A Spaceport is a large space station that serves as the primary defense of inhabited planets as well as those planets' orbital construction facility. It can construct ships and modules which upgrade the spaceport itself. Spaceports can be upgraded in order to allow construction of larger ships and additional spaceport modules. A newly built spaceport has two modules slots, one of which is taken up by its defense system. Each additional level unlocks another module slot to a maximum of seven at level five. Each spaceport level also increases its damage and defensive capabilities.


Modules are unlocked through research, apparently often from rare technologies. Some are also limited to empires with certain ethics. Modules have a wide variety of effects. For example defense, economical benefit or ship support. Certain modules are needed to exploit strategic resources.
