My First True Rocket Booster/Engine
Make it as a sub-assembly for your rocket projects :)

Raptor is a family of cryogenic, methane-fueled rocket engines under development by SpaceX. The engines are powered by densified liquid methane and liquid oxygen (LOX), rather than the RP-1 kerosene and LOX used in all previous Falcon 9 rockets which use Merlin 1C & D engines. The earliest concepts for Raptor considered liquid hydrogen (LH
2) as fuel rather than methane. The Raptor engine will have two to three times the thrust of the Merlin 1D engine that powers the current Falcon 9 launch vehicle.

The broad Raptor concept "is a highly reusable methane staged-combustion engine that will power the next generation of SpaceX launch vehicles designed for the exploration and colonization of Mars".According to SpaceX founder Elon Musk, this design will be able to achieve full reusability of all rocket stages and, as a result, "a two order of magnitude reduction in the cost of spaceflight"
