Northrop Grumman spends billions a year with outside suppliers, and almost none of it starts with a cold bid. There's no public RFP board you can browse and respond to. The company runs a gated intake process, and if you don't go through it the right way, your capabilities never reach a buyer.
So the question "how do I become a Northrop Grumman supplier" has a specific answer, and it's not "wait for an opportunity to post." It's "get into their system, get invited to register, and make sure the right small business contact knows you exist." Here's how that actually works.
Start with the Supplier Information FormEvery prospective supplier begins at the same door: the Supplier Information Form, hosted on Northrop Grumman's intake portal at oasis-sbeforms.myngc.com. This is the express-interest step. You tell the company who you are, what you make or do, and which capabilities you bring.
Submitting the form does not make you a supplier. It routes your information to the correct business unit so the right buyers and small business team can see it. If there's interest, Northrop Grumman contacts you to move forward. If there isn't a current need that fits, you may not hear back right away, which is normal for a prime this size.
Treat this form like a pitch, not a registration. Be precise about your NAICS-aligned capabilities, your certifications, your facility clearances if you hold them, and any past performance with defense or aerospace primes. Vague answers get filed and forgotten.
The Ariba step: registration only happens by invitationNorthrop Grumman manages supplier registration through the SAP Ariba Network. Here's the part that confuses people: creating an Ariba Network account does not register you as a Northrop Grumman supplier.
The sequence is:
- You submit the Supplier Information Form. This is your introduction.
- Northrop Grumman invites you to connect on the Ariba Network, if there's a fit.
- You create or log into your SAP Ariba account and accept the connection.
- You complete Northrop Grumman's Registration Questionnaire inside Ariba.
- Northrop Grumman reviews and approves the questionnaire. Only then are you a registered supplier.
You can't skip to step three. The invitation gates everything. Plenty of vendors set up an Ariba account, assume they're in the pipeline, and never understand why nothing happens. The questionnaire approval is the line that matters.
Once you're registered, you get access to OASIS, Northrop Grumman's Online Automated Supplier Information System, which is the suite of tools suppliers use day to day for things like invoice and payment inquiries. OASIS is the working environment after you're in, not a way in.
Where small and diverse businesses get noticedThe intake form is the front door, but for a small or diverse firm, the form alone is rarely enough. The faster path runs through Northrop Grumman's Office of Small Business Programs (OSBP).
OSBP is the in-house team that advocates for small business participation across Northrop Grumman's programs and supply chain. Its stated objective is to maximize opportunities for small businesses to contribute across the company's work. The office serves the federal small business categories you'd expect a defense prime to track: small disadvantaged businesses, women-owned small businesses, veteran-owned and service-disabled veteran-owned small businesses, HUBZone firms, and HBCU/minority institutions.
A note on naming. Northrop Grumman previously promoted a "Global Supplier Diversity Program." Following the federal executive orders on diversity programs in early 2025, the company issued a January 24, 2025 statement saying it was reviewing its policies for compliance, and the public-facing supplier engagement is now framed around the Office of Small Business Programs and federal small business contracting categories rather than a standalone diversity brand. The underlying mechanism, getting capable small and diverse firms into the supply chain, is still there. The label and the framing have shifted. If you're certified as an MBE, WBE, VBE, or through a similar third-party body, that status still helps you qualify under the federal categories Northrop Grumman reports against; just don't assume a specific corporate certification mandate the company hasn't published.
The practical move: OSBP publishes division-specific small business contacts. Northrop Grumman is organized into divisions including Aeronautics Systems, Defense Systems, Mission Systems, and Space Systems, plus the corporate office, and each has its own small business email address. Identify which division buys what you sell, then send a tight capability statement to that division's contact. Northrop Grumman also points potential suppliers, small or large, to its Small Business Liaison Officers (SBLOs) as an initial point of contact. Use them.
The development programs worth knowingTwo OSBP programs are worth understanding because they're how a small firm goes from "registered" to "growing inside the supply chain."
Mentor-Protégé Program. Defense primes run formal mentor-protégé relationships, often tied to DoD's program, where the prime provides technical and business development assistance to a smaller protégé firm. This is a real growth lane, not a logo exercise. It usually comes after you've established yourself as a capable supplier, not on day one.
SBIR/STTR support. If you're a technology or R&D firm, Northrop Grumman engages with the Small Business Innovation Research and Small Business Technology Transfer programs, the federal mechanisms that fund early-stage research with small businesses. For the right company, this is a way to get on a prime's radar through innovation rather than through commodity supply.
Tier 2 and the subcontracting mathHere's the angle most small suppliers miss. As a federal prime, Northrop Grumman carries small business subcontracting goals on its major contracts. When the company wins a large federal program, it commits to flowing a percentage of that work down to small and small disadvantaged businesses. That commitment is reported and tracked.
That means your certifications aren't just a label, they're a line item the prime needs to hit. A small disadvantaged or women-owned or veteran-owned firm that's registered, responsive, and easy to work with helps Northrop Grumman meet a contractual obligation. Frame your outreach that way. You're not asking for a favor; you're solving a reporting problem for them.
This is also why getting your certifications in order before you reach out pays off. If you're weighing which certifications actually open doors at primes like Northrop Grumman, Lockheed, and RTX, CertifyAll handles the filing across the relevant federal and third-party programs in one pass, so you show up with the credentials a prime's small business team can count.
A realistic on-rampSet expectations. Becoming a Northrop Grumman supplier is a months-long relationship build, not a transaction. A realistic sequence looks like this:
- Get your foundation set. Active SAM.gov registration, the right NAICS codes, a clean capability statement, and any certifications that map to the small business categories Northrop Grumman reports against.
- Submit the Supplier Information Form at the intake portal with specific, defense-relevant capabilities.
- Reach out to the OSBP division contact that matches your offering. Don't wait on the form alone.
- If invited, complete Ariba registration and get the Registration Questionnaire approved.
- Deliver as a subcontractor or lower-tier supplier first. Past performance with the prime is what unlocks bigger work and programs like mentor-protégé.
Most diverse suppliers who break into a prime don't start with a marquee contract. They start with a small, well-executed order, build a track record, and grow from there.
Don't stop at one primeNorthrop Grumman is one of several aerospace and defense primes running near-identical intake and small business processes. The work you do to register with one, your capability statement, your certifications, your NAICS alignment, transfers directly to Lockheed Martin, RTX, General Dynamics, Boeing, and L3Harris. Build the package once, then submit it across all of them.

Registration gets you into Northrop Grumman's system. What gets you contracts is showing up as a credentialed, specific, reliable supplier the small business team can plug into a goal they already have to meet.
