Stellios Technologies is a defense and energy company designing and building the next generation of American power systems. We started Stellios to ensure the United States leads the next power frontier -- and restores America's historic dominance in high-energy power systems. Our platform spans directed energy, high-power microwaves, and the foundational technologies that will define the next century of defense and propulsion. We are vertically integrated -- generating extreme power, conditioning it, and applying it across defense, propulsion, space, and energy. We have deep technical roots in the technologies that matter: vacuum HPM devices, high-voltage modulators, gyrotrons, klystrons, and power supplies that operate at the frontier of what is technically possible.
