Building Long-Range Hypersonic Missiles: A Conversation with Bryon Hargis of Castelion
Castelion is one of those companies that feels like it belongs to the future but is being built, urgently, in the present. Cofounder and CEO Bryon Hargis talks about hypersonic missiles the way great engineers talk about first principles - clean, direct, unembellished. Deterrence in a can. Simple words for an undertaking that is anything but.
What emerges in this interview isn’t hype. It’s clarity. Castelion is rebuilding a capability the U.S. quietly lost: the ability to design, manufacture, and field strategic systems at speed. No theatrics, no hand-waving - just disciplined engineering aimed at restoring deterrence through real hardware.
It’s worth watching the conversation. Not because it’s flashy, but because it’s a rare glimpse into the mindset of a team working on problems that actually matter.
