Raptor has about triple the thrust of SpaceX's Merlin 1D engine, which powers the Falcon 9 and Falcon Heavy launch vehicles. Raptor was conceived to burn hydrogen and oxygen propellants as of 2009.

SpaceX has unveiled the Raptor 3 engine, marking significant advancements in thrust, specific impulse, and mass efficiency compared to previous versions. The Raptor 3 boasts a thrust of 280 tf, a specific impulse of 350s, and an engine mass of 1525 kg.
Due to the wider throat and increased chamber pressure, Raptor has gained a significant amount of thrust: Raptor 1 produced 185 tonnes of thrust while Raptor 2 produces 230 tonnes of thrust. The downside, though, of opening the throat is a ~1% decrease in ISP: Raptor 1 hit roughly 330 seconds of ISP while Raptor 2 reaches 327 seconds.
Each Raptor engine has a thrust of 230 ton-force (tf) or 507 kip-force (klbf). Considering the Super Heavy has 33 total engines, that means it's outputting 7,590 ton-force to get the...
The new Raptor 3 has a 280tf thrust, a 350s specific impulse, and an engine mass of 1525kg. This shows that SpaceX has managed to give the Raptor 3 a significant boost in thrust and...
To put this into perspective, the Raptor 2 rocket engine produces approximately 510,000 pounds of thrust. This is almost identical to the amount of thrust produced by the RS-25 engine...
The Raptor engine is a reusable methane-oxygen staged-combustion engine that powers the Starship system and has twice the thrust of the Falcon 9 Merlin engine.
For the first time, engineers at the company ignited a vacuum version of a Raptor rocket engine that had been attached to the Starship upper stage. The test-firing at sunset in South Texas...
It has 33 Raptor engines capable of producing 16.7 million pounds of thrust. Starship has six Raptors. Both Starship and Super Heavy will soft-land and be reused in future flights. In...
The Raptor 3 — the latest version — was a complete redesign of the engine to make it smaller, more streamlined, reliable, and most importantly, offering more thrust.
