About the company
Johansing Iron Works, Inc., a California-based manufacturer of custom fabricated metal equipment and heat exchangers, operates as a subcontractor on naval and defense programs, with 60% of its recent award footprint rooted in subcontract work to prime integrators. The firm is a child entity of Unico Mechanical Corp., a for-profit organization based in Benicia, California.
Johansing Iron Works' award footprint is sparse but concentrated in naval and maritime systems. Over the past eight years, the vendor has received five federal awards totaling $136 thousand in combined potential value, though obligated dollars across those awards reached $480 thousand — a signal of earlier-stage work or staged funding. The firm operates across three NAICS categories — Fabricated Structural Metal Manufacturing, Machine Shops, and Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing — reflecting mission-critical equipment roles in ship systems and aeronautical platforms.
The vendor's customer base is defense-heavy: the Department of the Navy Naval Sea Systems Command (two awards), the Department of the Navy Naval Air Systems Command Naval Air Warfare Center ($136 thousand potential value), the Department of Homeland Security U.S. Coast Guard, and the Defense Advanced Research Projects Agency each hold recent awards. As a subcontractor, Johansing Iron Works delivers heat exchangers and custom-fabricated metal skids to Raytheon Company on CIWS production and overhaul work (May 2026 and September 2024 awards) and to Sri International on the Phase 3 Rational Integrated Design of Energetics (RIDE) program (March 2024 award). Two prime awards complete the footprint, one issued by the Naval Air Systems Command and one by the Coast Guard. Award activity is episodic — one award in 2018, one in 2019, two in 2024, one in 2026 — with no discernible recompete cliff in the near term given the small and scattered portfolio.
