Defense and Security Composite Products Serving California Customers

California is home to one of the largest concentrations of defense contractors, security integrators, and aerospace manufacturers in the United States. The composite components required for these applications have to perform under operational stress, conform to strict material and dimensional specifications, and arrive on schedule. We manufacture a wide range of defense composite structures for California-based customers and national defense accounts, working directly from customer drawings to deliver parts that are accurate, compliant, and integration-ready. Here is what we build:

• Radomes
• Antenna Covers
• Drone Boxes
• Ballistic Vehicle Panels
• RF-Transparent Defense Enclosures
• Tactical Composite Enclosures
• Lightweight Ballistic Composite Panels
• High-Performance Composite Structures
• Durable Fiberglass Defense Components
• Composite Structures for Military Applications

Standard and Custom-Engineered Defense Composite Products for California

California defense and security customers need composite products built to exact specifications, delivered on a reliable schedule, and supported through design changes without disrupting the program. We produce both standard composite structures and fully custom-engineered parts matched to the precise operational, dimensional, and material requirements of each project. Our production team works from customer drawings, builds tooling in-house, runs CNC machining and finishing on site, and ships parts ready for integration. Both single prototypes and high-volume production runs are within our scope.

Why California Defense and Security Manufacturers Trust Performance Composites

California defense and security manufacturers need a fabrication partner with the engineering capability and internal infrastructure to manage complex, evolving projects without disrupting delivery. We build our own tooling, run CNC machining in-house, handle all surface finishing on-site, and install hardware before anything ships. When a specification changes mid-production, our engineering team is steps from the shop floor and can respond the same day. California defense customers who choose us stay with us because the parts are right and the process is straightforward. Here is what that looks like:

  • More Than 40 Years of Manufacturing Experience
  • In-House Tooling Department
  • Internal Mold and Fixture Production
  • Integrated Engineering and Manufacturing Teams
  • Multiple Composite Manufacturing Processes
  • Precision CNC Machining Capabilities
  • Advanced Quality Inspection Systems
  • Cross-Industry Manufacturing Experience
  • Ready-to-Install Component Production
  • End-to-End Project Support

FAQs: Defense and Security Composite Manufacturing in California

We manufacture a broad range of defense and security composite structures for California customers, including radomes, antenna covers, drone boxes, ballistic vehicle panels, tactical enclosures, and RF-transparent housings. The majority of projects are custom-developed to meet specific performance, dimensional, and material requirements. We work from customer drawings and specifications and manage tooling, fabrication, machining, finishing, and hardware installation in-house.
Yes. RF-transparent composite fabrication is one of our established capabilities for California defense and security customers. We produce radomes, antenna covers, and related enclosures using materials and construction methods selected to meet specific radio frequency performance requirements. Wall thickness, reinforcement type, and resin system are all chosen based on the frequency range and signal performance criteria of the individual application.
Yes. Prototype development is a core part of what we do for California defense and security customers. Our team supports the full prototyping cycle, from design refinement and material selection through fabrication, dimensional inspection, and test preparation. Because tooling is built entirely in-house, the path from a design concept to a physical prototype is shorter and more responsive than working through outside toolmakers.
Yes. We manufacture composite structures for ballistic-performance applications, using materials and layup configurations tailored to the specific threat level and structural requirements of each project. Requirements vary significantly by application, and we work directly with California defense customers on those specifications during the engineering phase. Material selection and construction method are confirmed against the performance target before production begins.
Yes. Fire-retardant composite fabrication is a standard capability for California defense and security projects. We produce parts and panels to applicable fire retardance standards using resin systems and manufacturing processes selected to achieve the required rating. Fire retardance is treated as a design input from the start of the project rather than a specification retrofitted to an existing construction approach.
Our California defense and security projects draw on fiberglass, carbon fiber, and Kevlar reinforcements, paired with epoxy, vinyl ester, or polyester resin systems, depending on performance requirements. For sandwich panel construction, we select from foam, honeycomb, and G10 core materials based on structural load and weight targets. Every material decision is driven by the operational environment, performance specifications, and any applicable military or industry standards the project must satisfy.
Yes. Hardware installation before delivery is standard practice on California defense and security projects we fulfill. We source and install brackets, inserts, mounting hardware, and other assembly components at our facility so customers receive parts that go directly into their integration process. That reduces assembly time on the customer side and removes a handling step that can introduce damage or dimensional risk between fabrication and final use.
Defense and security specifications change, and our structure is designed for it. Engineering, tooling, manufacturing, and quality all operate under one roof, so when a change comes in, the people who need to act on it are already working together. Revisions move from engineering review to updated tooling to adjusted production faster than they would if those functions were split across separate shops or suppliers.
Our quality team uses 3D scanning and coordinate measuring machine technology for dimensional verification across California defense and security projects. Inspection plans and documentation packages are developed to match customer specifications and project requirements. All work is managed under our ISO 9001:2015 quality system, which maintains material traceability, process records, and inspection data from initial receiving through final shipment.
Yes. The majority of California defense orders leave our facility with machining, finishing, hardware installation, inspection, and packaging already completed. Customers receive parts that move directly into integration or assembly without additional processing. That level of delivery completeness is one of the main reasons California defense manufacturers bring repeat projects to our team.
Yes. We work with defense and security customers throughout California, from Southern California defense contractors and aerospace integrators to Northern California technology companies and security equipment manufacturers. Our facility is centrally positioned to serve the California defense corridor, and we regularly manage projects for customers at locations across the state. Remote project management is available for customers who prefer to work without on-site visits.
Yes. California defense and security customers are welcome to visit our production facility for engineering reviews, in-process inspections, and first article verification. Scheduling a visit is straightforward through our project management team, and we encourage California customers to stay closely involved at key milestones. On-site reviews help align expectations early and reduce the likelihood of revisions late in production.
Yes. We support California defense and security customers from the first prototype through sustained production volumes. Our in-house tooling team develops and builds molds quickly, which means there is no waiting on outside toolmakers between prototype approval and production start. Many California defense projects that begin with a single prototype develop into ongoing production relationships with our team as the customer scales their program.
