Castelion hits $13B valuation to mass-produce hypersonic missiles

Castelion, a missile startup founded by former SpaceX executives, has raised a $1 billion Series C at a $13 billion valuation. The round was co-led by Andreessen Horowitz, Carlyle, and JPMorgan Chase.

Founded in 2022, Castelion set out to manufacture hypersonic weapon systems at a lower cost and at faster speeds than traditional defense primes. Since then, the startup has secured more than $500 million in U.S. military contracts.
