San Diego is the largest defense market in California. Defense contracts in the region ran to roughly $19.8 billion across more than 2,000 companies in the most recent reporting year, and military spending accounts for about 22% of the regional economy. GERC registers San Diego suppliers, secures certification, prepares CMMC compliance and writes the bids.
A Navy and maritime market, not an aerospace one
San Diego buys differently from Los Angeles. The demand here is shaped by the fleet and its shore establishment: ship repair and modernisation, maritime systems, unmanned surface and undersea vehicles, C4ISR and naval information warfare, base operations, facilities and logistics. Suppliers who understand that mix compete very differently from a firm chasing space and missile work up the coast.
Scale cuts both ways. More than 2,000 companies already hold defense contracts here, so the market is genuinely competitive and the incumbents are well established. The most recent report also showed a 3% decline from the prior year on federal budget pressure. That makes certification and cyber compliance more decisive rather than less, because they are increasingly what separates two otherwise similar bidders.
Where a small San Diego firm can realistically compete
- Ship repair and industrial trades. Welding, machining, coatings, electrical and habitability work through the repair primes.
- Unmanned systems and maritime technology. A fast-growing segment where SBIR and STTR routes are genuinely open to small companies.
- Facilities, base operations and environmental services. Recurring requirements with small business set-asides.
- Professional, engineering and technical services. Where set-asides and socio-economic certifications carry the most weight.
- Supply, logistics and distribution. Through DLA DIBBS as well as regional solicitations.
What we handle for San Diego contractors
- SAM.gov registration, UEI and entity validation, and CAGE code.
- DLA DIBBS registration and JCP certification for firms supplying parts and components.
- 8(a), HUBZone, DVBE and SDVOSB certification, which matter disproportionately in a set-aside heavy market.
- NIST SP 800-171 and CMMC readiness, including System Security Plan, POA&M and SPRS submission.
- Capability statements, proposals and SBIR or STTR applications written against the evaluation criteria.
How we work with defense suppliers
- Readiness review. Whether your registrations, certifications and cyber posture actually let you bid what you want to bid.
- Registration. SAM.gov, UEI and entity validation, CAGE code, and DLA DIBBS with JCP where you need controlled drawings.
- Certification. SB, SB-PW, DVBE, 8(a) and HUBZone where you qualify, plus California SB for state work alongside federal.
- Cyber compliance. NIST SP 800-171 gap assessment, System Security Plan, POA&M and SPRS score submission ahead of CMMC assessment.
- Bidding. Capability statement written for defense buyers, then proposals and SBIR or STTR applications.
Common questions
Is San Diego too competitive for a new contractor?
It is competitive, with over 2,000 companies already holding defense contracts. That makes preparation decisive. Set-aside eligibility and a current SPRS score are frequently what separates bidders, and many established firms have let one or the other slip.
Which certifications matter most in San Diego?
Set-aside driven ones: 8(a), HUBZone, SDVOSB and DVBE. The services and base operations work that dominates this market carries small business set-asides more often than large system contracts do.
Do I need CMMC for Navy work?
If your contract involves Federal Contract Information or Controlled Unclassified Information, yes, and it reaches subcontractors through prime flow-down. Ship repair and technical services work commonly falls in scope.
Can a San Diego company bid on both federal and California state contracts?
Yes, and they are separate systems. Federal work runs through SAM.gov, state work through Cal eProcure with its own Small Business certification and 5% bid preference. Firms selling to both need both.
What is the fastest route in for a small firm?
Usually subcontracting to an established prime while your own registrations and cyber compliance mature, then bidding set-asides directly once you can evidence past performance.
