmouth Naval Shipyard, which will serve as its last stop before the submarine is dismantled and scrapped. The Salt Lake City and its 127-member crew completed its career by surfacing through the polar ice cap, breaking through more than a foot of snow near the North Pole on Nov. 17, before making its way to the shipyard on the Maine-New Hampshire border. The sub will spend about a year in Kittery, undergoing defueling and other steps in the inactivation process, said shipyard spokeswoman Deb White. After that, it will be towed back to the West Coast, to the Puget Sound Naval Shipyard in Bremerton, Wash., where it will be recycled, she said. A deactivation ceremony for the 360-foot-long sub was held in October in San Diego. The warship was commissioned in 1984 at Norfolk, Va.
