Spaceport industry
Facilities for loading and unloading cargo and performing basic starship repairs. A colony without a spaceport is virtually inaccessible to interstellar trade.

–In-game description

A Spaceport is a structure. Its construction is automatically begun for free at all colonies, or can otherwise be built manually if destroyed.

A spaceport costs 50 000 credits to construct, and has a build time of 15 days.



Note: A spaceport, or its upgrade Megaport, provide the majority of a colonies' accessibility, both directly and by removing the -100% accessibility penalty from the lack of a spaceport, thus making exports or imports without one nigh-impossible.


Spaceports have a base upkeep of 1500 credits, increasing by the same amount for each colony size past 3.

A spaceport will incur an upkeep penalty if the demand for Fuel, Supplies, or Ship Hulls & Weapons is not met. The penalty is a 10% increase to upkeep per unit of the largest shortage amount.


Spaceports produce the following commodities;

  • Crew; equal to colony size, minus one


Spaceports demand the following commodities;

AI CoresEdit

Spaceports receive the following perks from the assignment of an AI Core;

  • Gamma; reduces demand by one unit
  • Beta; reduces demand by one unit, reduces upkeep by 25%
  • Alpha; reduces demand by one unit, reduces upkeep by 25%, increases accessibility by an additional 20%


  • The Spaceport and its upgrade Megaport are the only structures (including industries) in the game to suffer an upkeep penalty for any reason besides the colony's hazard rating.
  • Despite starting construction automatically when a colony is established, similar to Population & Infrastructure which is present on every civilized colony, spaceports can be destroyed without immediately decivilizing the colony and can be manually shut down by the player.
