A radar that is able to track targets at ranges of over 3,000 km has been activated within the Russian air defense system on Dec. 2, 2013.
The Kolkino radar station, using the first modernized 29B6 radar, is able to track aerial targets flying as far aways as Denmark. Earlier the radar had a research role only, and even if full operational capability is expected within 2 years, the new system is already keeping an eye on what flies west of the Russian border.
The radar is made of 150 antenna masts, data transmission systems, transmitters and receivers, power station and control building. The peculiarity of the system is that it is able to detect both high altitude targets, such as ICBMs (Inter Continental Ballistic Missiles), as well as low altitude flying air traffic, at very long distances, well beyond the line of sight.
Provided technical specifications will be confirmed, Russia will soon be able to monitor almost everything flying over eastern Europe, and beyond.
