America's first Oxidizer Rich Staged Combustion engine, the Ursa Major Hadley is a 5,000 lbf sea level thrust, liquid oxygen and kerosene engine. Designed for full-envelope service and simple integration, the Hadley is a reliable engine solution for a wide range of vehicles in the orbital and suborbital launch regimes. Integrated fluid controls and electronic subsystems accompany this turnkey propulsion package for rapid customer utilization.
An evolution of the Hadley architecture, the Ursa Major Ripley engine is a 35,000 lbf class, liquid oxygen and hydrocarbon engine. Leveraging the manufacturing and design methodologies of the Hadley, Ripley is a competitive boost propulsion solution for a variety of "Venture class" vehicles, namely those sized to deploy approximately 150kg payloads to low earth orbit.
