Overview of IL-76-Based AEW&C Variants A-100, KJ-2000, A-50 AEW&C and A-100 AEW&C Introduction The latest Russian airborne early warning and control (AEW&C) aircraft, the Beriev A-100, is based on the Ilyushin IL-476 (IL-76MD-90A) transport aircraft. First flown in 2017, the A-100 AEW&C recently completed testing and is slated for production, with 39 units planned to replace the aging A-50 AEW&C aircraft. The A-100 features a rotating phased-array antenna produced by Vega and integrated with the Premier 476 AESA radar, capable of identifying and detecting aerial targets up to 600 km away and ground targets up to 400 km away. In China, the KJ-2000 AEW&C aircraft, also based on the IL-76 transport, utilizes an indigenously developed active electronically scanned array (AESA) radar capable of detecting fighter-sized targets at distances of up to 470 km. These developments highlight the significant advancements in AEW&C capabilities based on the IL-76 platfo...
