\"Ursa<\/p>\n

Ursa Major<\/strong>\u2019s Hadley liquid rocket engine has completed 10 consecutive successful flights, including multiple missions at sustained hypersonic speeds with Stratolaunch<\/strong>. The milestone underscores Ursa Major\u2019s ability to deliver flight-proven, high-performing, reusable propulsion and defense systems at the speed and scale required for 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.<\/p>\n

\u201cThese flights aren\u2019t demonstrations; they\u2019re operational test bed missions. Ten successful flights is proof that hypersonic capability is here,\u201d said Chris Spagnoletti<\/strong>, CEO of Ursa Major<\/strong>. \u201cAcross Ursa Major, we design and build to fly, refly and scale. That\u2019s 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.\u201d<\/p>\n

The Hadley Engine is a flight-proven liquid oxygen (LOX)-based propulsion system designed for hypersonic applications and space launch. Built using advanced additive manufacturing, the engine enables rapid iteration, flexible design architectures and scalable production. This manufacturing approach allows Ursa Major to move from design to test to flight to production quickly and to continuously improve performance.<\/p>\n

As demand for hypersonic capability grows, Ursa Major remains focused on increasing flight cadence, scaling production and delivering reliable, American-made systems that strengthen the defense industrial base and meet evolving mission needs. Ursa Major is only the third company in the United States to prove and refly a reusable, hypersonic liquid rocket engine.<\/p>\n","protected":false},"excerpt":{"rendered":"
