About the company
Castelion Corporation, a small business defense contractor headquartered in Torrance, California, delivers advanced defense technology research and development, rapid prototyping, and weapons manufacturing to the Department of Defense as a prime contractor across multiple indefinite delivery vehicles and definitive contracts. The company competes exclusively in full-and-open procurements with no set-aside designations on its largest vehicles, though it qualifies for and has won several total small business set-aside definitive contracts valued under $20 million; the company is structured as a for-profit manufacturer with no disclosed SBA certifications (8(a), HUBZone, SDVOSB, WOSB).
Castelion's capability portfolio centers on hypersonic weapon systems, advanced radar development, long-range strike weapons manufacturing, and rapid cargo delivery mechanisms. Recent representative work includes a $55.8 million Air Force Research Laboratory delivery order (awarded October 2024, completing November 2026) for low-cost, highly manufacturable long-range strike weapon production under SBIR Phase III; a $16.97 million AFRL SBIR Phase II contract (awarded September 2023, completing April 2027) for the Future Operational Capabilities for the US (FOCUS) low-cost missile program; a $1.99 million Missile Defense Agency total small business set-aside for Compact Hypersonic Missile/Effector Reactive Material (CHYMERA) warhead prototype and demonstration (awarded September 2025, completing September 2027); and a $1.4 million AFRL total small business set-aside for KU-Band Affordable Resiliently Manufactured Active Electronically Scanned Array (KARMA) radar development (awarded April 2025, completing April 2027).
Customer concentration skews heavily to the Air Force and Navy on dollars, despite a more distributed award count across nine customer agencies. The Department of the Air Force Lifecycle Management Center's Eglin Air Force Base commands the potential-value rankings with a single $46 billion multiple-award Indefinite Delivery Indefinite Quantity vehicle (Eglin Wide Agile Acquisition Contract, awarded September 2023, performing through September 2031), though only one task order against it appears in recent awards. The Department of the Navy Naval Air Systems Command's Naval Air Warfare Center anchors the second tier with two awards totaling $155 million in potential value, including a $154.99 million Total Small Business set-aside delivery order (awarded February 2026, completing April 2028) and a Naval Air Warfare Center Basic Ordering Agreement with $0 ceiling (awarded January 2026, performing through January 2031 as a funded-as-ordered SBIR Phase III vehicle). The Department of the Army awarded a $120 million Other Transaction IDV for the BLACKBEARD GL Prototype Project Phase 1 (awarded September 2025). The Air Force Research Laboratory accounts for four awards totaling $75.9 million in combined potential value across SBIR and non-set-aside definitive contracts.
Activity accelerated sharply in 2025 with seven awards, up from two in 2024 and four in 2023. Six awards carrying combined potential value of $233 million face ultimate completion or recompete within the next twenty-four months. The company holds positions on four major vehicles: the $46 billion Eglin Wide Agile Acquisition Contract (Air Force), the $120 million Army Other Transaction IDV for BLACKBEARD GL, a Naval Air Warfare Center Basic Ordering Agreement structured for SBIR Phase III prototyping and production, and the $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ awarded by the Missile Defense Agency (December 2025, performing through December 2035) with full and open competition. Castelion operates exclusively as a prime contractor across its federal footprint with no disclosed subcontractor relationships; all fifteen awards in the source data are prime awards. Work is performed at company facilities in Torrance and El Segundo, California, and Arlington, Virginia, with one award naming Huntsville, Alabama as place of performance.
