Ariane 6
Ariane 6 is designed with two core stages. They are both powered by liquid hydrogen-liquid oxygen (hydrolox) engines. The first stage has a version of the Vulcain engine that is used on the Ariane 5. The second stage has a new design of the Vinci engine. Most of the lift-off thrust comes from solid rocket boosters attached to the first stage. There are two P120s on the Ariane 62 and four on the Ariane 64 variants. These are larger versions of the P80s used on the Vega rocket.
