Castelion Raises $1 Billion for Blackbeard Hypersonic Missile
U.S.-based hypersonic missile startup Castelion has closed a $1 billion Series C funding round to scale production of its Blackbeard weapon. The round pushes the company’s valuation to $13 billion.
At a Glance
- Funding: $1 billion ($800 million equity + $250 million revolving credit facility)
- New valuation: $13 billion
- Investors: co-led by Andreessen Horowitz, Carlyle, and JPMorgan Chase
- Product: Blackbeard hypersonic missile, priced at roughly $384,000 per unit
- Manufacturing site: Project Ranger Campus, Sandoval County, New Mexico — the largest dedicated hypersonic missile manufacturing facility in the U.S.
- Founders: Bryon Hargis, Sean Pitt, Andrew Kreitz (former SpaceX executives)
- Pentagon framework: a two-year plan requiring at least 500 missiles per year (May 2026)
Background
The funding round, announced August 20, 2026, will finance expanded production of Castelion’s Blackbeard hypersonic missile and the development of longer-range strike and defensive weapons. Of the total, $800 million is structured as equity and $250 million as a revolving credit facility, with Andreessen Horowitz, Carlyle, and JPMorgan Chase co-leading the round.
The company will significantly expand manufacturing capacity at its 1,000-acre Project Ranger Campus in Sandoval County, New Mexico — described as the largest dedicated hypersonic missile manufacturing facility in the country. Castelion was founded by three former SpaceX executives, Bryon Hargis, Sean Pitt, and Andrew Kreitz, and has secured more than $500 million in U.S. military contracts to date.
Blackbeard is expected to cost roughly $384,000 per missile, a figure that reflects a notably low-cost target compared with traditional hypersonic weapons programs. A framework agreement the Pentagon signed in May 2026 outlines a two-year production plan requiring at least 500 missiles per year, contingent on the weapon successfully clearing testing and validation.
What It Means for Türkiye
Castelion’s low-cost, high-volume production model shows that global competition in hypersonic weapons is no longer limited to state-backed defense giants, as private-sector ventures increasingly enter the field. For Türkiye’s own hypersonic and long-range missile efforts led by Roketsan, this development offers a precedent for how reducing per-unit production cost can create a competitive advantage in the transition to serial manufacturing. The growing appetite of U.S. private capital for defense-tech startups also offers a reference point for how a similar private-investment-meets-state-contract model could function within Türkiye’s own defense industry ecosystem.
