A surveillance aircraft is an aircraft used for surveillance—collecting information over time. They are operated by military forces and other government agencies in roles such as intelligence gathering, battlefield surveillance, airspace surveillance, observation (e.g. artillery spotting), border patrol and fishery protection. This article concentrates on aircraft used in those roles, rather than for traffic monitoring, law enforcement and similar activities.
Surveillance aircraft usually carry no armament, or only limited defensive armament. A surveillance aircraft does not necessarily require high-performance capability or stealth characteristics. It may be a modified civilian aircraft. Surveillance aircraft have also included moored balloons (e.g. TARS) and Unmanned Aerial Vehicles (UAVs).
Definitions[edit | edit source]
The terms “surveillance” and “reconnaissance” have sometimes been used interchangeably, but, in the military context, a distinction can be drawn between surveillance, which monitors a changing situation in real time, and reconnaissance, which captures a static picture for analysis.
Observation was the term used for surveillance when the main sensor was the human eye.
History[edit | edit source]
Pre World War I[edit | edit source]
In 1794, during the Battle of Fleurus, the French Aerostatic Corps balloon L'Entreprenant remained afloat for nine hours. French officers used the balloon to observe the movements of the Austrian Army, dropping notes to the ground for collection by the French Army, and also signalled messages using semaphore.
World War I[edit | edit source]
One of the first aircraft used for surveillance was the Rumpler Taube during World War I, when aviators like Fred Zinn evolved entirely new methods of reconnaissance and photography. The translucent wings of the plane made it very difficult for ground based observers to detect a Taube at an altitude above 400 m. The French also called this plane "the Invisible Aircraft", and it is sometimes also referred to as the "world's very first stealth plane". German Taube aircraft were able to detect the advancing Russian army during the Battle of Tannenberg (1914).
World War II and later[edit | edit source]
During World War II, light aircraft such as the Auster were used as air observation posts. Officers from the British Royal Artillery were trained as pilots to fly AOP aircraft for artillery spotting. The air observation role was generally taken over by light observation helicopters, such as the Hughes OH-6 Cayuse, from the mid-1960s.
Roles[edit | edit source]
Maritime patrol[edit | edit source]
Maritime patrol aircraft are typically large, slow machines capable of flying continuously for many hours, with a wide range of sensors. Such aircraft include the Hawker-Siddeley Nimrod, the Breguet Atlantique, the Tupolev Tu-95, the Lockheed P-2 Neptune and the Lockheed P-3 Orion/CP-140 Aurora.
Law enforcement[edit | edit source]
Battlefield and airspace surveillance[edit | edit source]
Current use[edit | edit source]
Unmanned (UAV) surveillance aircraft have been deployed or are under development in many countries, including Israel, the UK, the United States, Canada, China, South Africa, Pakistan and India.
Most air forces around the world lack dedicated surveillance planes.
