About Castheon Inc.
Castheon Inc., a for-profit precision manufacturer based in Thousand Oaks, California, delivers additive manufacturing, precision machining, and advanced fabrication services to the Department of Defense and NASA as both a prime contractor (60% of recent awards) and a subcontractor on defense propulsion and hypersonic weapons programs. The vendor competes under full-and-open competition with no set-aside designations; recent awards span research-and-development services, prototype development, and production of specialized aerospace and defense components.
Castheon holds a seat on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ issued by the Missile Defense Agency on January 21, 2026, with a multi-billion-dollar ceiling and performance extending through December 28, 2035. The contract encompasses advanced manufacturing, additive manufacturing, and precision machining for multi-domain defense systems across air, missile, space, cyber, and hybrid domains. One initial delivery order placed under SHIELD carries a $500 ceiling value. The vendor also places task orders under the Eglin Wide Agile Acquisition Contract (2 task orders) and an Indefinite Delivery Contract indexed HQ014718D0004 (1 task order).
Customer concentration skews toward defense and space agencies, with the top five customer segments accounting for 87% of award count. The Department of the Air Force Materiel Command Test Center anchors the dollar value ($2 million combined potential) despite representing only one award; NASA's Shared Services Center accounts for three awards ($298 thousand combined potential); the Missile Defense Agency holds four awards ($151 thousand combined potential); and NASA Marshall Space Flight Center carries two awards ($50 thousand combined potential). Recent capability examples include a $178,476 sole-source purchase order from NASA for C103 OHPACA parts (August 2024), a $74,000 purchase order for laser powder-bed fusion additive manufacture of C103 nozzle extensions (May 2023), and a $45,583 purchase order for 3D laser powder-bed fusion printing with stress relief and post-processing quality witness coupons (February 2023). Work is categorized primarily under Research and Development in the Physical, Engineering, and Life Sciences (7 awards) and secondarily under Ammunition Manufacturing and Machine Shops.
Activity accelerated in 2024, jumping from two awards in 2023 to seven in 2024, with two awards in 2026 to date. Castheon subcontracts to Raytheon Company on Hypersonic Attack Cruise Missile / Southern Cross Integrated Flight Research Experiment (HACM-SCIFIRE) programs involving non-complex machined components and additive manufacturing (November and August 2024); to RTX Corporation on Next Generation Propulsion cast conformal heat exchanger testing (June 2024); and to The Johns Hopkins University Applied Physics Laboratory on weapon systems technology engineering (May 2024). The vendor also receives sub-award work from the National Center for Defense Manufacturing and Machining on subcontracted services (June 2024).
