The docking bays consisted of a series of excavated, enlarged, and reinforced craters, in which freighters and starfighters could land. Electromagnetic countermeasure camo-netting was available in storage bunkers near crater rims, by which the contents of craters could be made hidden. The crater bays were connected by a series of tunnels linking surface entrances and underground chambers. Larger bulk freighters and pirate corvettes were forced to land outside the bounds of the security of the craters, in nearby clearings.
