The Firebee was the most widely used jet target drone in the world, with more than 4,500 systems built by Ryan. Remotely controlled, Firebees are used as realistic "flying bull's-eyes" that simulate enemy jet aircraft to challenge the missile-firing skills of jet pilots and ground crews. This photo shows four subsonic Firebees ready for launch from a Lockheed DC-130.
