Big planes - An-124 "Ruslan", "Mriya" is standing in the hangar to the right. You can see its tail on the picture above.
This object is called "Chernobyl-2". Twenty seven years ago it was an absolutely secret object. It allowed to follow ground targets over Europe and not only, detect launches of a potential enemy in North America. The complex was called "Duga-1".
The first complex like this was built in 1975 in Komsomolsk-on-Amur, Russia. It was first activated in Chernobyl-2 in 1980. According to some data there was invested seven billion rubles (two times more expensive than the construction of the Chernobyl NPP). There was built a garrison not far from Chernobyl where militarymen and their families used to live.
The infrastructure of the city Chernobyl-2 did not happen in a moment - it had been closed until 1987. Then it became clear it could not be used anymore in the exclusion zone. The main units were dismantled and taken to Komsomolsk-on-Amur.
Five Ukrainian base-jumpers jumped from the station in 2012 for the first time.
