Autobot Orbital Command Hub
From Transformers Wiki
The Autobot Orbital Command Hub is the central base of Autobot operations in their galactic war against the Decepticons. A massive space station, it orbits the planet Opulus.[1]
It is on the Hub that Autobots unassigned to warfront planets are stationed, waiting on-hand in the event that they'll be needed. From these Autobots a crew can be assembled quickly to man one of the Arks.
Due to the pan-galactic nature of the war, the Autobots also use regional command hubs. Spotlight: Cyclonus
