SpaceX is targeting May 15, 2026, for the maiden flight of its Starship Version 3, the largest and most powerful rocket ever built. Designated Flight 12, the mission would launch from the company’s Starbase facility in Boca Chica, Texas, sending a 408-foot vehicle into the sky on the thrust of 33 next-generation Raptor 3 engines. If the rocket performs as designed, it will be capable of lofting roughly 100 metric tons to low-Earth orbit, nearly doubling the capacity of earlier Starship versions and eclipsing every operational launch vehicle on the planet.
Federal Aviation Administration operational planning records already reserve airspace for the attempt. But with less than a week until the window opens, key regulatory and technical milestones still need to fall into place.
FAA documents pin down the launch window
The clearest evidence for the May 15 date comes from the FAA’s Air Traffic Control System Command Center (ATCSCC). A daily operations plan dated May 7, 2026, lists a window for “SPACEX STARSHIP FLT 12” at “STARBASE TX” running from 2230Z on May 15 to 0033Z on May 16. That translates to roughly 5:30 p.m. to 7:33 p.m. Central Daylight Time, with a backup window covering the same block on May 16.
A second ATCSCC record, the Previous Operations Plan Advisory, independently confirms the identical primary and backup windows. Two distinct FAA operational documents pointing to the same dates and times lend the target considerably more weight than a single scheduling entry. Both originate from the division responsible for integrating launch and reentry operations into national airspace.
The FAA also maintains a stakeholder engagement page for the Starship-Super Heavy program at Boca Chica. That hub aggregates environmental assessments, airspace closure documentation, and license-related materials, providing the regulatory backdrop for every Starship flight reviewed at the South Texas site.
One important detail: SpaceX’s current Starship launch license, VOL 23-129, requires a separate modification for each flight beyond the original authorization. That process involves safety reviews, environmental checks, and coordination across federal agencies. The fact that ATCSCC planners have already slotted Flight 12 into their schedules suggests the modification process is either complete or advanced enough for air traffic managers to build around it.
What makes V3 different from earlier Starships
Starship V3 represents the most significant redesign since the vehicle began flying. According to specifications SpaceX has shared publicly, including updates from CEO Elon Musk and the company’s website, the V3 upper stage features stretched propellant tanks that hold substantially more liquid methane and liquid oxygen than the V2 ship. That extra propellant, combined with the higher efficiency of the Raptor 3 engine, is what pushes the payload capacity toward the 100-metric-ton mark.
The Raptor 3 is a meaningful leap from its predecessor. SpaceX has described it as a simplified, higher-thrust engine with fewer parts and a more integrated design that eliminates much of the external plumbing visible on Raptor 2. The company says each Raptor 3 produces greater thrust while being lighter and cheaper to manufacture. Thirty-three of them power the Super Heavy booster; six more drive the upper-stage Starship ship.
At 408 feet tall when fully stacked, the V3 configuration stands taller than the Statue of Liberty and surpasses NASA’s Space Launch System (322 feet) and the legendary Saturn V (363 feet) that carried Apollo astronauts to the Moon. If the 100-ton payload figure holds, Starship V3 would offer more than four times the lift capacity of a Falcon Heavy and roughly twice what the SLS can deliver.
It is worth noting that these performance figures originate from SpaceX rather than from an independent regulatory filing. No FAA environmental impact statement or license modification document in the current public record specifies payload capacity or engine thrust numbers for Flight 12. The figures are widely cited across the aerospace industry but have not been independently verified through third-party testing data.
How SpaceX got here: the Flight 11 milestone
Flight 12 does not exist in a vacuum. SpaceX’s Starship test campaign has accelerated dramatically over the past year, with each mission building on lessons from the last. Flight 11, the most recent, achieved several firsts: the Super Heavy booster was caught by the launch tower’s mechanical arms (“chopsticks”) for a second time, and the upper-stage ship executed a controlled landing in the Indian Ocean, validating the heat shield and landing burn sequence that will eventually allow full reusability.
Those successes gave SpaceX the confidence to push forward with the V3 hardware rather than continuing to iterate on the V2 design. The jump from V2 to V3 is roughly analogous to moving from a prototype to a production-intent vehicle: the bones are similar, but nearly every major subsystem has been upgraded for higher performance and manufacturability.
What could still delay the launch
An ATCSCC airspace reservation is an operational coordination tool, not a launch authorization. SpaceX could scrub the attempt for technical reasons at any point, and the FAA could pull the window if late-stage safety reviews surface problems. The May 15 date should be treated as a working target, not a guarantee.
The license modification status for Flight 12 sits in a gray area. While VOL 23-129 established the framework for Starship launches, no specific modification number or approval date for this flight has appeared in publicly accessible filings. The ATCSCC scheduling entries imply coordination is underway, but the formal licensing chain from application to approval is not yet visible.
SpaceX also has not published a V3-specific environmental assessment through the FAA’s public filing system. Earlier Starship variants went through environmental reviews tied to the Boca Chica site, but whether those assessments cover the changes introduced in V3, particularly the larger propellant load and modified engine configuration, is unclear from the available record.
Weather is another variable. South Texas in mid-May can deliver clear skies or Gulf Coast thunderstorms with little warning, and upper-level winds must fall within acceptable limits for a vehicle this size.
Signals to watch before the May 15 window opens
Several signals will indicate whether Flight 12 is on track. Updated FAA notices, either reaffirming or revising the existing windows, will be the most reliable indicator. Activity at Starbase matters too: a static fire test of the fully stacked vehicle or a wet dress rehearsal (loading propellant without igniting engines) would suggest SpaceX is in the final stretch of launch preparations.
On the regulatory side, a formal license modification approval, if it becomes public, would confirm that the FAA’s safety and environmental reviews have concluded favorably. Any new environmental filings or incident reports, on the other hand, could point to unresolved questions that might push the schedule to the right.
For now, the evidence points to a real and active effort by SpaceX and federal regulators to put Starship V3 in the air by mid-May 2026. The airspace is reserved. The hardware appears ready or close to it. But spaceflight, especially with a vehicle flying for the first time, has a long history of humbling even the most aggressive timelines. The safest bet is to watch the FAA filings, keep an eye on Boca Chica, and be ready for the possibility that the first V3 launch slips past its current window.
