DoD primes are held to negotiated small business, small disadvantaged business, HUBZone, SDVOSB, and WOSB subcontracting goals under FAR 52.219-9. Many DoD subcontracts also carry CMMC and cybersecurity flow-down expectations, so sourcing subs that can meet those requirements matters as much as certification status. This includes Army, Navy, Air Force, DLA, and defense agencies.
Find DoD small business subcontractors
The Department of Defense is the largest buyer in the federal government, and most large DoD prime contracts carry a small business subcontracting plan. Primes on Army, Navy, Air Force, and defense-agency work use SamMatch to find qualified small business subcontractors by NAICS, certification, and capability.

Frequently asked questions
Does SamMatch have DoD-specific subcontractor data?
SamMatch matches from the SAM.gov / SBA Small Business Search (SBS) small business pool by NAICS, certification, and capability. It does not maintain agency-specific award graphs — you bring the requirement, and SamMatch ranks qualified subs for it.
Can SamMatch screen subs for CMMC flow-down?
SamMatch supports CMMC self-attestation filters to help DoD primes shortlist subs. Self-attestation is not certification — always verify cyber requirements directly with the subcontractor.
