Huntington Ingalls Industries, Inc. HII

HII Company Overview

Huntington Ingalls Industries, Inc. (HII) is a U.S.-based defense contractor and the largest military shipbuilder in the United States by revenue and tonnage delivered. The company designs, builds, overhauls, and maintains nuclear and non-nuclear naval vessels primarily for the U.S. Department of Defense, especially the U.S. Navy and U.S. Coast Guard. HII operates within the defense, aerospace, shipbuilding, nuclear engineering, and mission technologies industries. Its primary revenue drivers include aircraft carriers, nuclear-powered submarines, amphibious assault ships, surface combatants, fleet sustainment services, and defense-related technical and mission support services.

The company traces its roots to Newport News Shipbuilding, founded in 1886, and Ingalls Shipbuilding, established in 1938. HII was formed in 2011 when Northrop Grumman separated its shipbuilding businesses into an independent publicly traded company. Since then, HII has expanded beyond shipbuilding through investments in defense technologies, autonomous systems, cyber operations, artificial intelligence, and mission support capabilities. The company’s strategic positioning is reinforced by its status as one of only two U.S. shipyards capable of building nuclear-powered aircraft carriers and one of two capable of constructing nuclear-powered submarines for the U.S. Navy.
