San Bernardino sits at the center of one of California’s most active defense supply chains. Norton Air Force Base may have closed, but its legacy lives on — the Inland Empire is now home to major defense MRO operations, logistics support contractors, and Tier 2 suppliers feeding programs at March Air Reserve Base and across Southern California’s defense corridor. Nimble connects local defense primes and subcontractors to a certified partner network capable of producing MIL-SPEC sheet metal components with full traceability, ITAR compliance, and first article inspection on every order. If you’re sourcing enclosures, chassis, brackets, or structural weldments for defense applications, this is built for you.
The Inland Empire region supports a dense network of defense contractors and MRO providers tied to March ARB, Edwards AFB, and the broader Southern California aerospace corridor. Companies like Stater Bros. Logistics, Amazon Defense Logistics, and numerous Tier 2 defense suppliers operate distribution and fabrication support out of the San Bernardino metro. With the National Orange Show Events Center repurposed for industrial use and ongoing SBDO-backed manufacturing incentives, the city is actively rebuilding its industrial base around defense, logistics, and heavy fabrication.

// FAQ
Common questions about Sheet Metal Fabrication for Defense & Military in San Bernardino, CA.
Is your partner network ITAR-registered for defense work originating in San Bernardino?
Yes. All partner shops handling defense-related sheet metal fabrication through Nimble are ITAR-registered. Technical data, drawings, and component details are handled in compliance with EAR and ITAR requirements. We do not route defense work through non-registered facilities.
Can you produce sheet metal parts to MIL-SPEC standards for Inland Empire defense contractors?
Absolutely. Our certified partner network fabricates to MIL-SPEC tolerances and finishes — including MIL-DTL-5541 chemical film (Alodine), MIL-A-8625 anodize, and MIL-PRF-23122 primer systems. Material certifications and full traceability documentation are included with every defense order.
How quickly can Nimble turn around a quote for a defense sheet metal assembly needed near March ARB?
Standard quote turnaround is 24 hours from receipt of drawings or CAD files. For urgent defense procurement requirements tied to March Air Reserve Base programs or Inland Empire MRO ops, contact us directly at +1 (872) 347-2224 and we’ll prioritize your RFQ.
Do you support First Article Inspection (FAI) requirements for defense prime contractors in San Bernardino County?
Yes. CMM inspection and FAI are included on every order — no upcharge, no negotiation. If your prime contractor or DCMA representative requires AS9102 FAI documentation, we coordinate that through our AS9100-certified partner network and deliver it with your first shipment.
What sheet metal materials and thicknesses does your network work with for military applications?
Our partner network processes aluminum (5052, 6061, 7075), stainless steel (304, 316, 17-4 PH), mild steel (A36, A572), and titanium sheet — from 24 gauge through 0.5″ plate depending on process. All materials are sourced with mill certs. If your program calls for a specific AMS or ASTM spec, tell us on the RFQ and we’ll confirm availability upfront.
