The YF-209 is a liquid cryogenic rocket engine burning liquid methane and liquid oxygen in a gas-generator cycle. The engine is designed for reusability and commercial use and is currently under development as of May 2024.

History

The YF-209 is designed for the commercial launch market in China with reusability in mind.[2] It can be reused at least 30 times and can be restarted at least 3 times during the mission with deep throttle capabilities.[3] The engine hot fire test was successfully completed in February 2023.[4] Development has been prioritised in 2024 to meet the growing needs of the commercial launch market.[5]
