SpaceX has test-fired the engines on its newest and largest Starship rocket at the company’s Boca Chica launch site in South Texas, clearing one of the final hardware milestones before an expected mid-May launch attempt. The vehicle, widely reported to be the first Version 3 Starship, stands roughly 408 feet tall when fully stacked and is believed to fly exclusively on Raptor 3 engines, a propulsion upgrade that has never left the ground. If those figures hold, Flight 12 would send the tallest and most powerful rocket ever built on its next step toward making Starship an operational launch system.
The regulatory path is opening
The clearest sign that Flight 12 is close comes from the federal agencies whose paperwork must be finished before any Starship can leave the pad. The U.S. Department of Transportation and the FAA recently published a final Tiered Environmental Assessment along with a Finding of No Significant Impact covering expanded airspace closures, new launch trajectories, and Starship landings at Boca Chica. That determination removes an environmental review bottleneck that delayed earlier flights by months.
Environmental clearance, however, is only one layer. According to the FAA’s own Starship licensing FAQ, SpaceX must also hold a valid vehicle operator license, close out any open mishap investigations from prior flights, and receive mission-specific authorization before launch. The agency has not yet posted a public statement confirming that all of those boxes have been checked for Flight 12, so the final regulatory green light remains pending.
On the ground, the City of Starbase has begun posting road and beach closure notices tied to spaceflight operations. The closures cover Boca Chica Beach and State Highway 4, citing hazard zones and clear-zone requirements that apply during propellant loading, static fires, and launch attempts. These postings typically tighten in the days before a major event, and their appearance now suggests SpaceX’s ground campaign is well advanced.
What makes Version 3 different
SpaceX has not released an official spec sheet for the Version 3 Starship, so the details circulating online come from secondary reporting and the spaceflight community rather than company filings. With that caveat, the picture that has emerged is striking.
The reported 408-foot stack would make this Starship taller than the Saturn V (363 feet) that carried Apollo astronauts to the Moon and considerably taller than NASA’s Space Launch System (322 feet). The height gain is attributed to a stretched upper stage designed to carry more propellant and, eventually, heavier payloads.
The bigger engineering story may be the engines. Previous Starship flights used a mix of Raptor 2 engines on the Super Heavy booster and the Ship upper stage. Version 3 is reported to fly with Raptor 3 engines throughout, an upgrade SpaceX has said delivers higher thrust and improved reliability from a simpler, lighter design. Running an all-Raptor-3 configuration for the first time on a vehicle this large would represent a significant leap in propulsion validation.
Static fire and what comes next
The recent static fire, during which the booster’s engines were briefly ignited while the vehicle remained clamped to the launch mount, is a standard pre-flight checkout that verifies engine ignition sequencing, thrust levels, and pad systems. Community observers near the site described the test as nominal, though SpaceX has not released performance data, burn duration, or details on any anomalies. In past campaigns, even clean-looking static fires have occasionally led to additional inspections or hardware swaps that pushed timelines back by days or weeks.
Assuming no issues surface in post-fire reviews, the remaining gates are primarily regulatory and meteorological. The FAA’s mission-specific authorization is the single biggest variable. Weather along the Gulf Coast in mid-May can shift quickly, with coastal storms, wind shear, and thick cloud layers all capable of scrubbing a launch window even when the rocket is ready.
Building on Flight 11
Flight 12 would continue a rapid test campaign that has accelerated over the past year. SpaceX has used each successive flight to push Starship’s envelope: early missions focused on stage separation and controlled reentry, while more recent attempts have included catching the Super Heavy booster with the launch tower’s mechanical arms. Each flight has fed data back into hardware and software changes for the next.
The jump to a Version 3 vehicle with an all-new engine configuration raises the stakes. A successful flight would validate the Raptor 3 engine at full scale, demonstrate the structural changes in the stretched airframe, and move SpaceX closer to the performance targets it needs for NASA’s Artemis lunar lander contract and its own ambitions for Mars-class missions.
Tracking the mid-May 2026 launch window from Cameron County
SpaceX has not announced a firm launch date. The road and beach closure windows posted by Starbase suggest the company is targeting the middle of May 2026, but those windows include alternate days to accommodate slips. SpaceX typically confirms a launch attempt on its social media channels and streams the event live on X (formerly Twitter) and its website.
For anyone planning to watch from Cameron County, the closure notices are the best real-time indicator of when activity is imminent. Until the FAA issues its formal authorization and SpaceX calls a launch attempt, mid-May remains a working target, not a fixed date. The hardware appears ready. The paperwork is catching up. What happens next depends on whether the last few regulatory and weather dominoes fall in time.
