P120 is a solid-fuel first-stage rocket motor developed by Avio and ArianeGroup through the joint venture Europropulsion on behalf of European Space Agency for use on Vega C and Ariane 6.[2]
"C" in P120C stands for "Common" as it will be shared by Ariane 6 and Vega-C.[3]
In July 2022, with its inaugural flight, it replaced its predecessor P80 as the world's largest and most powerful one-piece solid-fuel rocket motor.[4]
