Avio M10
Avio M10 development liquid rocket engine for the Vega-E upper stage. ESA describes a 10-tonne-class cryogenic liquid-oxygen/liquid-methane expander-cycle engine with multiple in-space stops and restarts, intended to replace Vega-C's Zefiro-9 and AVUM stages; the record remains development-stage with no flight asserted.
