- Castelion said the financing values the four-year-old startup at $13 billion.
- The new investment will boost planned production of Blackbeard, Castelion’s hypersonic missile, and fund development work on a bigger hypersonic strike weapon and a mass-produced air-defense missile.
- Castelion is a defense-tech startup seeking to mass produce lower-cost hypersonic weapons and has raised more than $1 billion in new financing to expand missile production.
- The funding will expand production of Blackbeard at its manufacturing complex in Sandoval County, New Mexico, while accelerating work on a longer-range precision strike weapon and defensive systems.
- The initial fielding of Blackbeard is targeted for 2027, with the U.S. Navy emerging as its main customer.
- The U.S. Navy awarded Castelion about $50 million in February to advance Blackbeard, followed by a $105 million award in April for integration, testing, and certification on the F/A-18E/F Super Hornet.
- In June, the Navy placed a $23.4 million order for 50 pre-production Blackbeard weapons and 50 shipping and storage containers.
- Blackbeard is expected to cost roughly $384,000 per missile, significantly less than existing U.S. hypersonic weapons.
