FDH DEFENSE AFTERMARKET, LLC

FDH DEFENSE AFTERMARKET, LLC specializes in the manufacturing and supply of mission-critical aerospace and defense components, with deep expertise in precision hardware, electronic subsystems, and aircraft ancillary equipment. The company produces bolted assemblies, electrical connectors, capacitors, relays, sealing devices, and oxygen delivery systems used in military and Coast Guard aviation platforms. Their technical proficiency spans metal forging, spring manufacturing, and the production of high-reliability passive electronic components, supporting the maintenance and sustainment of legacy and modern aircraft systems. Key differentiators include direct manufacturing control over complex fastening systems and electro-mechanical interfaces critical to flight safety and mission readiness. The contractor maintains a strong, consistent relationship with the Department of Defense, delivering components for aircraft systems including clutch assemblies, oil reservoirs, and auxiliary equipment. They also serve the Department of Homeland Security, particularly the U.S. Coast Guard, providing specialized parts such as oxygen masks and voice data recorder repair solutions for HC-130J platforms. Their work is narrowly focused on sustaining operational readiness through direct supply of certified, replaceable hardware rather than system integration or software development. Industry focus centers on NAICS 332722, 332510, and 336413—encompassing hardware, aircraft parts, and electronic component manufacturing. The firm operates as a niche Tier 2 supplier within the defense aerospace supply chain, specializing in high-volume, low- to mid-complexity parts requiring strict dimensional tolerances and material traceability. Their market positioning is that of a reliable, production-capable manufacturer for sustainment and repair markets, not primary system integrators. As a 2L entity based in Commerce, California, FDH DEFENSE AFTERMARKET, LLC is a small-scale manufacturer with no public certifications on record. Their geographic proximity to defense aerospace hubs supports rapid logistics and responsive fulfillment for time-sensitive government requirements.
