Castelion wins $105m Navy contract to integrate Blackbeard Hypersonic Missile on F/A-18

The U.S. Navy has awarded California-based defense startup Castelion a $105 million contract to integrate its Blackbeard hypersonic missile onto F/A-18 fighter jets, with fielding targeted for next year and a $250 million manufacturing campus under development.

Castelion, a small defense startup, has received a $105 million U.S. Navy contract to prepare its Blackbeard hypersonic missile for carrier-based F/A-18 fighter jets, according to government procurement disclosures posted on Friday. The award funds hardware and software integration, flight testing, and full system safety and airworthiness certification, the final major hurdle before the Navy decides on volume procurement.

This development matters because the United States is depleting its inventory of munitions that would be critical in a potential Taiwan conflict. Unlike land-based ballistic missiles, Blackbeard can be launched from carrier-deployed F/A-18s, placing Chinese missile sites and naval assets within reach that otherwise remain inaccessible. With speeds exceeding Mach 5 and a target unit cost around $384,000 low for hypersonic weapons, the missile could complicate adversary decision-making through affordable mass deployment.

Pentagon budget documents indicate the Navy plans to acquire 4,500 air-launched hypersonic missiles for F/A-18E/Fs over five years. Industries impacted include defense prime contracting, munitions manufacturing, and aerospace components.

Stakeholders include naval aviation commands, allied carrier operators, and traditional hypersonic incumbents facing disruption from startup entrants.

For investors, Castelion’s use of automotive-grade commercial components instead of military-spec space-rated parts, signals a cost-driven engineering model that could challenge established procurement paradigms. The company is privately funding Project Ranger, a $250 million New Mexico manufacturing campus expected to reach thousands of missiles annually by end of next year, with existing facilities across Texas, California, and Washington.

Castelion is a California-based defense technology startup focused on affordable hypersonic systems.

The U.S. Navy is the naval warfare service branch of the U.S. armed forces, operating carrier strike groups globally.
