Castelion Wins $23.4 Million US Navy Order for 50 Blackbeard Hypersonic Strike Weapon Prototypes

Technical Summary

The United States Navy has placed a 23.35 million US dollar firm-fixed-price order with Castelion Corporation of Torrance, California for 50 early operational capability (EOC) pre-production prototypes of a low-cost long-range strike weapon, together with 50 storage and shipping containers. The order (N6833526F1138), listed in the U.S. Department of War contract digest of 11 June 2026, was placed against an existing basic ordering agreement (BOA) and funded with fiscal year 2026 Research, Development, Test and Evaluation (RDT&E) (Navy) money. Work is split between Rio Rancho, New Mexico (75 per cent) and Torrance, California (25 per cent), with completion expected in December 2027. The Naval Air Warfare Center Aircraft Division (NAWCAD) at Lakehurst, New Jersey is the contracting activity. The award falls under Small Business Innovation Research (SBIR) Phase III topic AF231-D026, titled ‘Low Cost Highly Manufacturable Long Range Strike Weapon Production’, and is described in the listing as advancing the key enabling technology for a rapidly fieldable hypersonic weapon system.

The weapon behind the SBIR effort is Blackbeard, Castelion’s low-cost hypersonic strike weapon, which the company has positioned as a design engineered from the outset for industrial-rate output and commercial unit cost rather than exquisite, low-volume manufacture. The 11 June order is the production-prototype step in a fast-moving programme. In February 2026 the Navy awarded Castelion a 49.9 million US dollar contract to advance Blackbeard from prototype toward early operational capability. On 24 April 2026 it added a 105 million US dollar award to integrate the weapon onto the F/A-18E/F Super Hornet and to clear the system-safety and airworthiness certification needed for carriage from an aircraft carrier, with early operational capability targeted in 2027. On 13 May 2026 the company and the Department of War signed a production framework agreement covering a guaranteed minimum of 500 missiles per year once test and validation is complete, with a stated pathway to thousands more. Castelion closed a 350 million US dollar Series B financing round in December 2025 and is building a dedicated production campus, Project Ranger, in Sandoval County, New Mexico, the county that contains the Rio Rancho work location named in this order.

The order covers 50 early operational capability prototypes and 50 storage and shipping containers, and sits beneath a May 2026 framework agreement for a guaranteed minimum of 500 Blackbeard missiles a year once testing is complete. U.S. Department of War contract listing and Castelion, June 2026

Analysis of Effects

The procurement signal is mass at low unit cost. Hypersonic weapons have historically been fielded in small numbers at very high price, which limits magazine depth in any sustained campaign. The structure of this order points the other way. A pre-production run of 50 all-up rounds with matching containers is the step at which a design transitions from flight-test articles into a manufacturable, storable and transportable munition. The inclusion of 50 storage and shipping containers in the same order is the detail that matters most to ammunition managers, because it signals an intent to handle, store and move the rounds as classified energetic items rather than hold them as one-off test assets.

For the energetics base, a boosted long-range strike weapon places demand on solid rocket motor propellant, warhead explosive fill and the qualification capacity that sits behind both. A rapidly fieldable hypersonic round still has to clear the same hazard classification, insensitive munitions (IM) assessment and propellant qualification gates as any other energetic store before it can be stockpiled at scale, and those gates are usually the long pole in a production ramp. The open question is whether the qualification and safety-case work is keeping pace with the manufacturing ambition, or whether the prototype containers are an interim measure ahead of a settled classification.

Personnel and Safety Considerations

For storage and transport planners the relevant articles are complete long-range strike rounds with an integral rocket motor and a warhead, packaged in the 50 containers named in the order. A boosted munition of this class would normally attract Hazard Division (HD) 1.1 or HD 1.2 with an appropriate Compatibility Group (CG) depending on the motor propellant and warhead fill, but the formal classification for these prototypes is a DATA GAP and should not be assumed. Net Explosive Quantity (NEQ) per round and per packaged container is not disclosed and must not be inferred from the contract value. Until a transport classification is assigned under the United Nations Recommendations on the Transport of Dangerous Goods and adopted into the national competent authority listing, and until storage quantity-distance is set under the US Defense Explosives Safety Regulation (DESR 6055.09) or, for allied handling, NATO Allied Ammunition Storage and Transport Publication AASTP-1 (Edition C), prototype rounds of this type are handled under conservative provisional assumptions. Solid-propellant production scale-up itself carries process-safety obligations that grow with throughput.

Data Gaps

The following are not available in open sources at the time of writing: the launch mode and host platform specific to the 50 prototypes in this order, since the Navy’s separate integration effort centres on carrier air-launch from the F/A-18E/F Super Hornet while Blackbeard has also been reported in an Army ground-launched context, leaving the configuration of these particular rounds unconfirmed; the warhead type and explosive fill; the propellant type and motor configuration; the official Net Explosive Quantity per round and per container; the formal Hazard Division and Compatibility Group assignments; the achieved or target range and terminal velocity; and the unit cost the ‘low cost’ descriptor refers to. Confidence in the order value, quantity and contracting facts is high (a Tier 1 government primary source); confidence in weapon-level performance and classification is low pending disclosure.
