It is the third full-flow staged combustion rocket engine designed in the world and the first to be used for flight. It uses liquid methane and liquid oxygen as propellants (also known as liquid oxygen methane). SpaceX's heavy-lift rocket Starship uses the Raptor engine in its Super Heavy booster and Starship spacecraft. Starship's mission includes delivering payloads to Earth orbit, as well as future planned lunar and Mars missions. The Raptor engine has a thrust of about three times that of SpaceX's Merlin 1D engine used for Falcon 9. It is designed to be reused after a small amount of maintenance.
