YF-209

YF-209 is a development-stage Chinese liquid-oxygen/liquid-methane rocket engine for commercial launch applications. China’s National Space Administration reports 780 kN vacuum thrust, deep throttling, at least three mission starts, and a target of at least 30 reuses; the last two are capability and target statements, not evidence of serial production or completed reuse. The source identifies China Aerospace Science and Technology Corporation’s Sixth Academy as the presenting organization; no narrower manufacturer attribution is asserted here.
