Can HII Benefit From Growing Demand for Submarine Construction?

Huntington Ingalls Industries (HII) is positioning its Newport News Shipbuilding division to benefit from sustained U.S. submarine demand as the Navy expands and modernizes its undersea fleet. In July 2026, HII and General Dynamics Electric Boat received contract modifications totaling about $76.6 billion to support construction of five additional Columbia-class and nine additional Virginia-class submarines, plus investments in shipyard infrastructure. For the Virginia-class work, Newport News Shipbuilding will serve as the delivery yard for six submarines; for the Columbia-class program, it will build and deliver six major module sections per submarine. The article highlights HII’s experience as one of two U.S. shipyards capable of building nuclear-powered submarines, alongside ongoing investments to raise production volume.
