The barges use anti-gravity generators for lift. They are used in major cities such as High Charity, and are normally used to transport large numbers of Unggoy and Kig-Yar. The barges can be overloaded, causing them to crash, which was a normal occurrence on High Charity. On High Charity, they were controlled by the city's transportation grid. Many higher ranking members in the Covenant have their own personal gravity barge for their own use.
