Ursa Major wins Air Force contract for hypersonic, space launch engine

The U.S. Air Force Research Laboratory awarded Colorado-based propulsion company Ursa Major a contract to mature two engines, one for space launch and the other for hypersonic launch.

Under the contract, the company will continue the development of its 200,000-pound thrust Arroway engine for space launch, which Ursa Major unveiled in June 2022. Arroway will help replace the Russian-made RD-series engines, according to a company press release. It is a reusable liquid oxygen and methane staged combustion engine for medium and heavy launch vehicles, and the company expects to conduct a hot fire test in 2025.
