It’s hard to imagine the amount of thrust needed to launch a space shuttle into orbit, let alone one as massive as SpaceX’s Starship. However, the company’s Raptor engines do just the trick, even if they need nearly 40 of them to complete the spacecraft’s journey. So, how powerful are they?
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 Starship (plus the booster) off the ground and into space. For comparison, the GEnx-2B Engine that powers a Boeing 747-8 creates 66,500 lb of thrust compared to the 507,063 pound-force from each Raptor engine.
However, the SpaceX propulsion team didn’t stop there. In May 2023, Elon Musk tweeted that the SpaceX engineers achieved even more thrust with the Raptor V3. The newest version of the space rocket achieved 269 tons of thrust, putting the Super Heavy Booster’s total thrust at 8,877 tons or 19.5 million pounds.
On the other hand, the Raptor Vacuum engines boast a larger exhaust and expansion nozzle, which increases their efficiency and possesses more thrust than the standard Raptors (especially in space). The engines output 258 tf, giving Starship 774 tons of force (from just three RVacs) after separation in space.
