The Gigabay will stand 380 feet tall and provide approximately 46.5 million cubic feet of interior processing space, with 815,000 square feet of workspace. It is engineered to support Starship and Super Heavy vehicles up to 81 meters (266 feet) tall and will feature 24-30 work cells for integration and refurbishment, equipped with cranes capable of lifting up to 400 US tons.
Compared to the existing Megabay facilities at Starbase (Mega Bay 1 and Mega Bay 2), the Gigabay offers over 11 times the square footage and 19 additional work cells.

Construction of the Starfactory began around February 2022, with multiple phases completed or underway by 2025. The facility, spanning approximately 1 million square feet across its phases, is designed to streamline manufacturing processes, with the long-term goal of producing one Starship per day (approximately 365 Ships per year).
