SpaceX Raptor 4 to hit 300 tons of sea-level thrust at same mass as Raptor 3

SpaceX has steadily raised Raptor sea-level thrust from 185 to a planned 300 metric tons while cutting engine mass, sharply improving thrust-to-weight. With 33 engines on Super Heavy, Raptor 4 would produce roughly 9,900 metric tons of liftoff thrust, nearly three times the Saturn V.
