Ursa Major Technologies is an independent developer and manufacturer of liquid rocket engines for the space launch, hypersonics, and defense sectors. Based in Berthoud, Colorado, the company was founded in 2015 to address the need for flexible, cost-effective propulsion with faster production cycles than traditional aerospace suppliers. Its proprietary use of metal powder bed fusion (LPBF) enables high design flexibility and reduced part counts, compressing engine development and delivery timelines.
The company's core product line includes the Hadley engine, a liquid oxygen and kerosene design, and the Arroway methane-LOX engine. These engines serve a range of applications from small satellite launchers to hypersonic testbeds. Ursa Major's additive manufacturing approach allows it to produce complex geometries that would be impossible or prohibitively expensive with conventional machining, and to iterate designs rapidly in response to customer requirements.
Ursa Major's customer base spans the U.S. Department of Defense, defense prime contractors, and commercial launch providers. Notable partnerships include the U.S. Air Force Research Laboratory, the U.S. Navy, the U.S. Space Force, Stratolaunch, and Phantom Space. In 2023, the company secured a large commercial engine order from Phantom Space and delivered engines to Stratolaunch for its hypersonic testbed. The company also expanded its R&D footprint with a site in Youngstown, Ohio in 2024.
Ursa Major competes with vertically integrated players such as Blue Origin, SpaceX, and Rocket Lab, as well as legacy propulsion houses like Aerojet Rocketdyne. Its differentiation lies in focusing exclusively on propulsion hardware and leveraging metal LPBF to offer faster, more flexible production. The company has raised approximately $493 million from investors including Explorer 1 Fund, Eclipse Ventures, and RTX Ventures. A key open question is whether its independent engine supply model can scale to compete with the internal propulsion capabilities of major launch integrators.
