Starship SN8 was a test vehicle designed to perform a 12.5 km test flight. It became the first Starship to be outfitted with three Raptors (SN30, SN32, and SN39). After the first static fire, SN39 was replaced by SN36. After the third static fire, Raptor SN32 was removed due to an anomaly and replaced by Raptor SN42. Thus, SN30, SN36, and SN42 are the Raptors that performed the eventual test flight. During the flight, Starship SN8 was lost due to an anomaly with header tank pressure but completed many test objectives.
