Raptor is a family of rocket engines developed and manufactured by SpaceX. It is the third rocket engine in history designed with a full-flow staged combustion (FFSC) fuel cycle, and the first such engine to power a vehicle in flight. [15] The engine is powered by cryogenic liquid methane and liquid oxygen, a combination known as methalox.

SpaceX discussed in October 2013 that they intended to build a family of methane-based Raptor rocket engines, [16] initially announcing that the engine would achieve 2.94 meganewtons (661,000 lbf) vacuum thrust. [16] In February 2014, they announced that the Raptor engine would be used on the Mars Colonial Transporter.
The Super Heavy booster is powered by 33 Raptor engines burning liquid methane and oxygen to generate more than 16 million pounds of thrust at full throttle, more than twice the liftoff power of ...
At its base are 33 Raptor engines, which together produce 16.7 million pounds of thrust — about double the 8.8 million pounds of thrust of NASA’s Space Launch System rocket, which launched for ...
The 30-foot-wide Super Heavy first stage, loaded with 6.8 million pounds of liquid oxygen and methane propellants, stands 230 feet tall and is powered by 33 SpaceX-designed Raptor engines ...
The Raptor engine uses a full-flow staged combustion cycle with oxygen and methane-rich turbopumps. [27] [28] Before 2014, only two full-flow staged-combustion rocket engine designs had advanced enough to undergo testing: the Soviet RD-270 project in the 1960s and the Aerojet Rocketdyne Integrated Powerhead Demonstrator in the mid-2000s.
