- On May 1, 2025, Ursa Major received a $28.6 million contract from the Rocket Propulsion Division at Edwards Air Force Base to develop propulsion systems for responsive space and hypersonic applications.
- This contract builds on prior work to advance liquid rocket engines and aims to develop a flight demonstration for hypersonic, responsive space, and on-orbit propulsion.
- Ursa Major's Draper engine combines the storability of solid motors with the throttle control and range of liquid systems and recently completed over 200 hot-fire tests.
- The Draper engine, producing 4,000 pounds of thrust and using storable, non-cryogenic propellants, is designed to support hypersonic missile applications with cost-effective manufacturability, according to CEO Dan Jablonsky.
- Ursa Major has been selected to oversee the integration of a flight demonstrator featuring its Draper engine, supporting advancement of U.S. Hypersonic weapon technologies within a project scheduled through early 2027 amid heightened strategic competition.
