Constructing a starbase requires first fully surveying the desired system. The build cost is 100 {{iconify|Alloys}} and an additional {{iconify|influence|21px}} cost on top of that. The influence cost is determined by a fixed cost which is then multiplied by the shortest path of hyperlane jumps (gates and wormholes act as "shortcuts") between the target systems and the empire's closest owned system.

Once built, the starbase will appear orbiting the center point of the system. It cannot be destroyed by any regular means but it can still be dismantled by its owner during peacetime if it is of no more than outpost level (higher-level starbases will need to be downgraded first) and the system is not colonized. If a starbase is dismantled, the system reverts to being neutral and unclaimed and can then claimed by any empire.

Besides the initial influence cost, upgrading the starbase to a higher level above outpost level will cost only alloys. Aside from making the starbase more powerful due to better base stats and the addition of more weapon components, the upgrade also allows the owner to fit the starbase with different buildings and modules to increase its defensive capabilities and improve its contribution to the empire beyond its basic role of system control and defense. One such important module is the {{icon|starbase|21px}} Shipyard which enables the construction of military ships in the starbase. Having multiple shipyards on a starbase allows it to effectively act as a "fleet manufactory" by constructing several ships in parallel, simultaneously. Shipyards build order is independent from the main build order of starbase.

Though it is not possible to design a starbase, its components will be auto-fitted with the latest advanced technology as soon as they are made available (at no additional cost to the owner).

=== Starbase capacity ===
An empire can in theory have as many starbases as their economy can support but an empire can only maintain a limited number of upgraded starbases bigger than outposts. The number of upgraded starbases an empire can support is dictated by the starbase capacity and exceeding that capacity will cause all upkeep costs for starbases to increase by {{red|+25%}} {{iconify|Upkeep|21px}} for every starbase exceeding the cap. This is an empire-wide modifier, and thus affects all starbases owned by the empire. This modifier also affects the maintenance of any modules and buildings on the starbases. Regardless of their level, each starbase bigger than an outpost occupies only one capacity slot and if the need arises, an empire can always downgrade existing starbases back to outpost level to reduce the number of upgraded starbases to within the cap limit.

The base starbase capacity is 3, which can be increased by the following:
* {{green|+1}} for every 10 systems owned by the empire
* {{green|+2}} {{icon|tradition}} adopting the Unyielding tradition tree
* {{green|+2}} [[File:Tradition_unyielding_fortress_doctrine.png|21px]] Fortress Doctrine from [[File:Tradition icon unyielding.png|21px]] Unyielding tradition tree
* {{green|+2}} {{iconify|Stellar Expansion|24px}} technology
* {{green|+2}} {{iconify|Manifest Destiny|24px}} technology
* {{green|+2}} {{icon|edict}} Fortify the Border edict
* {{green|+4}} {{iconify|Trading Posts}} civic
* {{green|+5}} [[File:ap grasp the void.png|24px]] Grasp the Void ascension perk
* {{green|+10}} [[File:Mod shroud unavailable.png|24px]] Covenant: End of the Cycle
* {{green|+1}} {{iconify|Interstellar Expansion|24px}} repeatable technology (can only be researched 5 times)
* {{green|+2}} for each Strategic Coordination Center level, except the site of the megastructure  (Total: {{green|+6}})
