The Planetary Fortress is an upgrade to the Command Center that fits a laser cannon atop it to shoot foes, but disables the ability to lift off.
After the Brood War, the increasing use of command centers in combat zones led to the development of standard schematics for upgrading them to a dedicated military role. One such variant is the planetary fortress, featuring increased armor and heavy defensive armament.
It was designed by Ares, a weapon designing company. Structures similar to orbital commands and planetary fortresses were in use by the Kel-Morian Combine by 2502.
