According to Castelion, the framework agreement also includes a pathway for the Department of War to procure thousands of additional missiles in the future. The company stated that the programme is intended to support the department’s “Arsenal of Freedom” initiative focused on expanding large-scale deterrence capabilities.
Castelion described the agreement as the first production arrangement of its kind for a low-cost hypersonic weapon system. The company stated that the programme is intended to accelerate the deployment of operational hypersonic strike capabilities for U.S. forces.
Bryon Hargis, chief executive officer and co-founder of Castelion, said, “We’re grateful to the Department of War for this commitment to bring Blackbeard’s hypersonic strike capability to our warfighters.”
“It’s a clear signal that hypersonic weapons are crucial to the future, and Castelion is dedicated to accelerating production,” Hargis added.
According to the company, Blackbeard is designed as a low-cost hypersonic strike missile intended to support scalable production and operational deployment. Castelion stated that the framework agreement directly supports the Department of War’s objective of strengthening credible deterrence through expanded weapons manufacturing capacity.
The company did not disclose additional technical specifications or programme timelines beyond the production commitment outlined in the agreement. Castelion stated that missile production would begin after completion of testing and validation activities required for operational fielding.
