Super Heavy Booster 19 hull shows test marks after static fire

Photos taken after SpaceX fired all 33 Raptor 3 engines show dark spots, smoke trails, some paint peeling and damage to protective tape, while the main structure appears intact.
Experts said the marks were exhaust and water residue from the sound suppression system, not structural damage. Raptor 3 engines use integrated cooling and need no external heat shielding.
SpaceX says the lighter, more efficient engines are cheaper to build and reusable. The upcoming 12th Starship flight is set to be the first major test of a Raptor 3-equipped vehicle.
Beyond successful tests, what flight hurdles must Raptor 3 clear to validate its revolutionary cost and reliability claims?
As NASA's moon missions approach, can SpaceX resolve Starship's critical safety flaws before astronauts must fly?
If Starship truly slashes launch costs, which Earth-based industries will be the first to be completely transformed?
Booster 19’s Full-Duration 33-Engine Static Fire Validates Block 3 Design Despite Hull Test Marks
Overview
In May 2026, SpaceX successfully completed a full-duration static fire test of Booster 19, the first Block 3 Super Heavy booster featuring advanced Raptor 3 engines and structural upgrades. This milestone followed earlier setbacks, including the destruction of the original Flight 12 booster in late 2025 and two aborted static fire attempts due to ground support issues. The rigorous testing campaign, including cryogenic proof tests, caused expected hull marks from thermal and pressure stresses, which engineers confirmed were within safe limits. To manage risks for the upcoming Flight Test 12, SpaceX plans an ocean splashdown instead of a booster catch, prioritizing data collection and safety as they advance toward operational Starship flights.
