Blackbeard Mach 5 hypersonic missile wins $90M US Navy deal, targets $500K per round

Castelion has secured an $89.99 million U.S. Navy order to move its Blackbeard hypersonic strike weapon toward Early Operational Capability. The California defense startup revealed Blackbeard publicly on August 20. Just days later, the Navy awarded funding for 50 Early Operational Capability weapons. The firm-fixed-price award signals a major shift for the program. Blackbeard must now prove it can move beyond flight testing and into repeatable production. Castelion will provide engineering, technical, logistics, and manufacturing support under the order. The work will also support Blackbeard’s transition into a formal Navy Program of Record. Production will take place in Torrance, California. Castelion expects to complete the work by August 2028. Towards operational service Blackbeard takes a different approach from many earlier U.S. hypersonic programs. Castelion designed the weapon around manufacturing scale from the beginning. The company aims to produce large numbers of weapons without relying on low-volume production methods. The compact strike weapon uses vertically integrated propulsion and guidance systems. Castelion says Blackbeard can exceed Mach 5 and strike targets up to 500 nautical miles away. That range could give U.S. forces a new standoff option against heavily defended targets. The Navy initially examined the weapon for land-based applications. Its potential role has since expanded toward carrier aviation. Castelion has positioned Blackbeard for integration with the Navy’s F/A-18E/F Super Hornet fleet. That could give carrier air wings a hypersonic weapon designed for rapid launches against distant targets. Modern anti-access and area-denial networks increasingly threaten aircraft operating near contested waters. Longer-range weapons can allow naval aircraft to strike from outside some defensive zones. Blackbeard’s speed could further reduce the time available for an opponent to detect, track, and respond. Different hypersonic model Cost sits at the center of Blackbeard’s design philosophy. Many hypersonic weapons involve highly specialized components and limited production runs. Those systems can cost millions of dollars per weapon. Castelion instead aims to keep Blackbeard below $500,000 per round. The weapon makes a deliberate tradeoff to pursue that goal. It carries a smaller payload than larger hypersonic systems but targets much greater production volume. That approach could matter on aircraft carriers, where magazine depth remains a major operational concern. A lower-cost weapon could allow the Navy to field more hypersonic rounds across its carrier air wings. Higher inventories could also support repeated conventional strikes during a prolonged conflict. The new order also funds Defense Exportability Features for Blackbeard. Those modifications could help accelerate future sales to U.S. allies and partners. Export versions would require designs that meet American technology protection requirements. Castelion’s new Navy award does not guarantee Blackbeard’s entry into full-rate production. The program still faces engineering, manufacturing, and operational milestones. Still, funding for 50 Early Operational Capability weapons gives the startup a clearer path toward deployment. Blackbeard has already flown. Now Castelion has to build 50 of them. That transition will test whether the startup’s manufacturing-first approach can work outside prototypes and small test batches.Get the latest in engineering, tech, space & science - delivered daily to your inbox.Aamir is a seasoned tech journalist with experience at Exhibit Magazine, Republic World, and PR Newswire.
