Castelion Reaches $13 Billion Valuation to Scale Hypersonic Missiles
Castelion raised a $1 billion Series C at a $13 billion valuation to expand Blackbeard hypersonic missile production in New Mexico and challenge China's lead.
Summary
TechCrunch’s Marina Temkin reported at 12:01 p.m. PDT on August 20, 2026, that Castelion, a Torrance, California missile startup founded in 2022 by former SpaceX executives, raised a $1 billion Series C at a $13 billion valuation. Andreessen Horowitz, Carlyle and JPMorgan Chase co-led the round, with existing backers Lightspeed, General Catalyst and Altimeter participating. The financing included $800 million in equity and a $250 million revolving credit facility, components totaling $1.05 billion despite the stated $1 billion round.
Castelion, which has secured more than $500 million in U.S. military contracts, aims to manufacture hypersonic weapons faster and more cheaply than traditional defense primes. It will use the capital to produce Blackbeard missiles, named after the English pirate, and other hypersonic weapons at its New Mexico facility. The Pentagon wants more missiles capable of exceeding Mach 5 because the U.S. stockpile has not kept pace with China’s, and Castelion is betting its faster manufacturing process can narrow that gap.
Positives
- The $1 billion Series C lifted Castelion’s valuation to $13 billion four years after its 2022 founding.
- More than $500 million in U.S. military contracts gives Castelion substantial government demand for its weapons.
- $800 million in equity provides capital to expand Blackbeard and other hypersonic missile production.
- Andreessen Horowitz, Carlyle and JPMorgan Chase co-led the round, joined by Lightspeed, General Catalyst and Altimeter.
- The New Mexico facility is positioned to support the Pentagon’s push for more weapons capable of exceeding Mach 5.
Risks & concerns
- The U.S. hypersonic missile stockpile has failed to keep pace with China’s, according to the article.
- Castelion’s ability to close the stockpile gap still depends on its unproven bet that it can manufacture weapons faster.
- The financing includes a $250 million revolving credit facility, so the reported round is not entirely equity.
- The disclosed $800 million equity investment and $250 million credit facility total $1.05 billion, not the stated $1 billion.
