Ursa Major Engine Powers Rapid-Development Hypersonic Demonstrator

According to a recent LinkedIn post from Ursa Major, the company’s Draper storable liquid rocket engine has been used on the first flight of the Air Force Research Laboratory’s Affordable Rapid Missile Demonstrator, reportedly achieving supersonic speeds and its intended objectives. The post also notes that Ursa Major acted as prime integrator for the entire vehicle for the first time, compressing the timeline from contract signature to flight into months rather than years.

The post suggests growing technical credibility for Ursa Major in defense-oriented propulsion and integrated vehicle delivery, which could strengthen its position in the U.S. hypersonic and high-speed weapons supply chain. If this performance is validated and repeatable, the company may be better positioned for follow-on contracts tied to affordable mass production of high-speed systems for the warfighter, potentially improving revenue visibility and enhancing its competitive standing against larger aerospace incumbents.
