SpaceX is already well underway with testing of its first majorly-upgraded version of Starship, known as Starship SN15.
The company elected to forego SN12-SN14 after successful testing of SN7.2, a test tank made from the new and lighter steel that Starships will be made from starting with SN15 onward.
The remains of SN11, which exploded midair after a major anomaly caused a hard start on the landing burn, were still being cleaned from the surrounding Boca Chica, Texas, area while SN15 quickly finished stacking in the High Bay and was rolled to suborbital Pad A on April 8, 2021.
