About

Castelion is a defense startup developing the Blackbeard hypersonic missile system, one of the few startups with an active US Navy contract for hypersonic weapons full-scale prototyping and early operational fielding. The company raised $350 million in Series B financing in December 2025 and secured a $50 million US Navy contract for Blackbeard prototyping, directly addressing the DoD's urgency to field hypersonic strike capability as China and Russia have demonstrated operational hypersonic weapons.
