Space Port

Space Ports are orbital shipyards built by and at colonies to construct virtually every ship type.

In addition to the basic starbase components, Space Ports require the following: As a Space Port forms the centerpiece of a colony's orbital presence, it often includes a Medical Center, a Recreation Center, Research Labs, weapons, and defenses.
 * Commerce Center
 * Construction Yard (generally in multiples of 3, to match the Plants)
 * Weapon Plant (1 per 3 Construction Yards, rounded up)
 * Energy Plant (1 per 3 Construction Yards, rounded up)
 * HighTech Plant (1 per 3 Construction Yards, rounded up)

There is no official distinction between "Small", "Medium", or "Large" Space Ports, other than that "Small" designs can upgrade into "Medium" ones (and "Medium" into "Large").
