The Space Bus was a space transport produced both the Earth Federation and the Principality of Zeon.
The Earth Federation and the Principality of Zeon used the space bus to transport personnel in space.
The Space Bus was designed for transporting people across short distances, usually between locations within a colony or military base or between places in neighbouring colonies or space outposts. While the designs of the space bus produced Earth Federation and Principality of Zeon differ cosmetically, they are almost identical in terms of form and function.
