Starbase OLP-2 Water Deluge System Explodes During Pre-IFT-12 Test — Methalox Gas Generator Ejected; IFT-12 Mid-May Window in Doubt

A dramatic explosion struck SpaceX's Orbital Launch Pad 2 (OLP-2) at Starbase, Texas on May 5–6, 2026 during a high-volume water deluge system test conducted ahead of Starship's 12th Integrated Flight Test (IFT-12). The deluge system — designed to spray 350,000 gallons of water during Starship ignition to suppress acoustic energy and protect the pad structure — uses a methalox gas generator to supply high-pressure nitrogen that drives the water flow. During the test, this gas generator exploded violently, ejecting the combustor unit and multiple roof panels from the surrounding structure. Videos shared widely on social media showed enormous water columns shooting hundreds of feet upward above the pad, followed by visible debris being hurled into the surrounding area. SpaceX engineers assessed the explosion as isolated to the gas generator assembly; the OLP-2 catch tower, Mechazilla arms, flame trench, and the Block 3 Starship vehicle stack (Booster 19 / Ship 39) mounted on the pad were evaluated as unaffected. However, the deluge system requires full repair, component replacement, and re-qualification testing before IFT-12 can proceed — raising the probability that both the May 12 (first opportunity) and May 15 (backup) windows would be missed. The incident is the third delay for IFT-12, which had already been postponed from April 2026 due to an FAA mishap investigation following an anomaly around April 2 and a Rapid Unscheduled Disassembly (RUD) at Starbase on April 6. IFT-12 is to be the first flight of SpaceX's Starship Block 3 / V3 configuration — featuring Raptor 3 V3 engines, 124.4 m overall height, and a 100+ ton payload capacity to LEO — and the maiden launch from OLP-2.
