The U.S. Navy is preparing to put its first Blackbeard hypersonic missiles on F/A-18 Super Hornets, a move that would give carrier air wings a standoff strike weapon built for volume production rather than limited-run procurement. Castelion Corporation, a newer entrant in the defense industrial base, holds a Small Business Innovation Research contract tied to a long-range strike weapon designed around scalable manufacturing and flight testing. A separate Department of War agreement with the same company targets low-cost hypersonic solutions at production rates the military has struggled to reach with legacy programs.
Blackbeard on the Super Hornet: what the Navy gains and why speed matters
For years, the Pentagon has invested heavily in hypersonic weapons that travel at speeds exceeding Mach 5, but nearly every program has been dogged by high unit costs and thin production lines. The result is a small inventory of expensive rounds that commanders would hesitate to expend in anything short of a major conflict. Putting a weapon like Blackbeard on the F/A-18 Super Hornet, still the backbone of carrier air wings, would change that calculus if the per-unit price drops far enough for routine procurement.
Castelion’s approach centers on manufacturing methods that can scale. The company’s SBIR award, contract FA2385-23-C-B007, is tied to solicitation topic code AF231-D026 and describes work on a highly manufacturable long-range strike weapon that progresses through production and culminates in flight testing. The emphasis on manufacturability, rather than pure performance breakthroughs, signals that affordability and volume are the driving requirements.
The hypothesis that Castelion’s SBIR-driven process will cut per-unit costs enough for routine squadron carriage within five years is plausible on paper but unproven. No publicly available test data, range figures, or cost-per-round targets have been released. The SBIR record confirms the program’s intent to demonstrate scalable production, yet the gap between a successful flight test and a weapon qualified for fleet-wide use on carrier decks is significant. Integration with the Super Hornet’s weapons stations, software, and fire-control system adds engineering and certification timelines that the public record does not address.
SBIR funding and Department of War framework agreements behind Castelion
Two distinct government actions anchor the Blackbeard effort. The first is the SBIR award itself. The federal SBIR program is designed to channel defense research dollars to small businesses with innovative technologies, and Castelion’s contract falls under that structure. The award abstract stresses that the program will produce a weapon at scale and validate it through flight testing, a sequence that moves beyond laboratory prototyping into hardware that can be evaluated under operational conditions.
The second action is broader. The Department of War announced framework agreements with new entrants, including a parallel agreement with Castelion, to advance low-cost hypersonic solutions. These frameworks are designed to expand U.S. strike capacity at scale, a phrase that reflects Pentagon concern about the gap between demand for precision munitions and the defense industry’s ability to deliver them in wartime quantities. The release describes experimentation and assessment campaigns paired with multi-year procurement structures, suggesting the department wants to lock in production commitments rather than fund one-off demonstrations.
Taken together, the SBIR contract and the framework agreement create two funding channels for the same company working on the same class of weapon. The SBIR path funds technology maturation and flight testing. The framework agreement positions Castelion for larger-scale buys once the weapon clears those milestones. That dual-track approach is unusual for a company of Castelion’s size and suggests the department sees enough promise to accelerate the timeline.
Gaps in the Blackbeard record: no test data, no Navy integration timeline
Several questions remain open. No primary Navy or Department of Defense record publicly confirms that Blackbeard has been formally selected for F/A-18 integration or that a program of record exists for fleet procurement. The SBIR abstract and the Department of War release contain no performance specifications, no range figures, and no flight-test results. Without those details, independent assessment of whether the weapon meets the Navy’s operational requirements is not possible.
No direct statements from Navy program officials address procurement quantities, delivery schedules, or the specific engineering work required to certify a new hypersonic weapon on the Super Hornet. The F/A-18E/F has carried a range of air-to-ground munitions over its service life, but adding a hypersonic round introduces thermal management, aerodynamic, and software challenges that differ from subsonic or supersonic weapons. How far along that integration work has progressed is not documented in any available public source.
Cost remains the central unknown. The entire premise of the Blackbeard effort is that a hypersonic weapon can be built cheaply enough to buy in bulk. Legacy programs in this class have struggled with unit costs that run into the tens of millions of dollars, making large-scale procurement politically and fiscally difficult. Castelion’s SBIR award explicitly targets manufacturability, but the company has not disclosed target price points or production rates.
