The TQ-12 (Chinese: 天鹊-12; pinyin: Tiānquè-12, lit. Sky Lark 12) is a gas-generator cycle rocket engine burning liquid methane and liquid oxygen (methalox) developed by LandSpace.[4] TQ-12 is the first Chinese liquid rocket engine developed with private funding.[5] The engine has been designed to produce 670 kilonewtons (150,000 lbf) of thrust at sea level.[6]
