Huntington Ingalls Industries (HII) is the largest military shipbuilding company in the United States and a global, all-domain defense provider. Formed on March 31, 2011, as a divestiture from Northrop Grumman, HII comprises three core divisions: Newport News Shipbuilding in Virginia, Ingalls Shipbuilding in Mississippi, and Mission Technologies. The company leverages over 140 years of shipbuilding heritage to deliver the world’s most powerful and survivable naval ships, including nuclear-powered submarines, aircraft carriers, and amphibious warships.

HII’s Mission Technologies division develops integrated, all-domain solutions that enable connected defense forces, with capabilities spanning C5ISR systems, AI and machine learning for battlefield decisions, cyber strategies, electronic warfare, unmanned systems, and fleet modernization. The company serves the U.S. Navy, Coast Guard, and international partners, maintaining a shipbuilding backlog exceeding $45 billion and employing more than 44,000 people globally.

Headquartered in Newport News, Virginia, HII is united by a mission to protect peace and freedom through engineering excellence and national service. Its legacy shipyards—Newport News Shipbuilding (founded 1886) and Ingalls Shipbuilding (founded 1885)—form the foundation of its enduring contribution to U.S. national defense.
