Item Database:Planetary Infrastructure:Command Centers
From Backstage Lore Wiki
After the Incursion expansion, all graded command centers will be replaced by a single upgradable comand center for each planet type. The skill Command Center Upgrades used to dictate which level of Command Center you could deploy; now it dictates to what level you can upgrade your Command Center, which initially has zero CPU and powergrid capacity when you first deploy it to a planet.
