Huntington Ingalls Industries builds ships and offers technology services, mostly for the U.S. government. It is based in Newport News, Virginia, and employs over 44,000 people. It says its two shipyards have built more ships in more ship classes than any other U.S. naval shipbuilder. Most of its business is with the U.S. government, mainly the Department of War.
It has three segments. Ingalls Shipbuilding, in Pascagoula, Mississippi, builds non-nuclear ships for the Navy and Coast Guard: amphibious assault ships, guided missile destroyers and Coast Guard cutters. It is the only builder of the Navy's amphibious assault ships and one of two builders of its destroyers. Newport News Shipbuilding, in Virginia, designs and builds nuclear ships, including aircraft carriers and submarines, and does refueling, overhaul and repair work. Mission Technologies sells communications, cyber, intelligence, unmanned systems, training and electronic warfare products and services.
In 2025 the company agreed with the Coast Guard to end production of the 11th and last national security cutter.
