Huntington Ingalls Industries

Huntington Ingalls Industries operates three businesses built around the U.S. Navy's hardest-to-replace industrial capabilities. Newport News Shipbuilding designs, builds, refuels, overhauls and inactivates nuclear-powered aircraft carriers and shares nuclear-submarine construction with General Dynamics Electric Boat. Ingalls Shipbuilding builds surface combatants and amphibious warships. Mission Technologies adds unmanned maritime systems, command-and-control, cyber, electronic warfare, artificial intelligence, training and other mission services.

The shipbuilding businesses are strategically protected but operationally unforgiving. Newport News is the only U.S. yard that can build, refuel and inactivate nuclear-powered aircraft carriers and one of only two U.S. yards capable of building nuclear-powered submarines. Ingalls is one of two builders of Arleigh Burke-class destroyers and the sole builder of the Navy's large-deck amphibious assault ships.

Customer concentration is extreme by normal commercial standards and normal by naval-prime standards. In 2025, $12.470 billion of HII's $12.484 billion of revenue came from the federal government. The U.S. Navy alone accounted for about 81% of revenue. That produces unusually strong demand visibility but makes appropriations, Navy priorities, contract estimates and ship-delivery performance central to the business.

Ingalls Shipbuilding

Ingalls in Pascagoula, Mississippi builds Arleigh Burke-class Flight III guided-missile destroyers, America-class large-deck amphibious assault ships and San Antonio-class amphibious transport docks. It also provides planning-yard and fleet-support work. In April 2026 the Navy awarded Ingalls the FF(X) frigate lead-yard support contract, giving the yard responsibility for long-lead material, design work and pre-construction activity for the first ship. Q2 2026 revenue was $845 million, up 16.7% year over year, with a 6.9% segment operating margin.

Newport News Shipbuilding

Newport News is HII's nuclear-maritime franchise. It is the sole U.S. designer, builder and refueler of nuclear-powered aircraft carriers and works on Ford-class construction, Nimitz-class refueling and complex overhauls, fleet support and carrier inactivation. On Virginia-class attack submarines it shares construction with General Dynamics Electric Boat. On Columbia-class ballistic-missile submarines, Electric Boat is prime while Newport News builds and delivers six major module sections per boat. Q2 2026 revenue was $1.849 billion, up 15.3%, with a 6.0% segment operating margin.

Mission Technologies

Mission Technologies broadens HII beyond shipyards. Its portfolio includes REMUS unmanned underwater vehicles, ROMULUS unmanned surface vessels, Odyssey autonomy software, C5ISR, artificial intelligence and machine learning, electronic warfare, cyber, synthetic training, nuclear and environmental services and readiness support. Q2 2026 revenue was $760 million, down 3.9% year over year, while segment operating margin improved to 7.2% and EBITDA margin reached 10.1%. The Navy selected ROMULUS for the Medium Unmanned Surface Vessel evaluation phase, HII delivered the first REMUS 130 in June and by late August said ROMULUS 151 vessels were in serial construction at multiple Gulf Coast yards. Mission Technologies also received the STINGRAI task order for U.S. Southern Command, a seven-year vehicle with a disclosed total ceiling of about $2.18 billion.

HII's near-term growth is being driven by volume, not a new commercial market. Q2 2026 revenue increased 10.9% to $3.418 billion as higher aircraft-carrier and submarine work lifted Newport News and higher amphibious volume lifted Ingalls. For the first half, revenue increased 12.1% to $6.517 billion. Management raised full-year shipbuilding revenue guidance to $10.2 billion-$10.4 billion and lifted the low end of shipbuilding margin guidance to 6.0%-6.5%.

The constraint is the industrial system around those programs. HII increased shipbuilding throughput 14% in 2025 and is targeting another roughly 15% improvement in 2026. The company plans to outsource more than 2.5 million shipbuilding hours in 2026, 30% more than in 2025. A typical Arleigh Burke destroyer has about 77 structural units; HII says it now plans for 37 units to be produced by distributed partners, up from historically fewer than five.

That distributed model is spreading beyond destroyers. Ingalls has assigned eight structural units for Philadelphia (LPD 32) to outside partners. Newport News Charleston Operations is producing carrier and submarine work and HII said in July that production at the site had increased by more than 50% under HII ownership. On 06-AUG-2026, HII also announced performance-based production agreements under which it intends to award up to $900 million of shipbuilding work over seven years to Path Robotics and GrayMatter Robotics if technology, manufacturing-readiness, cost, schedule and quality milestones are met.

Mission Technologies is the other growth lane, but Q2 illustrated why it should be judged separately from shipbuilding. Revenue fell 3.9% to $760 million while operating margin rose to 7.2%, helped by higher equity income from nuclear and environmental joint ventures. HII still guides Mission Technologies to $3.0 billion-$3.2 billion of FY2026 revenue, about a 5% segment operating margin and an 8.4%-8.6% EBITDA margin.

The 29-JUL-2026 submarine package materially extends demand visibility, but it does not create a clean new $76.6 billion HII revenue opportunity. The package is shared with General Dynamics Electric Boat and HII has not publicly disclosed its individual share. What it does show is that the Navy is committing to the next production blocks while the industrial base is still trying to recover schedule and throughput.

Management is attacking that bottleneck from several directions at once: Charleston Operations, more distributed structural work, partner-built grand blocks, automation with HD Hyundai Heavy Industries and up to $900 million of milestone-based production work with Path Robotics and GrayMatter Robotics. The model is straightforward: move repeatable fabrication away from the two core yards so scarce in-yard labor and facilities can concentrate on nuclear, integration and final-assembly work that cannot be shifted elsewhere.

The financial test arrives in the second half. HII used $421 million of operating cash and generated negative $611 million of free cash flow in the first six months, yet still guides to positive $500 million-$600 million of FY2026 free cash flow. That requires a sharp working-capital and milestone-payment reversal. The Q2 balance sheet showed only $12 million of cash, though management reported $1.7 billion of liquidity.

Over the medium term, HII is targeting roughly 6% top-line compound annual growth and more than $16 billion of enterprise revenue by 2030. Management also expects margin expansion as challenged pre-COVID ship contracts burn down and newer awards with better-balanced risk enter the mix. Those targets are plausible only if schedule performance improves fast enough to keep contract-estimate adjustments from consuming the benefit of higher volume.

The deepest moat is nuclear shipbuilding scarcity. Newport News is the only U.S. shipyard capable of designing, building and refueling nuclear-powered aircraft carriers and one of only two yards capable of designing and building nuclear-powered submarines. Those capabilities require nuclear-qualified facilities, specialized suppliers, security infrastructure and a workforce whose experience compounds over decades. A new competitor cannot reproduce that system on a normal commercial timetable.

Ingalls has a different but still substantial barrier. It is one of two Arleigh Burke destroyer builders and the sole builder of the Navy's large-deck amphibious assault ships. The yard's production lines, Navy qualification history and integration experience create switching costs even when the underlying hull is not nuclear.

Distributed shipbuilding is an attempt to extend that moat without trapping every fabrication hour inside the scarce core yards. Charleston Operations, Gulf Coast partners, HD Hyundai Heavy Industries and the HYPR robotics agreements can increase effective capacity if the outside work arrives on time, at quality and sufficiently outfitted for final integration. That is more valuable than adding factory square footage alone.

Mission Technologies has a weaker structural moat because its markets are more competitive. Its advantage comes from combining a large installed maritime-autonomy base, cleared engineering, Navy customer access and ship-platform knowledge with REMUS, ROMULUS and Odyssey. That can improve win probability in maritime missions, but it does not eliminate recompetes or task-order competition.

The moat protects demand more reliably than margin. HII is difficult for the Navy to replace. The Navy is also difficult for HII to replace. That bilateral dependence makes performance failures strategically important and financially expensive rather than commercially fatal in the normal sense.

Shipbuilding execution and contract estimates. HII recognizes much of its shipbuilding revenue over time using cost and progress estimates. In Q2 2026, net cumulative catch-up adjustments added $10 million to operating income, but that net figure masked a favorable $28 million adjustment on the USS John C. Stennis (CVN 74) refueling and complex overhaul and an unfavorable $48 million adjustment on the USS George Washington (CVN 73) overhaul. Higher volume does not help if schedule or cost estimates deteriorate faster.

Workforce and supplier throughput. HII employed more than 44,000 people at year-end 2025 and now describes its workforce as approximately 45,000, including about 7,000 engineers and designers. Roughly 45% of the workforce was covered by 13 collective-bargaining agreements. The company is expanding apprenticeships, outside fabrication and automation because ship demand already exceeds the comfortable capacity of the existing labor and supplier base.

Customer concentration. Nearly all 2025 revenue came from the federal government and the U.S. Navy represented about 81% of revenue. A defense-budget delay, continuing resolution, shutdown, program reprioritization or Navy schedule decision can affect several HII businesses at once.

Contract-type exposure. Approximately 46% of 2025 revenue came from fixed-price incentive contracts, 50% from cost-type contracts, 3% from firm-fixed-price contracts and 1% from time-and-material arrangements. Fixed-price incentive work can preserve upside when execution improves but shifts more cost risk to HII when estimates worsen.

Backlog timing and quality. Total Q2 backlog was $57.322 billion, including $34.594 billion funded and $22.728 billion unfunded. Those balances can change with appropriations and contract actions. The July submarine package is also shared with General Dynamics Electric Boat, so the headline combined value cannot be treated as HII backlog.

Cash conversion. HII generated negative $611 million of free cash flow in the first half but still guides to positive $500 million-$600 million for the year. That creates a large second-half conversion requirement tied to working capital, milestone payments and execution. Quarter-end cash was $12 million, partly offset by $1.7 billion of reported liquidity.

Mission Technologies recompete and volume risk. Q2 Mission Technologies revenue fell 3.9% even as profitability improved. IDIQ ceilings, evaluation-phase wins and technology demonstrations are not equivalent to funded task orders or recurring product volume.

Government, nuclear, cyber and environmental oversight. Nuclear work, classified programs, cost accounting, export controls, cybersecurity rules, labor standards and environmental obligations expose HII to audits, remediation costs and potential restrictions on contract performance.

Capital intensity and distributed-production integration. Moving more work to outside facilities expands effective capacity but adds supplier qualification, transport, interface and quality-control risk. Automation projects also require capital and engineering effort before they produce reliable savings.

HII became an independent public company on 31-MAR-2011 when Northrop Grumman spun off its shipbuilding assets. The corporate history is short. The industrial lineage is not. Newport News Shipbuilding was founded in 1886 by Collis P. Huntington and Ingalls Shipbuilding was founded in 1938 by Robert Ingersoll Ingalls Sr. Those yards built the physical base HII still depends on today.

The company's technology expansion accelerated after it established a third division in 2016. HII acquired marine-robotics company Hydroid in 2020 in a $350 million transaction, adding the REMUS family and a larger autonomous-maritime footprint. In 2021 it acquired Alion Science and Technology for $1.65 billion, adding cleared engineering, intelligence, surveillance and reconnaissance, cyber, data analytics, training and simulation capabilities that became core parts of Mission Technologies.

The more recent strategic move has been capacity rather than diversification. In January 2025 HII acquired substantially all assets of W International and Vivid Empire in South Carolina for $132 million. The operation became Newport News Shipbuilding Charleston Operations, adding a 45-acre site with more than 480,000 square feet of covered manufacturing space, barge and rail access and an existing workforce that can fabricate submarine modules and carrier units away from the main Newport News yard.
