A fire director or fire control system is a system made to tell anti-aircraft artillery where to fire.

These systems control automatic cannons and surface-to-air missiles to destroy enemy aircraft. For this, computers, sensors and fire control radars are also used to indicate to fire directors where the enemy aircraft are. An example of this type of radar is the ELTA Systems EL/M-2106 of Israeli origin. Examples of fire directors are the Austrian Skyguard, which controls Oerlikon GDF cannons and short-range missiles; and the Swedish Flaycatcher, which tells the RBS-70 the location of its target.

This type of anti-aircraft systems are used by many air forces, armies and navies around the world, and has been developed since World War II with computers in bombers to calculate where the bombs would fall, and their use has been applied to all types of contexts, such as coastal artillery and fire directors on warships.
