Huntington Ingalls Industries

What Huntington Ingalls Industries does

Huntington Ingalls Industries (NYSE: HII) is America's largest military shipbuilder, operating through three divisions: Ingalls Shipbuilding (Pascagoula, Mississippi) builds amphibious transport docks (LPD), large-deck amphibious assault ships (LHA), Arleigh Burke-class Flight III destroyers, and Coast Guard cutters; Newport News Shipbuilding (Newport News, Virginia) is the sole builder of Ford-class nuclear aircraft carriers and one of only two U.S. shipyards capable of building Virginia-class nuclear-powered submarines, in a teaming arrangement with General Dynamics Electric Boat; and Mission Technologies (headquartered in McLean, Virginia) delivers C5ISR, electronic warfare, cyber, directed energy, advanced materials, and autonomous maritime systems. The company traces its origins to 1886, was spun off from Northrop Grumman in 2011, and completed its IPO in 2012.

The product portfolio spans nuclear aircraft carriers and submarines, surface combatants, unmanned underwater vehicles (REMUS 130/300/620/6000 family with 750+ units delivered across 30 countries), unmanned surface vessels (ROMULUS family including ROMULUS-25 delivered to the U.S. Marine Corps), and a software stack centered on the Odyssey Autonomy Suite, Minotaur Mission Management System, and LeviathanAI agentic AI platform. Supporting products include Cognitive EW, VIPER/TIREM RF propagation modeling, CLOAK GPS anti-jam, GRSLi navigation warfare, GRIMM spectrum dominance, directed-energy weapons, and cyber/electronic warfare tools.

HII generates revenue primarily through multi-year U.S. Department of Defense contracts — both negotiated sole-source awards for nuclear programs and competitive procurements for surface combatants and amphibious ships — augmented by Foreign Military Sales to 14 allied NATO navies and other allied governments. FY2025 revenue was approximately $12.5 billion with an $54 billion backlog providing multi-year visibility. Pricing is contract-quoted rather than list-based, with shipbuilding acting as the long-duration revenue anchor and Mission Technologies supplying a higher-velocity mix of autonomy software, EW, and C5ISR solutions.

Direct peers

• General Dynamics: Operates Electric Boat, the only other U.S. shipyard building nuclear submarines and HII's Virginia-class teaming partner. Also a top-tier U.S. defense prime (Gulfstream, Bath Iron Works surface combatants), making it the closest direct comparable across HII's naval shipbuilding portfolio.
• BAE Systems: Major international shipbuilder and naval systems integrator with comparable combat systems, naval repair, and submarine/surface combat work. BAE Systems, Inc. (U.S.) operates Norfolk and San Diego shipyards handling destroyers, amphibs, and CVN overhauls that directly overlap with HII's services portfolio.
• L3Harris Technologies: Direct peer in defense electronics, C5ISR, and integrated mission systems for naval and joint customers. Comparable to HII Mission Technologies in unmanned systems integration, EW, and ISR payloads across DoD.
• Bath Iron Works (General Dynamics): GD-owned destroyer yard in Maine that is the principal U.S. peer to Ingalls Shipbuilding for Arleigh Burke-class DDG-51 construction, sharing Navy surface combatant workload.

Broad incumbents

• Northrop Grumman: Former parent of HII's shipbuilding operations (Northrop Grumman Ship Systems, 2001-2011). Today it is a broad incumbent across naval defense with Virginia-class submarine work at Newport News as a teaming partner, plus carriers (CVN-68 prime), B-21, and strategic systems directly adjacent to HII's portfolio.
• Lockheed Martin: U.S. defense prime serving as the Aegis Combat System integrator on HII-built destroyers and providing submarine combat systems (Virginia-class). Indirect adjacency via shared platforms and a similar B2G revenue model with concentrated DoD exposure.
• RTX (Raytheon): Major defense prime with adjacent C5ISR, EW, and undersea sensor portfolios (Raytheon Missiles & Defense, Collins Aerospace). Competes with HII Mission Technologies in EW and integrated mission systems for DoD customers.

Emerging players

• Anduril Industries: Fast-growing defense tech competitor in autonomous systems, undersea vehicles, and Lattice-style autonomy software. Directly comparable to HII's Odyssey/ROMULUS/LeviathanAI autonomy portfolio and the most credible emerging threat to HII Mission Technologies' growth trajectory.
• Shield AI: Autonomy and AI platform company that already partners with HII on ROMULUS. Its Hivemind autonomy stack and V-BAT UAS franchise make it both a partner and an emerging competitor in defense autonomy and unmanned systems.

Regional players

• Saab: European defense prime with submarine (A26), surface combatant, and unmanned underwater vehicle programs. Comparable to HII in naval shipbuilding but primarily serves non-U.S. NATO/allied navies, making it a regional rather than direct U.S. competitor.
