Super Heavy is the reusable first stage of the SpaceX Starship super heavy-lift launch vehicle, which it composes in combination with the Starship second stage. As a part of SpaceX's Mars colonization program, the booster evolved into its current design over a decade.[4][5][6] Production began in 2021, with the first flight being conducted on April 20, 2023, during the first orbital launch attempt of the Starship rocket.[7][8]
