The Indian Air Force (IAF), is looking at 12 early warning aircraft under two different programmes.
It is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack aircraft.
AEW&C units are also used to carry out aerial surveillance over ground and maritime targets, and frequently perform battle management command and control (BMC2).

Feature |
Description |
|
Detection Range |
Can detect aircraft up to 400 km (220 nmi) away, out of range of most surface-to-air missiles. |
|
Coverage with Multiple Aircraft |
Three aircraft in overlapping orbits can cover the whole of Central Europe. |
|
Proximity Detection |
Indicates both close and far proximity range on threats and targets. |
|
Sensor Extension |
Helps extend the range of sensors, aiding in offensive operations by making aircraft harder to track. |
|
Radar Stealth |
Reduces the need for offensive aircraft to keep their own radar active, minimizing enemy detection. |
|
Communication Capabilities |
Communicates with friendly aircraft, directing fighters towards hostile or unidentified flying objects. |
