About Castelion Corporation

Castelion develops and manufactures long-range hypersonic strike systems to address a critical gap in U.S. defense capability, where the nation has fallen behind near-peer adversaries in hypersonics technology. Headquartered in Torrance, California, with a production facility in Rio Rancho, New Mexico, the company is transitioning from prototype development to scalable production with an ambitious goal of manufacturing thousands of units per year. Operating on a fully on-site model with a five-day-per-week requirement, Castelion is positioned to become a key supplier of advanced defense systems for the U.S. military.
