The multifunctional Don radar had a shape of a truncated pyramid with equal length and width (100 meters), and height of 45 meters. Phased arrays with diameter of 16 meters each were mounted on four sides of the pyramid. Along with the digital processing of incoming signals and information, this radar features an antimissile missile control channel and a wide range of probing signals, making its operation possible in various modes. The resolution characteristics of the radar are excellent, and it can see space objects a few centimeters in size.

Building of the radar began in 1978, and it reached full operational capability around 1989. The modified Don 2NP large multifunction phased-array radar at Pushkino is an integral part of the A-135 Moscow ABM system. The radar, which has 360-degree coverage, provides support for GAZELLE and GORGON interceptor systems.
