GoKawiilSpaceX Starship stands 407 feet tall with record 18.1 million pounds of thrust
SpaceX's fully stacked Starship launch vehicle measures 407 feet, combining the 236.2-foot Super Heavy booster and the 170.6-foot Starship spacecraft. It is currently the tallest and most powerful rocket ever flown, generating 18.1 million pounds-force of liftoff thrust, up from the 16.7 million pounds-force recorded during its first full-stack launch in April 2023, when booster exhaust damaged the launch pad and scattered debris across 385 acres.
