Huntington Ingalls Industries is the largest independent military shipbuilder in the US, spun out from Northrop Grumman in 2011. It operates three segments, two of which are storied shipyards: Ingalls produces non-nuclear-powered ships, including amphibious landing ships and Arleigh Burke-class destroyers, while Newport News produces nuclear-powered ships as the only producer of Gerald Ford-class aircraft carriers and a major subcontractor on Virginia- and Columbia-class nuclear submarines. HII shares production of destroyers and nuclear submarines with General Dynamics' Bath Iron Works and Electric Boat shipyards, respectively.
