During the NATO campaign in Yugoslavia, UAVs were employed only for reconnaissance purposes. In Afghanistan, however, troops used a strike craft called the Predator for the first time, detecting and destroying militant groups of various strengths, their bases and sites for launching unguided missiles.

The wide range of available guided weapons makes it possible for UAVs to carry out their missions alone or in conjunction with manned aviation. Because of the enormous payload carried by UAV craft, it is safe to assume that developers will continue to look for ways to make guided aviation weapons smaller.

Directed-energy weapons are also likely to be added to the traditional arsenal of weapons and electronic countermeasures already mounted on UAV craft.

The global spread of UAV technologies has encouraged many do-it-yourself projects using unclassified methods. So these weapons of the future could also be used by terrorists as a sort of kamikaze robots.
