SpaceX Booster 19 Prelaunch Testing Begins as Starship V3 Program Moves Forward
SpaceX Booster 19 prelaunch testing is underway as SpaceX prepares its next Block 3 Super Heavy booster for a potential flight in early to mid-March 2026. Booster 19 will support the debut of the Starship Version 3 architecture, featuring new Raptor 3 engines and design improvements. Prelaunch testing — including cryogenic measurements and static firings — is crucial for validating performance ahead of a major test flight, likely part of the Starship Flight 12 campaign.
