The Ursa Major Technologies Hadley is a 22-kilonewton (5,000 lbf) thrust Kerosene/LOX oxidizer-rich staged combustion cycle rocket engine.
Hadley is the first engine developed by Ursa Major Technologies. It started development in 2015, and prototypes were test fired in 2018.[1] As of March 2022, qualification of the engine is complete and flight-ready engines have been delivered to customers.[2]
Initial customers of the Hadley engine include Stratolaunch Systems, which has announced that they will use the Hadley engine on their Talon-A hypersonic test vehicle, and Phantom Space Corporation, who will use it on their Daytona small-lift rocket.[2] ABL Space Systems initially announced they would use the Hadley engine for the upper-stage[1] of their RS1 rocket, but have subsequently decided to use an internally-developed engine called E2.[3] In April 2023, Astra revealed that the vacuum variant of the Hadley engine would power the second stage of their Rocket 4.0.[4]
