(Ursa Major: Berthoud, CO) -- Ursa Major’s Hadley liquid rocket engine has completed 10 consecutive successful flights, including multiple missions at sustained hypersonic speeds, with Stratolaunch. The milestone underscores Ursa Major’s ability to deliver flight-proven, high-performing, reusable propulsion and defense systems at the speed and scale required for today’s national security environment.

Several of the 10 flights were conducted using previously flown Hadley engines, demonstrating reusability, durability, rapid turnaround, and a path to significantly lower cost per flight.

“These flights aren’t demonstrations; they’re operational test bed missions. Ten successful flights is proof that hypersonic capability is here,” says Chris Spagnoletti, CEO of Ursa Major. “Across Ursa Major, we design and build to fly, refly, and scale. That’s how we increase flight cadence, drive down cost, and deliver real systems to the field faster, giving the warfighter capability they can count on when it matters.”
