TheUrsa Major Technologies Hadleyis a 22-kilonewton (5,000 lbf) thrustKerosene/LOXoxidizer-richstaged combustion cyclerocket engine.
Hadley is the first engine developed byUrsa Major Technologies.It started development in 2015, and prototypes were test fired in 2018.[1]In March 2022 qualification of the engine was complete and flight-ready engines had been delivered to customers.[2]In March 2024Stratolaunch Systemsannounced completion of the first powered flight of theTalon-Atest vehicle, TA-1.[3]Hadley is the engine powering Talon-A.[4]
Another initial customer,Phantom Space Corporation,plans to use Hadley on their Daytona small-lift rocket.[2]ABL Space Systemsinitially announced they would use the Hadley engine for theupper-stage[1]of theirRS1 rocket,but have subsequently decided to use an internally-developed engine called E2.[5]In April 2023,Astrasuggested the vacuum variant of the Hadley engine would power the second stage of their Rocket 4.0 launch vehicle.[6]
