Pre-Aviation Days Eddy's Surveillance Kite (USA, 1898) takes worlds first wartime
aerial surveillance photos
1910s & 1920s Tesla describes unmanned aerial combat vehicles (1915) RAF Aerial Target (UK, 1916-17) designed for defense against
Zeppelins, and as a flying bomb Sperry Aerial Torpedo (USA, 1916-18) incorporated A gyro-stabilizer,
automatic steering gyroscope, a barometer, and an engine-revolution counter.
RAE LARYNX (UK, 1925-27) engine produced 200Hhp; top speed 320kph faster than fighters of the time, armed with a 113 kg warhead.
HISTORY
1930s & 1940s Small advances but primarily remote controlled aircraft and the V1-V2
rockets which were more closely related to the modern cruise missiles
1950s & 1960s Drones primarily developed as targets for air to air and ground to air
missile training and assessment AQM-34 Ryan Firebee (USA, 1960s) using anti-radar paint its radar
signature was reduced. Between October of 1964 and April of 1975, over 1,000 of these drones flew in over 34,000 surveillance missions over SouthEast Asia, with an 83% recovery rate.
HISTORY 1970s & 1980s
Firebee 1241 (1970s, Israel) In 1970 Israel purchased 12 drones from the U.S., modified them, and re-designated them 'Firebee 1241'. These drones proved vital both as reconnaissance drones, and as decoys, a function not yet used much for drones.
1990s to Present General Atomics Aeronautical Systems RQ-1 Predator (USA, 1996) made into several variants including
the Reaper [an armed UAV or more correctly a UCAV] Drones begin to be man-portable, the smallest of which is 4 inches and 16 grams.

Guidance System for UAVs
Note : The United States military employs a tier system for categorizing its UAVs. The Tiers do not refer to specific models of aircraft but rather roles for which various models and their manufacturers competed.
USES
