IT Home reported on August 3 that Musk posted a photo today showing a Raptor 3 numbered SN1, which is also SpaceX's first Raptor 3 engine, suggesting that this upgraded Raptor engine has entered the mass production stage.

As shown in the figure, the structure of Raptor 3 has been greatly simplified compared with the previous two generations, and the overall structure is more compact. A large number of pipelines that were previously exposed to the outside have been integrated together. Musk said that Raptor 3 does not need any heat shield, which also avoids the quality and complexity problems brought by the heat shield, as well as the need for a fire extinguishing system. It is also lighter, more powerful, and more efficient than Raptor 2.

According to official SpaceX data, the Raptor 3 engine has a sea level thrust of 280 tons (IT Home Note: the current generation is 230 tons). When combined with the 35 engines of the next-generation super-heavy booster, its takeoff thrust can reach 9,800 tons, which is about 30% higher than the current model.
