Raptor 3 is one of the clearest examples of how fast SpaceX engineering evolves

When SpaceX first revealed it, the engine looked so ridiculously stripped down that even ULA CEO Tory Bruno thought SpaceX was showing a partially assembled engine

SpaceX had eliminated and integrated so much external plumbing and complexity that Raptor 3 basically became the perfect embodiment of Elon Musk’s engineering philosophy:
“The best part is no part”

Cleaner, simpler, more integrated, and more powerful

And then SpaceX puts 33 of them underneath Super Heavy. One Raptor 3 is already an insane piece of engineering

33 firing together is what makes Starship unlike anything humanity has ever built before
