Notes[1][2]

The YF-130 is a Chinese rocket engine fueled by LOX and kerosene in an oxidizer-rich staged combustion cycle currently in development. It has been designed to reach around 500 tonnes of thrust and it will power the super heavy Long March 9 rocket.[3]

History

Chinese researchers completed a "half-system on full working condition" test of a YF-130 engine in March 2021, and expect to finish a whole-system test verification by the end of the year.[4] Full system test has been successfully completed on November 6, 2022.[5]
