General Characteristics

The Beriev A-50 is a Soviet/Russian Airborne Early Warning and Control (AEW&C) aircraft, often referred to by its NATO reporting name Mainstay. It was developed to replace the Tupolev Tu-126 “Moss” and is based on the robust Ilyushin Il-76 transport airframe. Its primary function is to detect and track airborne and surface targets at long ranges, and to serve as an aerial command post, guiding friendly fighter aircraft during engagement. Its most distinctive feature is the large rotating saucer-shaped radome mounted above the fuselage.
