Airborne Early Warning & Control (AEW & C) is a high-performance radar that captures enemy airplanes flying at long distances and reports them to the ground base, and directs and controls friendly fighters. Because of this, it has a nickname as the command of the battle command of the air. The radar onboard the airborne early warning system has better search and detection capabilities than the ground radar. In addition to being able to search 360 degrees in all directions, it is also possible to catch low-altitude low-flying aircraft. In general, the ground radar located at the top of the mountain is the enemy's primary attack target in the exhibition. It can be disabled. On the other hand, the airborne early warning control system is much more viable than the fixed ground radar because it is flying in the air.
