Category:Planetary Defense System

===A Planetary Defense System is a defense based on the surface of a planet or planetoid meant to defend the surface against enemy attacks from space. These countermeasures, like all Defenses, are organized by the defining categories of the defenses such as the weaponry defended against and defense technology used. For example, a  Planet-Based Anti-Projectile Missile (PBAPM)  is a defensive missile based off the surface of a planet or planetoid used to defend against incoming projectiles. ===
