A Starbase is a large, slow-moving orbital space platform. During the Ur-Quan Slave War, starbases were used at by both sides as bases of operation and as mobile shipyards in the various skirmishes and battles. However, starbases themselves lack any defensive weapon systems.
Following the defeat of the Alliance, the Ur-Quan Kzer-Za required each Fallow Slave race to maintain a space station to assist Hierarchy vessels that are in need of repairs or fuel. As such, there is a starbase around Earth, the Syreen homeworld at Betelgeuse I, and the Chmmr/Chenjesu homeworld at Procyon II. These starbases are periodically resupplied by the Ur-Quan Kzer-Za, at which time they also replace the personnel with fresh ones from the slave-shielded planet below.
