One of the most top secrets of the Soviet Union - "Duga 1" or so-called product "5N32", was created to ahead the anti missile shield of the country. In total, the nuclear weapon race between the USSR and USA provoked construction of three antennas like that, at least publicly declared. The experimental object "Duga-H" was at Nikolaev (Ukraine); military garrison at 1,500 personnel at Chernobyl with the name of the complex "Duga 1" (Ukraine); receiving antenna complex in the village of Big Cartel, under the Komsomolsk-on-Amur (Russia).
Due the unique design the antenna was able to detect air targets in the western distance of 900 to 3,000 kilometers. Technological configuration of the complex had been divided into two antennas and auxiliary system "Circle". The radar was created on the principle of a phased array antenna. At the heart of the military garrison there is the command center to control radar installation and training centers - to ensure proper training of officers. Truly monumental antenna «Duga 1» has a total length of about 700 meters in length. Low-frequency large antenna`s height is 150 meters, and the high-frequency- respectively 90 meters. The device worked in the frequency range 5-28 MHz. Auxiliary system back-inclined sounding "Circle" was designed to detect strategic bombers.
According to various information, the construction site was chosen as an object on purpose. Chernobyl nuclear power plant could provide power to complex of antennas «Duga 1". Information dubious, but nevertheless it can be said that the cost of energy is about 30 megawatts! And the estimated cost of the project was about7 billion Soviet rubles - double cost of the Chernobyl Nuclear Power Plant construction.
The antenna was tested first in 1980, but the frequency range of "Duga 1" coincides with the operation of aircraft systems, which caused a lot of resentment on the part of the European Community. The problem was resolved after the upgrade, but the accident on ChNPP in April, 1986…… The military unit was disbanded in 1988, as part of the equipment exported to the antenna station near Komsomolsk-on-Amur.
All our radioactive tourists can personally see this object in the tour.
Touch the history of these places, touch (!) Duga-1 personally :), pass through the long corridors of cable systems, and to make great photos for personal archives can be very easy: just sign up for any date in the calendar of tours. Join of our Radioactive Team!
We also offer a more extensive program of complex and the military town of Chernobyl-2 as the photo tours.
