Ursa Major Technologies, Inc. ("Ursa"Â) is a designer and manufacturer of the highest performing, lowest cost, and most reliable rocket engines for the space launch and hypersonic markets. Ursa proposes the initial steps in the development of a 50,000 lbf liquid oxygen/hydrogen fuel rich staged combustion rocket engine for upper stages on medium and heavy lift launch vehicles. The engine will provide an increased performance domestic source replacement for the RL-10, the legacy upper-stage engine currently slotted for the majority of next generation launch vehicles serving the Air Force's National Security Launch Missions as well as the NASA Space Launch System ("SLS"Â). The engine will utilize the latest in 3D printing and agile engine development to deliver 2x the thrust of an RL-10 at a production price per pound of thrust 10x lower
