20th+: UAVs

UAVs include both autonomous (capable of operating without human input) drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty first century technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation.

An unmanned aerial vehicle (UAV) or uncrewed aerial vehicle, commonly known as a drone, is an aircraft without a human pilot on board. UAVs are a component of an unmanned aircraft system (UAS), which include additionally a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator ― remotely-piloted aircraft (RPA) ― or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that does not allow human intervention.

Compared to crewed aircraft, UAVs were originally used for missions too "dull, dirty or dangerous" for humans. While drones originated mostly in military applications, their use is rapidly finding many more applications including aerial photography, product deliveries, agriculture, policing and surveillance, infrastructure inspections, science, smuggling, and drone racing.

A UAV differs from a cruise missile in that a UAV is intended to be recovered after its mission, while a cruise missile impacts its target. A military UAV may carry and fire munitions on board, while a cruise missile is a munition.

The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, serving as a balloon carrier (the precursor to the aircraft carrier) is the first offensive use of air power in naval aviation. The first pilotless aircraft were built during WW1. From a suggestion that A. M. Low’s expertise in early television and radio technology be used to develop a remotely controlled pilotless aircraft to attack the Zeppelins a remarkable succession of British drone weapons in 1917 and 1918 evolved. After WW1, three Standard E-1s were converted to drones. The Larynx was an early cruise missile in the form of a small monoplane aircraft that could be launched from a warship and flown under autopilot; it was tested 1927-9 by the Royal Navy. The early successes of pilotless aircraft led to the development of radio controlled pilotless target aircraft in Britain and the US in the 1930s. In 1931, the British developed the Fairey Queen radio-controlled target from the Fairey IIIF floatplane, building a small batch of three, and in 1935 followed up this experiment by producing larger numbers of another RC target, the "DH.82B Queen Bee", derived from the de Havilland Tiger Moth biplane trainer.

The attitude towards UAVs, which were often seen as unreliable and expensive toys, changed dramatically with the Israeli Air Force’s victory over the Syrian Air Force in 1982. Israel’s coordinated use of UAVs alongside manned aircraft allowed the state to quickly destroy dozens of Syrian aircraft with minimal losses. Israeli drones were used as electronic decoys, electronic jammers as well as for real time video reconnaissance.

The US military is entering a new era in which UAVs will be critical to SIGINT payloads, or Electronic countermeasures systems should be in widespread use following 2010, with the UAVs controlled and relaying data back over high-bandwidth data links in real time, linked to ground, air, sea, and space platforms. The trend had been emerging before the American war in Afghanistan began in 2001, but was greatly accelerated by the use of UAVs in that conflict. The Predator RQ-1L UAV (General Atomics) was the first deployed UAV to the Balkans in 1995 Iraq in 1996 and was proved very effective in Operation Iraqi Freedom as well as Afghanistan.

Endurance UAVs for low-altitude and high-altitude operation, the latter sometimes referred to as "high-altitude long-endurance (HALE)" UAVs, are now in full service. On August 21, 1998, an AAI Aerosonde named Laima becomes the first UAV to cross the Atlantic Ocean, completing the flight in 26 hours. The idea of designing a UAV that could remain in the air for a long time has been around for decades, but only became an operational reality in the 21st century.

The Government of Canada is considering the purchase of UAV's for arctic surveillance. The Canadian government wants to buy at least three high-altitude, unmanned aerial vehicles in what could be an attempt to salvage its Arctic sovereignty ambitions. The Canadian government wants to modify the existing Global Hawk drone, which can operate at 20,000 metres, to meet the rigours of flying in Canada's Far North.

Armed drones are growing in military importance as conflicts around the world have proven the utility of these effective tools of war. Demand is surging beyond the U.S. for the multibillion dollar armed-drone market. Companies in China, Turkey, and Russia, among others, have developed advanced remotely piloted aircraft that can use guided weapons on and off the battlefield. Over 100 states worldwide using military drones and that number is growing significantly. Over 20 states are using armed drones in conflicts or outside of armed conflicts.

The widespread use of drones in Iraq and Afghanistan by the United States to target and kill insurgents jump started a new chapter in the history of conflict. These high flying and remotely piloted aircraft could engage targets with impunity while the operators were safely working in a ground control station. Keeping the crews out of danger also made the drones politically cheap to use over dangerous skies. Now more and more countries are gaining this military capability for their own purposes.

Although larger and more complex drones, like the General Atomics MQ-9 Reaper are not cheap to develop or operate, smaller drones are becoming more ubiquitous in conflict zones. Limiting the proliferation of these smaller drones, and the ability to weaponize them, is a regulatory nightmare for government agencies around the world.

Drones are model airplanes with great sensors. All are dual use and have been used in the civilian realm. Drones have risen enormously in the civilian realm over the last five to 10 years. Controlling their export is very difficult.
