SpaceX has unveiled the Raptor 3 engine, marking vital developments in thrust, particular impulse, and mass effectivity in comparison with earlier variations. The Raptor 3 boasts a thrust of 280 tf, a particular impulse of 350s, and an engine mass of 1525 kg. The SpaceX Raptor 3 engine has potential to exceed 300 tons of thrust in future iterations, emphasizing ongoing efforts to enhance effectivity.
Raptor 3 is 36% lighter than Raptor 1. It has 51% extra thrust at sea degree versus raptor 1.
Raptor 3 is 7% lighter than Raptor 2. It has 21% extra thrust at sea degree versus raptor 2.
Elon Musk signifies that Raptor might get one other 8-10% extra thrust.
Raptor 3 has 2.75 million newtons of thrust versus 2.26 million newtons for the Raptor 2.
33 Raptor 3 engines would supply 90.75 million newtons of thrust for a 33 engine tremendous heavy booster.
35 Raptor 3 engines would supply 96.3 million newtons of thrust for a 35 engine tremendous heavy booster.
The Saturn V had 34.5 million newtons of thrust.
If Raptor 3 is improved to over 300 tons of thrust at sea degree then every engine would have 2.95 million newtons of thrust. 35 Raptor 3.X engines would provid e103.25 million newtons of thrust for a 35 engine tremendous heavy booster.

I had an older estimate of the Raptor 3 engine primarily based upon earlier slides from SpaceX.
