Castelion: Company Profile & Valuation

Castelion, founded in late 2022 and based in Torrance, California, designs, tests and manufactures next-generation military systems, focusing on affordable, mass-producible hypersonic strike weapons. Its lead product, Blackbeard, is the company's first low-cost hypersonic strike missile, moving from a clean-sheet design to a program of record in under four years.

The company built its first solid rocket motor and flight computer in-house and completed its first flight test in the Mojave Desert in 2024. In 2026, the U.S. Navy awarded Castelion $90 million to advance Blackbeard toward Early Operational Capability, alongside earlier delivery orders for pre-production prototypes.
