Huntington Ingalls Industries,

Huntington Ingalls Industries (HII) is America’s largest military shipbuilding company and a leading provider of professional services to the U.S. government. Through its Newport News Shipbuilding and Ingalls Shipbuilding divisions, HII designs, builds, and maintains nuclear-powered aircraft carriers and submarines for the U.S. Navy, as well as surface combatants like destroyers and amphibious assault ships. The company also operates a technical solutions segment that provides fleet support, unmanned systems, and nuclear services.

HII generates revenue primarily from long-term, multi-billion-dollar contracts with the U.S. Department of Defense. Shipbuilding accounts for the vast majority of sales, with steady recurring revenue from construction programs (e.g., Ford-class carriers, Virginia-class submarines) and maintenance/refueling work. The technical solutions segment contributes about 15% of revenue through services such as logistics, training, and cybersecurity. The company’s backlog is substantial, providing multi-year visibility.

HII operates in the Aerospace & Defense industry within the Industrials sector. It is the sole builder of U.S. Navy aircraft carriers and one of only two builders of nuclear submarines, giving it a near-duopoly in its core markets. Competitors include General Dynamics (submarines and surface ships) and smaller players like Austal USA. HII’s competitive advantage lies in its specialized workforce, facilities, and long-standing relationships with the Navy, which create high barriers to entry.

HII’s primary customer is the U.S. Navy, which accounts for nearly all of its revenue. The company also serves the U.S. Coast Guard, other government agencies, and international allies through foreign military sales. Geographically, operations are concentrated in the United States, with shipyards in Virginia and Mississippi, and service facilities across the country. International sales are limited but growing through partnerships and direct sales of ships and services.
