Wanted: Small Defense Contractors

Start by registering on SAM.gov (the System for Award Management — the federal vendor database, free to register). Then build a capability statement — a one to two page document explaining exactly what your company does, your NAICS codes (industry classification numbers), and any relevant certifications. Large prime contractors that hold DoD contracts over $750,000 are legally required to have subcontracting plans and actively seek small business subs. The SBA (Small Business Administration) runs SUB-Net — a database where primes post subcontracting opportunities. Direct outreach to small business liaison officers at prime contractors also works well.

SBIR stands for Small Business Innovation Research. It's a federal grant program specifically for small businesses developing new technology. DoD is the largest SBIR funder — it awards about $1.5 billion annually across all military branches. Phase I is the entry point: typically $50,000 to $256,000 for a 6 to 12 month feasibility study. Phase II continues the work: typically $750,000 to $1.5 million. Phase III is commercialization — where the technology transitions to a real DoD program. You apply through the SBIR.gov portal during specific open solicitation windows.

The most common NAICS codes (6-digit industry classification numbers) in defense contracting are: 54 (Professional, Scientific, and Technical Services — covers engineering, IT, consulting), 33 (Manufacturing — weapons systems, electronics, vehicles), 48 (Transportation and Warehousing), 23 (Construction — military facilities), and 81 (Other Services — maintenance and repair). Knowing your primary NAICS code determines which solicitations you can bid on and which set-aside categories you may qualify for.

IDIQ stands for Indefinite Delivery, Indefinite Quantity — a master contract that lets agencies place orders over time without running a new full competition each time. GWACs (Government-Wide Acquisition Contracts) are IDIQs available to multiple agencies. The most important for small defense contractors are OASIS (for professional services), Alliant (for IT), and the 8(a) STARS program (for small disadvantaged businesses). Getting on a GWAC requires competing in an on-ramp solicitation — but once you're on, you can bid on task orders for the life of the vehicle, often 5 to 10 years.

Three approaches work. First, the SBA's SUB-Net database lists active subcontracting opportunities posted by prime contractors. Second, prime contractors that receive large DoD awards publish small business subcontracting plans — these name the types of small businesses they're targeting. Third, PTAC (Procurement Technical Assistance Centers — free government contracting counselors) can help match your capabilities to active prime contractor needs. Our A1 report identifies the top prime contractors winning work in your technology area right now, which tells you exactly who to approach.
