The intention was to cover the North West approaches where German long range Focke-Wulf Fw 200 Condor aircraft were threatening shipping. AEW&C systems communicate with friendly aircraft, vectoring fighters towards hostile aircraft or any flying unidentified object, providing data on threats and targets, help extend their sensor range and make offensive aircraft more difficult to track, since they no longer need to keep their own radar active (which can be detected by the enemy) to detect threats.Īfter having developed Chain Home-the first ground-based early-warning radar detection system-in the 1930s, the British developed a radar set that could be carried on an aircraft for what they termed "Air Controlled Interception".
Three such aircraft in overlapping orbits can cover the whole of Central Europe. Modern AEW&C systems can detect aircraft from up to 400 km (220 nmi) away, well out of range of most surface-to-air missiles. Wellington Ic "Air Controlled Interception" showing rotating radar antenna The first known aerial engagement with both opposing sides using Airborne Early Warning and Control aircraft was in the Indian Subcontinent, during the February 2019 aerial engagements between India and Pakistan, with India using A-50I Phalcon and DRDO Netra and Pakistan using the Saab 2000. The first known ACI aerial engagement was with a US Lockheed EC-121 Warning Star AEW&C aircraft against Vietnamese Peoples’ Air Force (VPAF) fighters in the Vietnam War. AWACS (Airborne Warning and Control System) is the name of the specific system installed in the E-3 and Japanese Boeing E-767 AEW&C airframes, but is often used as a general synonym for AEW&C. The designation airborne early warning (AEW) was used for earlier similar aircraft used in the less-demanding radar picket role, such as the Fairey Gannet AEW.3 and Lockheed EC-121 Warning Star, and continues to be used by the RAF for its Sentry AEW1, while AEW&C (airborne early warning and control) emphasizes the command and control capabilities that may not be present on smaller or simpler radar picket aircraft. In the case of US Navy, the Northrop Grumman E-2 Hawkeye AEW&C aircraft is assigned to its supercarriers to protect them and augment their onboard command information centers (CICs). So useful is the advantage of command and control aircraft operating at a high altitude, that some navies operate such aircraft from their warships at sea. According to the theory on command and control (C2) in air combat, fighters aided with C2 from ACI are more likely to achieve air superiority in an aerial engagement with fighters either aided by GCI or not aided by either ACI or GCI. The system is used offensively to direct fighters to their target locations, and defensively, directing counterattacks on enemy forces, both air and ground. ĪEW&C aircraft are used for both defensive and offensive air operations, and are to NATO and US-trained or integrated air forces what the combat information center is to a naval warship, in addition to being a highly mobile and powerful radar platform.
Like a ground-based radar, it can be detected by opposing forces, but because of its mobility and extended sensor range, it is much less vulnerable to counter-attacks. When used at altitude, the radar on the aircraft allows the operators to detect and track targets and distinguish between friendly and hostile aircraft much farther away than a similar ground-based radar. AEW&C units are also used to carry out surveillance, including over ground targets and frequently perform BMC2 ( battle management command and control). A Royal Air Force E-3 Sentry over North YorkshireĪn airborne early warning and control ( AEW&C) system is an airborne radar system designed to detect aircraft, ships, vehicles, missiles, and other incoming projectiles at long ranges and perform command and control of the battlespace in an air engagement by directing fighter and attack aircraft strikes in airborne controlled intercepts (ACI).
