Huntington Ingalls Industries is the largest independent military shipbuilder in the US, spun out of 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.
