C
Overview
Castelion designs, tests, and manufactures hypersonic strike weapons for the U.S. military. Its flagship Blackbeard is a low-cost, mass-producible hypersonic missile compatible with HIMARS and MLRS, built in-house with solid rocket motors, propellant production, and a real-time, hardware-isolated flight computer. The company uses vertical integration and a rapid test-and-iterate cycle to enable fast, scalable production from day one, supported by its planned Project Ranger manufacturing campus. Its goal is to deter future wars through credible, non-nuclear deterrence by fielding advanced weapons quickly and at scale.
