Non-combat roles of military aircraft include
search and rescue,
reconnaissance,
observation/surveillance,
Airborne Early Warning and Control,
transport,
training, and
aerial refueling. Many civil aircraft, both fixed wing and rotary wing, have been produced in separate models for military use, such as the civilian
Douglas DC-3 airliner, which became the military
C-47 Skytrain, and British "Dakota" transport planes, and decades later, the USAF's
AC-47 Spooky gunships. Even the fabric-covered two-seat
Piper J-3 Cub had a military version.
Gliders and
balloons have also been used as military aircraft; for example, balloons were used for observation during the
American Civil War and during
World War I, and
military gliders were used during
World War II to deliver ground troops in
airborne assaults.
Military transport transport aircraft Military transport (logistics) aircraft are primarily used to transport troops and war supplies. Cargo can be attached to pallets, which are easily loaded, secured for flight, and quickly unloaded for delivery. Cargo also may be discharged from flying aircraft on
parachutes, eliminating the need for landing. Also included in this category are
aerial tankers; these planes can refuel other aircraft while
in flight. An example of a transport aircraft is the
C-17 Globemaster III. A World War II example would be the
C-47. An example of a tanker craft would be the
KC-135 Stratotanker.
Transport helicopters and
gliders can transport troops and supplies to areas where other aircraft would be unable to land. Calling a military transport aircraft a "cargo plane" is inaccurate, because military transport planes are able to carry
paratroopers and other personnel.
Airborne early warning and control AEW&C aircraft An airborne early warning and control (AEW&C) system is an airborne radar system designed to detect aircraft, ships and ground vehicles at long ranges and control and command the battle space in an air engagement by directing fighter and attack aircraft strikes. AEW&C units are also used to carry out surveillance, including over ground targets and frequently perform C2BM (command and control, battle management) functions similar to an Airport Traffic Controller given military command over other forces. Used at a high altitude, the radars on the aircraft allow the operators to distinguish between friendly and hostile aircraft hundreds of miles away. AEW&C aircraft are used for both defensive and offensive air operations, and are to the NATO and American trained or integrated air forces what the
combat information center is to a
naval vessel, plus a highly mobile and powerful radar platform. The system is used offensively to direct fighters to their target locations, and defensively in order to counterattacks by enemy forces, both air and ground. So useful is the advantage of command and control from a high altitude, the United States Navy operates AEW&C aircraft off its Supercarriers to augment and protect its carrier
combat information center (CICs). AEW&C is also known by the older terms "airborne early warning" (AEW) and "airborne warning and control system" (AWACS, /ˈeɪwæks/ ay-waks) although AWACS is the name of
a specific system currently used by NATO and the USAF and is often used in error to describe similar systems.
Reconnaissance and surveillance reconnaissance aircraft Reconnaissance aircraft are primarily used to gather intelligence. They are equipped with cameras and other sensors. These aircraft may be specially designed or may be modified from a basic fighter or bomber type. This role is increasingly being filled by
military satellites and
unmanned aerial vehicles (UAVs). Surveillance and observation aircraft use radar and other sensors for battlefield surveillance,
airspace surveillance,
maritime patrol, and
artillery spotting. They include modified civil aircraft designs, moored balloons and UAVs.
Experimental Experimental aircraft are designed in order to test advanced aerodynamic, structural, avionic, or propulsion concepts. These are usually well instrumented, with performance data telemetered on radio-frequency data links to ground stations located at the test ranges where they are flown. An example of an experimental aircraft is the
Bristol 188. ==See also==
