Ursa Major’s storable liquid rocket engine technology is revolutionizing hypersonic propulsion for the U.S. Air Force, offering unprecedented maneuverability and operational flexibility. Unlike traditional solid-fuel and air-breathing systems, the company’s Draper engine can start, stop, and throttle mid-flight while operating in both atmospheric and space environments. Advanced 3D printing manufacturing techniques enable rapid development cycles and cost-effective production, positioning the U.S. to close the hypersonic gap against peer adversaries. The technology supports both tactical weapons systems and next-generation space capabilities.
