๐ UPDATE โ May 9, 2026
SpaceX has achieved a major milestone: the first full stack of Starship V3 was completed today at Starbase, confirmed directly by SpaceX via their official account. This marks the debut of the next-generation Starship design stacked for the first time, representing a significant step beyond the Block 3 vehicle currently targeting Flight 12. The stacking event was captured in stunning imagery shared by SpaceX and independent observers including Joe Tegtmeyer and NASASpaceflight, who noted even the legacy Booster 18 test stand appeared to be "watching" the historic moment. While Flight 12 and 13 preparations continue on the current hardware, the V3 full stack signals SpaceX is already advancing its longer-term Starship roadmap in parallel.

๐ UPDATE โ May 9, 2026
SpaceX has officially stacked Starship and Super Heavy V3 together on the Starbase launch pad for the first time, a major milestone signaling that Flight 12 preparations are advancing rapidly. The stacking marks the debut of the Block 3 vehicle in its fully integrated configuration at Pad 2, bringing the mid-May launch target closer to reality. SpaceX confirmed the milestone via their official X account on May 9, sharing multiple photos of the stacked vehicle.

๐ UPDATE โ May 9, 2026
Starship has officially become the tallest rocket in history, surpassing its previous iteration by approximately 1.3 meters (~5 feet). A Wet Dress Rehearsal (WDR) is underway today at Starbase, and if it goes smoothly, SpaceX is targeting no earlier than May 15 for the Flight 12 launch window โ potentially less than a week away. The milestone was highlighted by aerospace photographer Joe Tegtmeyer, citing a photo by @EzekielOverstr1.

"Awesome shot by @EzekielOverstr1 of the newly crowned tallest rocket in history โฆ beating the previous Starship by about 5 feet or ~1.3 meters! WDR later today and if all goes well, perhaps Flight 112 launch in less than a week (currently NET 15 May)!"
๐ UPDATE โ May 9, 2026
Ship 39 has entered Highway 4 at Starbase and is now en route to Pad 2, where it will be stacked with Booster 19 ahead of Starship Flight 12. This rollout marks a concrete step forward in integrated vehicle assembly, bringing the Block 3 debut closer to reality. NASASpaceflight confirmed the movement early on May 9 UTC, signaling that stacking operations could be imminent in the coming days.

๐ UPDATE โ May 9, 2026
While Flight 12 preparations continue, SpaceX has rolled out and stacked the first Starship V3 vehicle at Starbase โ a significant milestone representing a new design iteration beyond the Block 3 hardware currently targeting mid-May's launch. The V3 designation suggests meaningful upgrades over the Block 3 configuration, though SpaceX has not yet detailed the specific changes. This rapid hardware progression highlights SpaceX's accelerating cadence, with V3 stacking already underway even before Block 3 has flown. NASASpaceflight first reported the rollout on May 9, 2026.
๐ V3 design changes vs. Block 3 remain undocumented by SpaceX at time of publication.
๐ UPDATE โ May 7, 2026
Elon Musk has officially confirmed a Starship static fire test was conducted, posting a fiery triple-flame emoji announcement on X alongside video footage of the test. This marks a significant pre-flight milestone for the upcoming Starship launch campaign, bringing Flight 12's Block 3 debut from Pad 2 one critical step closer. A successful static fire clears the way for SpaceX to finalize its launch readiness review and submit for FAA launch approval.
๐ UPDATE โ May 7, 2026
SpaceX has successfully completed a pre-launch static fire test of Booster 19 at Pad 2, marking a significant milestone toward the first flight of the Block 3 Starship. With the static fire now in the books, SpaceX is closing in on full stack operations โ where Ship and Booster are mated together on the launch mount โ ahead of Flight 12's targeted mid-May liftoff. This clears one of the final major checkboxes before the debut of the new Block 3 variant.
@NASASpaceflight ยท May 7, 2026"SpaceX is closing in on the first flight of the Block 3 Starship, completing a pre-launch Static Fire test of Booster 19 at Pad 2 ahead of full stack operations."
SpaceX's Starship program is accelerating on two fronts simultaneously. Flight 12 โ the maiden launch of the Block 3 Starship configuration โ is now targeting mid-May 2026 from Orbital Launch Pad 2 at Starbase, while Ship 40 has already begun testing in preparation for Flight 13. The pace of vehicle turnover signals a cadence unlike anything the program has managed before.
What Flight 12 Actually Represents
This isn't just another test flight. Flight 12 marks the first launch of the Block 3 (V3) Starship โ a substantially redesigned vehicle that SpaceX considers a generational leap over its predecessors. According to reporting from NASASpaceflight and space.com, the integrated stack of Booster 19 and Ship 39 stands 408.1 feet (124.4 meters) tall, making it the largest rocket ever prepared for flight.
The V3 configuration brings several meaningful changes. Booster 19 is powered by Raptor 3 engines and features an integrated interstage along with three grid fins โ down from the four used on previous boosters. Ship 39 incorporates docking ports designed for on-orbit propellant transfer, a capability that's central to NASA's Artemis lunar architecture. Perhaps most significantly, the V3 is targeting a payload capacity exceeding 100 metric tons to Low Earth Orbit โ nearly three times the 35-ton capacity of the V2.
Both vehicles have cleared major testing milestones. Booster 19 completed its first full 33-engine static fire on April 15, and Ship 39 ran a full-duration static fire the day before. The FAA has granted flight-safety approval, and the FCC communications license is valid through October 2026. The regulatory path is clear.
Pad 2's First Launch
Flight 12 will also be the inaugural launch from Orbital Launch Pad 2 (OLP-2) โ a second launch complex SpaceX has been constructing at Starbase to increase launch cadence. Pad 2 is currently undergoing full stack testing with the Flight 12 vehicles, a standard pre-launch checkout process. The addition of a second pad is a structural shift for the program: it means SpaceX can theoretically prepare one vehicle for flight while another is being stacked or serviced, removing a critical bottleneck.
Elon Musk indicated in early April that the next Starship flight was four to six weeks out, a timeline that aligns squarely with the mid-May window now being reported. A specific target of May 12 has been identified by tracking sources, though SpaceX has not officially confirmed a date.
Flight 13 Is Already in Motion
The detail that stands out most in today's update is Ship 40 beginning testing for Flight 13 before Flight 12 has even launched. Ship 40 and Booster 20 are assigned to the second V3 flight, meaning SpaceX is building a pipeline rather than preparing vehicles sequentially. If Flight 12 proceeds on schedule and Flight 13 hardware continues through its test campaign without major issues, the gap between consecutive Starship flights could compress significantly compared to the months-long intervals seen in earlier flights.
That cadence matters beyond the program itself. Rapid reuse and fast turnaround are prerequisites for Starship's commercial and NASA missions โ and the overlap of Flight 12 final preparations with Flight 13 early testing suggests SpaceX is treating that goal as operational reality, not future aspiration.
