A target drone is an unmanned aerial vehicle, generally remote controlled, usually used in the training of anti-aircraft crews.

One of the earliest drones was the British DH.82 Queen Bee, a variant of the Tiger Moth trainer aircraft operational from 1935. Its name led to the present term “drone”.

In their simplest form, target drones often resemble radio-controlled model aircraft. More modern drones may use countermeasures, radar, and similar systems to mimic manned aircraft.

More advanced drones are made from large, older missiles which have had their warheads removed.

In the United Kingdom, obsolete Royal Air Force and Royal Navy jet and propeller-powered aircraft (such as the Fairey Firefly, Gloster Meteor, and de Havilland Sea Vixen used at RAE Llanbedr between the 1950s and 1990s) have also been modified into remote-controlled drones, but such modifications are costly. With a much larger budget, the U.S. military has been more likely to convert retired aircraft or older versions of still serving aircraft (e.g., QF-4 Phantom II and QF-16 Fighting Falcon) into remotely piloted targets for USAF, USN and USMC use as Full-Scale Aerial Targets or FSATs.
