Ursa Major Technologies is an American aerospace company founded in 2015 and based in Berthoud, Colorado. The company produces rocket engines and sells them to space launch and hypersonics companies, and the U.S. Government.
The company makes a 5,000-pound thrust liquid oxygen and kerosene Hadley engine, named after a character in Ray Bradbury's The Veldt.[1] It also develops the Ripley engine, with 50,000 pounds of thrust, aimed at the medium-launch market.[2]
Its commercial customers include C6 Launch Systems, a Canadian small satellite launcher, and U.S. launch startup Phantom Space.[3] It also works with Generation Orbit Launch Services and with Stratolaunch.[4]
In 2017, Ursa Major raised $8 million last with participation from the Space Angels Network.[5]
In December 2021 the company closed its largest funding round to date: an $85 million Series C led by funds and accounts managed by BlackRock.[6]
