An 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
he NATO E-3A (or AWACS) is a modified Boeing 707 equipped with long-range radar and passive sensors capable of detecting air and surface contacts over large distances. Information collected by AWACS can be transmitted directly from the aircraft to other users on land, at sea or in the air in near real time.
