SpaceX is gearing up for Flight 12, which will mark the first launch of Starship Version 3 (V3) hardware. Flight 11, scheduled for late 2025, is expected to be the final mission using the V2 architecture. Flight 12 is targeted for the first quarter of 2026 and will feature Ship 39, the first upper-stage V3 prototype, along with Booster 19.
As of late December 2025, Ship 39 is in an advanced stage of preparation at the Mega Bay and is expected to move soon to Massey’s test site for structural and cryogenic testing. Booster 19 is being stacked and is on track for completion by the end of December.
Starship V3 introduces significant upgrades over the previous version:
- Raptor 3 Engines: Simplified design with internal cooling channels, eliminating external plumbing and heat shielding.
- Increased Size and Thrust: Taller and more powerful booster, capable of producing up to 10,000 metric tons of thrust, nearly three times that of Saturn V.
- Improved Aerodynamics: Asymmetrical chine layout and three grid fins enhance gliding performance and control during return to the launch tower.
- Integrated Hot Staging: Hot staging structure is built directly into the booster, reducing turnaround time compared to older versions that used a separate ring.
SpaceX is also preparing Orbital Launch Pad 2 (Pad B) at Starbase to accommodate V3 flights. The pad features a reinforced tower and shorter “chopstick” arms specifically designed to catch the larger, heavier vehicles.
The upgrades are designed to support higher performance, rapid mass production, and operational efficiency for the next generation of Starship launches.
