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