SpaceX is pushing two huge Starship production buildings forward at once, and the one at Starbase already rises above the company’s existing Megabay halls. New images show the Texas Gigabay climbing to a seventh level, while the Florida site at Roberts Road is moving toward roof and floor completion. The buildout points to a bigger question: how much Starship production can SpaceX sustain as it expands capacity in Texas and Florida?
The timing is awkward for anyone trying to keep up with SpaceX’s pace. The company is still treating Starship as a development program, but it is also building industrial capacity that looks more like a factory network than a single launch site. That is the real tell here: SpaceX is betting on volume, not just splashy test flights.
Starbase Gigabay rises above the Megabay pair
At Starbase in Texas, the Gigabay frame has now reached the seventh level and is visibly taller than Megabay 1 and Megabay 2, the current assembly halls used for Starship and Super Heavy work. Those existing buildings stand at about 100 meters, which gives a sense of just how absurdly large the new structure is becoming. Construction equipment and cranes are still active around the shell, so this is not just a vanity project with a dramatic name.
Roberts Road Gigabay nears completion
Florida’s Roberts Road site is advancing too, with the main structure close to completion and roof and floor elements going in. SpaceX has not hidden the ambition: Elon Musk has said the building will be among the largest in the world and is intended to support production of a thousand Starship spacecraft a year. That number is the kind of target that makes aerospace engineers reach for coffee and accountants reach for the exit.
A factory built for a higher Starship tempo
The scale of the buildings says as much about SpaceX’s plans as any official slide deck. In 2025, the exact number of Starships assembled was not disclosed, but the company did carry out five test launches of the Starship system, pairing Super Heavy with the Starship upper stage. That makes the industrial buildout look less like excess and more like preparation for a much higher launch and production rate.
- Starbase Gigabay: up to the seventh level and taller than Megabay
- Megabay 1 and Megabay 2: about 100 meters tall
- Roberts Road Gigabay: main structure close to completion
- Stated target: 1,000 Starship spacecraft per year
The open question is whether SpaceX can turn these giant shells into a truly industrial Starship line without tripping over the same technical bottlenecks that have slowed the program before. The buildings are going up fast. The harder part will be making the rockets do the same.
