The KongJing-2000 (KJ-2000) Airborne Early Warning and Control system (AEW&C) was developed to meet the requirements of People's Liberation Army Air Force (PLAAF) for an early warning aircraft.
The KJ-2000 is based on the A-50/IL-76MD with indigenously developed Active Electronically Scanned Array (AESA) radar. Airborne AESA radar for the KJ-2000 was developed by Nanjing Research Institute of Electronic Technology.
The KJ-2000 uses three AESA radars in the radome above the fuselage ESM fairings on the wing-tips of the aircraft. The KJ-2000 can be fitted with the aerial refuelling probe to increase the endurance of the aircraft.
Its AESA radars are speculated to be using L-band array Transmit-Receive module. Three radars allow the KJ-2000 to provide 360 deg radar coverage.
