1910s & 1920s
Tesla describes unmanned aerial combat vehicles (1915)
RAF Aerial Target (UK, ) designed for defense against Zeppelins, and as a flying bomb
Sperry Aerial Torpedo (USA, ) incorporated A gyro-stabilizer, automatic steering gyroscope, a barometer, and an engine-revolution counter.
RAE LARYNX (UK, ) engine produced 200Hhp; top speed 320kph faster than fighters of the time, armed with a 113 kg warhead.

3. 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.

4. HISTORY 1970s & 1980s 1990s to Present
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.

HALE (high altitude, long endurance) over 30,000 ft alt. and indefinite range
HYPERSONIC high-speed, supersonic (Mach 1–5) or hypersonic (Mach 5+) 50,000 ft or suborbital alt., range over 200 km
ORBITAL low earth orbit (Mach 25+)
CIS Lunar Earth-Moon transfer
CACGS Computer Assisted Carrier 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.
