IFT-12 Slides to Late May 2026 — OLP-2 Deluge Repair Expected 2–3 Weeks; Booster 19 / Ship 39 Block 3 Stack Waits on Pad

Analysis published May 7, 2026 confirmed that Starship's 12th Integrated Flight Test (IFT-12) will not launch before late May 2026, as SpaceX engineers work to repair and re-qualify the water deluge system at Orbital Launch Pad 2 (OLP-2) following the May 5–6 gas generator explosion. Repair estimates place the earliest pad-ready date in the May 27–31 window, with early June emerging as the most probable backup. The Booster 19 / Ship 39 Block 3 / V3 vehicle stack remains vertical on OLP-2 and is unaffected by the deluge incident — SpaceX confirmed no damage to the launch vehicle itself. The Block 3 / V3 configuration features Raptor 3 V3 engines, a total vehicle height of 124.4 m (408 ft, approximately 1.2 m taller than the V2), enhanced propellant mass fractions, and a design target of more than 100 metric tons to LEO in a fully reusable configuration — nearly three times the demonstrated V2 capacity. IFT-12 marks the first Starship launch from OLP-2 and will fly a suborbital arc, with both Booster 19 and Ship 39 targeting ocean splashdowns to validate the Block 3 architecture before attempting catch operations. This is the third IFT-12 delay following the April FAA mishap investigation and Starbase RUD. The slip adds urgency: SpaceX's public S-1 IPO registration statement is expected around May 15–22, meaning prospective investors may receive the prospectus before seeing IFT-12's outcome. Analysts flagged that any Block 3 anomaly during the pre-IPO period could affect investor sentiment at SpaceX's targeted $1.75 trillion Nasdaq valuation.
