Huntington Ingalls Industries (HII) is the largest military shipbuilder in the United States and one of the biggest defense companies in the world. It builds aircraft carriers and submarines through Newport News Shipbuilding in Virginia, surface combatants and amphibious ships through Ingalls Shipbuilding in Mississippi, and runs a defense-tech and services arm called Mission Technologies. If you are trying to sell to HII, the first thing to understand is that it does not behave like a retailer or a Fortune 500 consumer brand with one tidy "become a supplier" button. It is a federal prime contractor, and that shapes everything about how you get in.
What Huntington Ingalls actually buysHII spends in the neighborhood of $1 billion a year with outside suppliers, and it states that nearly half of that goes to small businesses. That is a real number worth sitting with. It tells you two things: the spend is large, and small businesses are not an afterthought here. They are structurally part of how a federal shipbuilder meets its subcontracting obligations.
The buying breaks down across the divisions. Ingalls and Newport News need the things shipyards need: steel and metal fabrication, electrical and piping components, valves, machined parts, coatings, welding consumables, industrial supplies, calibration and testing, scaffolding, staffing, and a long tail of MRO (maintenance, repair, operations) goods. Mission Technologies buys differently because it is services and technology, things like engineering support, IT, cyber, training, and unmanned systems work. Match what you sell to the right division before you do anything else. A machine shop and an IT staffing firm do not knock on the same door.
How registration actually worksThere is no single "apply to HII" form that routes you everywhere. Registration runs through the divisions, and the cleanest documented path is Ingalls Shipbuilding.
For Ingalls, the entry point is the Socio Economic Business Program (SEBP), which functions as the small business liaison office. HII's own guidance is direct: any supplier interested in doing business with Ingalls should contact the SEBP first. The next concrete step is completing a Supplier Information profile, the company profile form on the Ingalls Material Acquisition forms site. That profile is how Ingalls qualifies you. It is not a contract, and it is not a guarantee anyone calls. It is the record that puts you in the system so a buyer can find you when a need comes up.
This is the part founders get wrong. Filling out the profile is necessary, but it is passive. HII, like most defense primes, is invitation-leaning. Buyers pull from qualified suppliers when a requirement exists, often tied to a specific Navy program and its flow-down requirements. You will not bid on much by sitting in a database and waiting. The profile gets you eligible. Relationships and program timing get you invited.
One more reality check on the procurement system itself: HII does not publicly advertise a brand-name platform like SAP Ariba or Coupa for general supplier onboarding. Ingalls uses its own web-based supplier information form and supplier portals. Treat the division small business office, not a third-party portal, as your real point of contact.
How to get noticed and invitedRegistering is table stakes. Getting invited is the actual work.
- Talk to the small business office before you sell. The SEBP exists to connect prospective suppliers to opportunities. Reach out, describe specifically what you make or do, and ask what they are sourcing. A short, concrete capability summary beats a generic brochure.
- Get your federal house in order. Active SAM.gov registration, a CAGE code, the right NAICS codes, and any quality certifications relevant to shipbuilding (think AS9100, ISO 9001, NADCAP where it applies) make you a serious candidate rather than a maybe.
- Understand the flow-downs. Because HII is a defense prime working Navy contracts, its subcontracts carry federal clauses, cybersecurity requirements (CMMC is becoming real for the defense supply chain), and sometimes ITAR considerations. Show up already understanding that you will inherit those obligations.
- Be findable. A clean, specific capability statement and public supplier profile help a buyer confirm in thirty seconds that you fit. Vague positioning gets skipped.
Here is where certification earns its keep. HII runs a Supplier Diversity Program and is explicit about wanting partnerships with small and disadvantaged businesses. As a defense prime, HII has federal small business subcontracting goals to hit, covering categories like small disadvantaged business, women-owned small business (WOSB), service-disabled veteran-owned small business (SDVOSB), HUBZone, and 8(a). Your certification is not a nice-to-have on that scorecard. It is the thing that lets a buyer count your award toward a goal they are measured on.
The certifications that move the conversation with a federal shipbuilder are mostly the federal ones: SBA's 8(a), HUBZone, WOSB/EDWOSB, and SDVOSB/VOSB through the VA's VetCert. Corporate certifications like NMSDC's MBE and WBENC's WBE still carry weight, especially for the diversity-spend reporting side, and they signal credibility broadly. If you are minority-owned and have not yet certified, the NMSDC MBE certification is the recognized standard on the corporate side. If managing several certifications across federal and corporate programs sounds like a full-time job, CertifyAll was built to capture your business information once and handle the applications for you.
Before you lean hard on any single certification with HII specifically, confirm which ones the relevant division names in its current sourcing. The strongest position is holding the federal certification that matches the subcontracting category a buyer is trying to fill.
The Tier-2 side doorThere is a second route that founders overlook. HII is a prime, which means most of the dollars it manages flow into large subcontracts with other big firms. Those firms also carry small business subcontracting plans. If you cannot win directly with HII yet, you may be able to subcontract to one of HII's larger suppliers and still be working on the same hull.
HII does not publicly publish a packaged "Tier-2" program the way some corporate buyers do, so treat second-tier as a strategy rather than a named portal. Ask the small business office which primes hold large packages in your category, then approach those firms with your certifications in hand. It is often a faster first contract than a direct award, and it gets your name onto an HII program before you ever sell to HII directly.
Where to startIf you build or supply something a shipyard needs, start with Ingalls' small business office and complete the supplier information profile. Get your SAM registration and federal certifications current. Then work the relationships, because the database is the floor, not the path.
