Mega Bay 1

Mega Bay 1 (MB1) at Starbase serves as the current location for Super Heavy Booster assembly including stacking operations and engine installation.

It features a larger base area than High Bay and is slightly taller allowing for easier access to work on vehicles and the capability to relocate boosters without the need to displace other boosters. There is also office space at the top of Mega Bay 1.

Mega Bay 1 features a turntable in the front corner, which is used to stack vehicles by rotating the stack along a robotic welder inside the bay. Then, on the back side of the bay, there are work platforms that allow
for engine installation and other work. Booster 13 (B13) is currently located on the turntable; Booster 11 (B11) and Booster 10 (B10) are currently located on one of the back work platforms.

## History

Originally, prior to a tweet by Elon Musk referring to this facility as Mega Bay, the community used to refer to it as "Wide Bay". However, it is worth also noting that official documents from the FCC designate this facility as High Bay 2. The difference between Elon Musk's chosen name and the FCC documents created a discrepancy in the nomenclature, leading to some disagreement regarding the facility's proper name but generally Mega Bay was the accepted name at this time.

However as the construction of a second facility of similar size to Mega Bay commenced, a shift in naming occurred. The facility that was initially referred to as Mega Bay became known as Mega Bay 1, while the ly constructed facility was designated as Mega Bay 2 by the community but many people still refer to the first Mega Bay as just simply Mega Bay. There is no definite right or wrong name.
