AGM-114 Hellfire

The Hellfire missile was a type of air-to-surface missile used by American unmanned aerial vehicles. The MQ-1 Predator carried six Hellfire missiles.

During Day 9, Lieutenant Chris Tanner was flying the MQ-1 Predator from Lower Heyford Air Force Base. His mission was to provide reconnaissance to a convoy led by his superior Major Shepherd. However, after finishing his mission, someone took control of his drone and armed one of the Hellfire missiles. Although Tanner tried to alert Shepherd by phone, the drone fired the missile and destroyed one of the convoy's APC. The attack resulted in four casualties.

Jack Bauer and Chloe O'Brian later learned that a hacker called Derrick Yates had developed an override system that allowed him to take control of American drones, each of which carries six Hellfire missiles.
