SpaceX stacks, fuels and runs full wet dress rehearsal for Starship V3 Super Heavy as Booster 19 eyes a May test flight

SpaceX has stacked and fueled a new Starship V3 configuration for the first time, including a full wet dress rehearsal of Ship 39 and Booster 19 on Starbase’s Pad 2. Separate reporting says all 33 Super Heavy engines were fired on the pad, with an anticipated first V3 flight in mid-May (May 15 or as soon as May 19).

Briefing

What Hype is tracking

Starship V3’s pad readiness—stacking/fueling plus a full wet dress rehearsal clearing major pre-launch steps—offers the clearest near-term read on whether SpaceX’s incremental test cadence is holding after prior schedule slips, as flagged in SpaceX pushes next Starship test flight from April to May.
The emphasis on Pad 2 work for Booster 19 underscores that launch reliability is now gated as much by ground-system commissioning and leak/test readiness as by vehicle hardware, following earlier coverage of Pad 2 refinements ahead of Booster 19 return.
For industry planning, the reported milestone sequence (first-time stacking/fueling of V3 and engine firings—33 engines) signals how quickly SpaceX is integrating Starship/booster upgrades into test-flight objectives, building on earlier ground-testing progress for Starship Ship 39 advancing through preflight test work ahead of Flight 12.
