SpaceX Starship V3 Super Heavy booster B18 explodes during pressure test at Starbase, delaying upgrade timeline

During a Nov. 21, 2025 pressure proof test at Starbase, SpaceX’s first Version 3 Super Heavy booster (B18) suffered a visible detonation; there were no injuries. The anomaly will delay rollout of Starship v3 upgrades and compress the program’s planned launch cadence and testing schedule.

Briefing

What Hype is tracking

  • The failure occurred during a ground pressure test on Nov. 21 and will slow the rollout of critical Starship V3 hardware, threatening the upgrade and test cadence enabled by an FAA clearance for 25 Starship launches in 2025 (see FAA clearance for 25 Starship launches in 2025: https://hype.aero/?story=4a7ae853-7749-4c34-8fb4-8e15dd4e4ece).
  • The anomaly strikes as SpaceX is reconfiguring Starbase infrastructure — including demolition and realignment at Pad 1 to support next‑generation Starship work — which could extend pad activation and integration timelines (see Starbase Pad 1 demolition and reconfiguration: https://hype.aero/?story=fa7b91a0-bbb7-4c09-8dac-e9ea81ba6611 and ramp demolition and realignment at Starbase: https://hype.aero/?story=43e840d6-2622-44a1-934c-2bc622abfa91).
  • Any delay to V3 development affects program-level objectives tied to lunar and crewed architectures — including SpaceX’s revised Starship HLS concept and plans to accelerate Artemis-related timelines (see SpaceX’s simplified Starship HLS proposal: https://hype.aero/?story=c22b4a6c-65e6-4ddc-86ce-99710f7aad6e) and shifts in company resources that already risk Falcon 9 cadence (see Falcon 9 cadence risk as Starship work scales: https://hype.aero/?story=8ab941fa-e020-47ff-bef2-c74249e14864).
