The Planetary Fortress is a static defense upgrade to the Command Center that requires an Engineering Bay to construct. The Planetary Fortress is a defense-oriented upgrade that has three aspects: more armour, a splash attack, and more SCV garrison space; the upgrade does not actually increase health. It has none of the Orbital Command abilities and cannot lift off. The Planetary Fortress is commonly used on distant expansions to prevent against harassment from units such as Hellions, Zealots or Zerglings.

Compared to the usage of Orbitals, the requirement for an Engineering Bay and the extra gas cost means they are not typically used at expansions until the late game. However, the Planetary Fortress Rush has also been employed in some cheese strategies[1], such as in DiggitySCs' wildly famous 1000th commentary video [2]. TheLittleOne often used Planetary Fortresses as static defenses towards the end of his games when he was high on resources. This was before he switched to Zerg in October of 2010.

The Planetary Fortress has three splash radius. From the target, units until a distance of .5 are dealt 40 damage, units at a distance of .5 to .8 are dealt 30 damage, and units at a distance of .8 to 1.25 are dealt 15 damage. Unlike Siege Tanks, splash damage from a Planetary Fortress does not harm friendly units. Thus, it is not possible for an enemy to kill SCVs simply by parking a unit in the mineral line of a Planetary Fortress.

The Planetary Fortress is affected by the Hi-Sec Auto Tracking upgrade. Hi-Sec Auto Tracking increases the range of Missile Turrets, Auto-Turrets and the Planetary Fortress by +1. If targeted by Blinding Cloud, the Planetary Fortress will have its range reduced to 1.
