Important to note that the induced mass (mass required by a given engine design that is not the engine itself) of Raptor 3, while far better than Raptor 2, still has a lot of room for improvement.

Thrust will exceed 300 tons with Raptor 3.x (thrust/mass>200), enabling 10,000 tons of thrust at liftoff and there might be up to 5 sec of Isp gain over time.

Getting close to the limit of known physics.

In a few years, we will finally have a Raptor 3/4 vacuum version (giant nozzle) that has an Isp of 380

The work this group is pumping out is insane. Just the part deletion progression is impressive but the thrust, bar, and isp gains in the process are amazing.

Performance stats of previous versions:

Raptor 1 (sea level variant)

Thrust: 185tf

Specific impulse: 350s

Engine mass: 2080kg

Engine + vehicle-side commodities and hardware mass: 3630kg

Raptor 2 (sea level variant)

Thrust: 230tf

Specific impulse: 347s

Engine mass: 1630kg

Engine + vehicle-side commodities and hardware mass: 2875kg

Raptor 3 is designed for rapid reuse, eliminating the need for engine heatshields while continuing to increase performance and manufacturability
