Highly Secret Soviet Communication Center Under the Ground

Government and military communication has been important in all times. In the time of a cold war it was crucial to provide faultless information transfer even in the conditions of a nuclear conflict. With such a purpose the system of fortified undeground communication centers was created in the USSR. They were used to transfer the commands to the western force groups located in the Warsaw Pact countries and elsewhere. Today we’re going to show the pictures taken by a blogger deletant who visited one of such centers.

It used to be a military unit that consisted of two signal centers: the one was used to receive signals, another one to transfer them. Each center was represented by a three-level underground structure with independent life-support systems, surrounded by the reliable dual signalling system along the entire perimeter.

On the image above you can see the main entrance to the bunker and ventilation structures in the background.

The bunker was built in 1968-71.

This massive door can protect from a shock wave of an atomic explosion. Its mass is 3 tons. To get inside one had to dial a telephone number and say the password to the guard.

We get inside and see another smaller pressurized safety door.

And a telephone on the wall.

Behind the second door we find the third telephone, fire hydrant and panel for sealed valves control.

An airlock system is intended to protect the bunker from poisoning substances.

These long corridors make you think you are in a submarine. The object is divided into three levels, each is 1200 m2.

Highly Secret Soviet Communication Center Under the Ground

The upper level is fully occupied by the systems of information transfer. A lot of radio equipment is still here.

Highly Secret Soviet Communication Center Under the Ground

There was an antenna field around each bunker. Connection with the antennas and the nearest objects was provided by reliable cable lines.

Highly Secret Soviet Communication Center Under the Ground

Through different communication canals information was received in the huge line equipment room.  Each unit was used for a particular canal.

Some secret data was encrypted.

Operators were adjusting signals to transfer them further. Above you can see the cup saying “To the best communication center”.

Such devices were used for equipment diagnostics.

The distant communication board is located in the room with sound-proof walls. Here they connected different abonents. Mainly women were doing that.

Highly Secret Soviet Communication Center Under the Ground

From here they could contact any place on Earth and all satellite countries, even Cuba.

They had a special station to make sure that all clocks of the object show the same time.

Highly Secret Soviet Communication Center Under the Ground

The exact time was set by a duplicate system of mechanical electromagnetic clocks.

Highly Secret Soviet Communication Center Under the Ground

In the mid 1980s the system was replaced by new electronic equipment, a signal about the exact time began to be received via the radio canal from the outer source. However that system was broken quite soon and made them return to the old one.

Kitchen.

Highly Secret Soviet Communication Center Under the Ground

Here they cooked food.

Highly Secret Soviet Communication Center Under the Ground

And here they washed dishes.

Highly Secret Soviet Communication Center Under the Ground

They had fridges for food storage.

Highly Secret Soviet Communication Center Under the Ground

Lower bunker levels had nothing to do with data transfer, they were fully used by the independent life-support systems. Here, in the bunker they could stay for 2-3 weeks.

Ventilation systems.

Highly Secret Soviet Communication Center Under the Ground

They had sixteen ventilation systems in the bunker.

Highly Secret Soviet Communication Center Under the Ground

Each system had to purify, cool, dry and moisten the air.

Highly Secret Soviet Communication Center Under the Ground

Cyclone filter for primary purification.

Highly Secret Soviet Communication Center Under the Ground

They had ventilation through carbon filters that could be used during an attack with poisoning substances.

Highly Secret Soviet Communication Center Under the Ground

The air used for equipment cooling was going through the water jet stream in the conditioner of the fridge machines.

Highly Secret Soviet Communication Center Under the Ground

The machines provided the required temperature and humidity.

Highly Secret Soviet Communication Center Under the Ground

Some systems had motorized dampers.

Highly Secret Soviet Communication Center Under the Ground

They could activate the system manually too.

Highly Secret Soviet Communication Center Under the Ground

They had theair reserve with a capacity of 4000 m3 stored in 96 special tanks.

Highly Secret Soviet Communication Center Under the Ground

They still maintain the pressure of 50 atmospheres to prevent the tanks from corrosion.

Highly Secret Soviet Communication Center Under the Ground

Multiple pipes are stretching from the tanks to the next room.

Highly Secret Soviet Communication Center Under the Ground

From here they controlled air transfer from the tanks to the systems of ventilation.

The heaviest equipment for life-support in the bunker was located on level 3.

All premises of the level are provided with hermetic doors.

Freon based fridges used for water cooling.

Highly Secret Soviet Communication Center Under the Ground

Fridge operation was provided by two compressors, receiver, heat exchanger and freon containing tanks.

Highly Secret Soviet Communication Center Under the Ground

Each compressor was connected with the receiver.

Highly Secret Soviet Communication Center Under the Ground

Freon and water were pumped through the heat exchangers.

The operator could block any doors or valves, any water pumps, refridgerators, smoke removal system etc.

Highly Secret Soviet Communication Center Under the Ground

He could contact any man on duty in the bunker.

Highly Secret Soviet Communication Center Under the Ground

The control room is located on a suspended platform too.

Here it is! Rather impressive room.

Let us say thanks to deletant for wonderful photographs!

  1. Great Pictures, rather detailed tour through the bunker complex.Its suprising to see that most of it is in preety good shape . is the bunker stil used for some purposes?

  2. Perfect example how paranoid the Soviet society was. Unfortunately Putin’s regime is becoming more and more like CCCP, seeing enemies everywhere, suspecting everything.

  3. Yes, indeed it is very interesting pictures! Great work!

    My guess is it is in this good condition because it just recently was removed from the list of secret objects? I think so because I see a lot of “casually” dressed people in pictures that do not look like photo or scouting people, but they look like the workers. Such people typically you see doing building or equipment repairs or they do demolition or equipment salvage (or both). So – or this object will be totally renovated or … most likely it has lost its military purpose.

  4. Those manometers look like have radium dials which glow without external light source. Definitely extreme…
