Savant missile
Savant missiles were anti-aircraft projectile weaponry capable of being fired from the PLX-4 Missile Launcher. They were classed as "surprise attack" weapons and when fired appeared to be little more than "dumb" missiles, easily avoided by a pilot with a few simple maneuvers. However, when launched, savant missiles "tagged" the intended target with its on-board computer system; after five seconds, the missile's guidance system activated and homed in on the target.
