Northrop Grumman Shipbuilding

Northrop Grumman Shipbuilding Newport News, was the largest privately-owned shipyard in the United States prior to being purchased by Northrop Grumman in 2001. NGSB-NN is one of two shipyards that produce and service all types of nuclear powered submarines (the other is the Electric Boat Corporation), and at present is the only shipyard that can build supercarriers. NGSB-NN is also home to the largest crane in the western hemisphere. NGSB-NN is located in Newport News, Virginia, and often participates in projects with the Norfolk Naval Shipyard in Portsmouth, Virginia, also located adjacent to Hampton Roads.
