The Raptor 2 had a 230tf thrust, a 347s specific impulse, and a 1630kg engine mass. The new Raptor 3 has a 280tf thrust, a 350s specific impulse, and an engine mass of 1525kg.

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 ...

The Raptor 2 had a 230tf thrust, a 347s specific impulse, and a 1630kg engine mass. The new Raptor 3 has a 280tf thrust, a 350s specific impulse, and an engine mass of 1525kg.

The vacuum version of the Raptor will produce 3.5MN of thrust, with a specific impulse of 382 seconds, thanks to its 200 expansion ratio nozzle. It will have an estimated diameter of four meters.

Efficiency is everything in rocketry, which is why specific impulse (Isp) is such a big deal in this field. Simply put, this number represents the amount of thrust an engine can generate when ...

SpaceX test-fired Feb. 3 the first flight version of the Raptor engine the company has developed for its next-generation launch system.

SpaceX continues with the Starship pace, with another busy week involving the reveal and first firing of the Raptor 3 engine, a spin prime — and not a static fire — for Ship 30, tons more ...

Raptor 3 also promises higher Isp (i.e. specific impulse, a measure of how efficiently a rocket engine uses its fuel), more thrust, “and many other improvements,” Musk said.
