The command/control module was the primary processing unit of a drone barge. It was preprogrammed with all liftoff, flight, and landing data to control the unmanned barge, including hyperspace travel. On their mission to Orron III in 2 BBY, the Millennium Falcon and her crew took the place of the module in a hijacked barge shell. The freighter's computers handled the command/control module duties.
