Huntington Ingalls Industries (HII) is the largest military shipbuilding company in the United States and a cornerstone of American naval and maritime defense capability. The company designs, builds, overhauls, and maintains some of the most complex vessels in the world, including nuclear-powered aircraft carriers, submarines, amphibious assault ships, and advanced surface combatants that support U.S. Navy and Coast Guard operations.

For job seekers, HII offers careers across a uniquely broad mix of skilled trades, engineering, and mission support roles. Opportunities range from welders, pipefitters, electricians, and machinists in world-class shipyards to engineers working in naval architecture, software, cyber, AI, and systems integration. The company is especially attractive to veterans, apprentices, and cleared professionals who want hands-on work supporting national defense at massive industrial scale.

Unlike many defense companies focused primarily on software or systems integration, HII is deeply rooted in heavy industry and shipbuilding, combining traditional craftsmanship with modern defense technologies. Employees contribute directly to building and sustaining the U.S. Navy’s fleet, while increasingly working on advanced areas like unmanned systems, autonomy, and digital ship design as the company modernizes its production capabilities.

As global naval competition intensifies and the U.S. continues investing in fleet expansion, modernization, and maritime readiness, HII remains one of the most strategically important employers in the defense industrial base. For professionals seeking stable, long-term careers with tangible national impact—whether in the shipyard or in advanced engineering roles—Huntington Ingalls Industries stands out as a foundational pillar of American defense.
