A Torrance Startup Raised $1B for Hypersonic Missiles. The Factory Is in New Mexico.

dot.LA reported the round at a $13 billion valuation on August 21, 2026. The missile, Blackbeard, is designed in California and built in New Mexico.

Castelion, a defense company based in Torrance, has raised $1 billion to move a hypersonic missile from prototype to mass production. The round is a Series C valuing the company at $13 billion, dot.LA reported on August 21, 2026. What that reporting does not carry, and what this desk has not read, is the underlying paperwork: no SEC Form D for the round, no Torrance building permit for a production line, no contract number.

The gap is the story's whole difficulty. A funding announcement is a company describing itself. A factory schedule for a weapon the federal government has to buy, test and field is something else, and it lands on a South Bay workforce that has spent decades building hardware for exactly one customer.

What the round is made of

The financing, as dot.LA described it, is $800 million in equity plus a $250 million revolving credit facility. Those two components add to $1.05 billion, against a round the outlet describes as $1 billion. JPMorganChase's Strategic Investment Group, Andreessen Horowitz and Carlyle co-led. Lightspeed Venture Partners, Lavrock Ventures, Altimeter, General Catalyst, T. Rowe Price and the Los Angeles firm Interlagos Capital also participated, the outlet reported.

The production floor is 1,000 acres away from Torrance

The missile is called Blackbeard, and dot.LA describes it as a low-cost hypersonic strike weapon designed in California and built in New Mexico. Hundreds of millions of dollars from the round will go toward expanding manufacturing at Project Ranger, the company's 1,000-acre production campus in New Mexico, the outlet reported. The engineering stays in Los Angeles County. The floor space does not.

Announced August 21, 2026. In service, on the company's own schedule, in 2027.

The federal customer, as the company describes it

Castelion says it has secured more than $500 million in U.S. military contracts over the past 18 months and moved Blackbeard from a clean-sheet concept to an official program in fewer than four years, dot.LA reported. Those are the company's figures. The reporting does not name the contracting agencies, the award numbers or the obligation dates, and this desk has not pulled the federal spending records or a SAM.gov registration. A company-stated contract total and an obligated federal dollar are not the same measurement.

Castelion is not the only defense manufacturer in the region raising at this scale. Neros, an El Segundo drone company, raised a $250 million Series C at a $2.5 billion valuation, dot.LA reported on August 14, 2026, with participation from Interlagos, the same Los Angeles firm listed in the Castelion round.

What would answer the open questions

Three documents would move this story from a company's account to a record:

• The SEC Form D for the Series C, which would list the amount actually sold, the date of first sale and the number of investors.
• Federal contract records tying the $500 million figure to specific awards and agencies.
• Torrance or Los Angeles County permits showing what, if anything, is being built at the Torrance site rather than in New Mexico.

None of those were part of the reporting summarized here. Until they are, the $13 billion valuation is a price investors agreed to pay, and the 2027 service date is a plan.
