Ursa Major has been awarded a $32.9 million contract to develop and deliver 16 upgraded Hadley H13 engines to Stratolaunch. The multi-year program extends a series of successful flight collaborations and supports a growing operational cadence.
Dan Jablonsky, CEO of Ursa Major, said, "This contract directly supports U.S. hypersonic test infrastructure and the broader imperative to accelerate high-speed flight programs that deliver for national security. As the proud partner and hypersonic propulsion provider to Stratolaunch, we're focused on getting real capability into the field – faster, at scale, and without compromising performance."
The Hadley H13 is a mission-upgraded variant that increases engine reusability with additional starts, driving down cost per flight while supporting new test objectives and mission profiles.
Ursa Major's Hadley engines have powered multiple successful Talon-A missions, including sustained Mach 5+ flight and vehicle recovery, demonstrating the engine's performance under operational conditions.
