our history


On March 31, 2011, Huntington Ingalls Industries (HII) formed as an independently, publicly traded company when two legacy shipyards joined forces to become the nation’s largest shipbuilder. Since then, HII’s portfolio expanded further with the establishment of a third division that delivers all-domain technology solutions to civil, commercial, and defense customers both domestically and internationally.

Today HII is a global, all-domain defense provider with a more than $45B shipbuilding backlog and more than 44,000 employees. It is the largest industrial employer in both Virginia, where the company is headquartered, and in Mississippi. The company’s name derives from the founders of its shipbuilding divisions: Collis Potter Huntington, who founded Newport News Shipbuilding and Drydock Company, and Robert Ingersoll Ingalls Sr., who established Ingalls Shipbuilding.


Since 1886, the ships built at Newport News Shipbuilding, like the American Shipbuilders who built them, have served our nation in peace and war, in times of adversity and times of abundance. HII’s legacy of “Always Good Ships” includes the design, construction, overhaul and repair of hundreds of ships for the U.S. Navy and commercial customers.

Today, NNS, a division of HII, is the nation’s sole designer, builder and refueler of nuclear-powered aircraft carriers and one of only two shipyards capable of designing and building nuclear-powered submarines, leveraging our unique expertise in nuclear propulsion, naval design and manufacturing. NNS provides fleet services for our ships worldwide.


In 1938, Ingalls Shipbuilding Corporation was founded by Robert Ingersoll Ingalls Sr. (1882–1951), on the East Bank of the Pascagoula River in Mississippi. It started out building commercial ships until the 1950s, when Ingalls started bidding on Navy work.

Today, Ingalls Shipbuilding, a division of HII, has pioneered the development and production of technologically advanced, highly capable warships for the surface Navy fleet, U.S. Coast Guard, U.S. Marine Corps, and foreign and commercial customers.

Mission Technologies was founded in 2016 as HII’s third division. Mission Technologies develops integrated solutions that enable today’s connected, all-domain force. Capabilities include C5ISR systems and operations; the application of AI and machine learning to battlefield decisions; defensive and offensive cyberspace strategies and EW; unmanned autonomous systems; LVC solutions; fleet modernization; and critical nuclear operations. HII’s Mission Technologies division is headquartered in McLean with more than 100 facilities across the globe.
