Ingalls Shipbuilding is a shipyard located in Pascagoula, Mississippi, United States, originally established in 1938, and now part of HII.
It started out building commercial ships, including USS George Clymer, which took part in Liberty Fleet Day on 27 September 1941.
In the 1950s, Ingalls started bidding on Navy work, winning a contract in 1957 to build 12 nuclear-powered attack submarines.
While shipbuilding was halted for a while due to the destruction of many buildings, most vehicles and the large overhead cranes are the same that the facility continues to operate today.
In 2015, Ingalls Shipbuilding Company signed a contract with US Navy for new destroyers, littoral combat ships, and new landing craft.
On 21 March 2015, the new San Antonio-class amphibious transport dock ship USS John P. Murtha was ceremonially christened.
