FULL STORY ======================================================================

Following Booster 19s successful full-duration, full-thrust 33-engine static fire on May 7, 2026, its partner Ship 39 is set to roll out to join the booster and form the Flight 12 stack ahead of this weekends Wet Dress Rehearsal. Since Booster 19 rolled out of Mega Bay 1, several visual and structural differences have been noted compared to its previous appearances.

The aft section now features a full factory paint application matching official renders, providing improved thermal protection and a cleaner aesthetic.

Additional protective covers have been installed over the autogenous pressurization lines, extra stringers reinforce the forward section facing
the tower, and the hot-stage truss box covers have received a fresh black paint job, likely for better durability and heat management.



Prior to the May 7 test, Booster 19 had already completed an extensive series of ground tests: four cryogenic proof tests, three pneumatic pressure tests, three tanking operations, two spin primes, two static fires (one 10-engine
and one 33-engine), and a booster-only Wet Dress Rehearsal (WDR).

While it has not surpassed the test count of veteran Booster 7, this rigorous campaign underscores SpaceXs commitment to thoroughly validating the new
Block 3 hardware and Pad 2 infrastructure ahead of its debut flight.

The static fire itself lasted approximately 1415 seconds, with all 33 Raptor
3 engines igniting and operating at full thrust. SpaceX described the test as a full duration and full thrust 33-engine static fire with Super Heavy V3. Full duration and full thrust 33-engine static fire with Super Heavy V3 pic.twitter.com/vUJTqoHEZy

Earlier attempts during the week were scrubbed due to water deluge pressure
or sensor issues, but the team quickly recycled and achieved a successful firing highlighting the capabilities of the new deluge and flame trench system at Pad 2.

Unlike previous Super Heavy static fires on Pad 1, which were typically limited to around 50% throttle to protect ground infrastructure, this test
ran at liftoff power levels. The upgraded deluge system at OLP-2 proved its worth, successfully managing the immense energy release from the higher-performance Raptor 3 engines.

Block 3 boosters introduce several key advancements, including a taller structure for increased propellant capacity, an integrated hot-staging ring, three larger grid fins for improved control during recovery, and the switch
to Raptor 3 engines that allow for reduced engine shielding. These changes
are designed to enhance overall vehicle performance, reliability, and reusability as SpaceX works toward rapid turnaround operations.

With the static fire complete, focus has shifted to stacking Ship 39 for integrated testing. However, a setback occurred when part of the chopsticks
on Pad 2s tower sustained damage, possibly from the vibrations and pressures of the static fire. Crews removed a damaged skate on the center line of the carriage overnight on May 7, but it was replaced late Friday, clearing the
way for stacking.

With Booster 19 and Ship 39 about to be mated, the first full-stack Wet Dress Rehearsal at Pad 2 is expected to take place over the weekend.



This critical test will simulate a complete countdown sequence, including clearing the range, evacuating the village, and fully loading both vehicles with propellant. It will provide the launch control team with invaluable real-world experience on the new pads systems and procedures, helping
identify any issues before the actual launch attempt.

Following the WDR, both vehicles are slated to return to the production area for final inspections, payload integration (if applicable), and any necessary refinements. They will then roll out for the terminal countdown and Starships 12th integrated flight test, currently targeting mid-May. The mission is expected to follow a suborbital profile with planned ocean splashdowns for both stages.

Details on Ship 39s configuration remain limited while it awaits transport, but early imagery shows metallic tiles installed in select areas of the heat shield positioned near the edges rather than centrally, as was the case on Ship 37 during Flight 10.

Those earlier tiles experienced melting and oxidation in reentry plasma, spraying rust-like debris across the vehicle. The new positioning on Ship 39 may yield better results, though heat shield performance remains a key area
of iteration.

While full mission success would be a major milestone for SpaceX, this
remains a test flight featuring the debut of the Block 3 vehicle, its Raptor
3 engines, and operations from the new Pad 2. Should the mission go largely according to plan, the turnaround to the next flight could be short, with Booster 20 already stacked and Ship 40 having completed cryoproofing.
