8 Highly Secret Soviet Communication Center Under the Ground

Highly Secret Soviet Communication Center Under the Ground

Posted on March 30, 2015 by team


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 staircase inside.

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.

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

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

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.

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

The scheme of call signs.

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

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

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.

Here they cooked food.

And here they washed dishes.

They had fridges for food storage.

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.

They had sixteen ventilation systems in the bunker.

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

Cyclone filter for primary purification.

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

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

The machines provided the required temperature and humidity.

Some systems had motorized dampers.

They could activate the system manually too.

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

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

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

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

Compressor and two receivers for surge control.

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

Life-support related schemes hang on the walls.

All premises of the level are provided with hermetic doors.

Pumping stations. Red water lines were used for firefighting measures, blue ones for drinking…

Water was also used to cool down the equipment.

The object has four its own artesian wells.

Equipment for pumping excremental and industrial wastes.

Freon based fridges used for water cooling.

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

Each compressor was connected with the receiver.

Freon and water were pumped through the heat exchangers.

Manometers.

The system was powered by the diesel generator.

High voltage required huge switches.

Huge complicated control panel.

Accumulator room.

The main switchboard.

The switchboard is mounted on a platform suspended under the ceiling on absorbers. It was necessary to protect the equipment in case of seismic waves impact.

Spare parts.

Starting device for the diesel generators (one of the three).

Workplace for the duty shift operator.

The important room with three 500 kW ship diesel generators.

Once they were even used to power the nearby district with population of eight thousand people. They necer activated all three generators at the same time.

The main fuel reserve was stored in two 60 m3 capacities.

Electric compressor to pump the air.

Manometers.

Huge exhaust plants to provide continuous air recirculation.

The control room: all ventilation systems, hatches and doors are under control!

The circuit of the water supply system.

Workplaces of a technician and a communications man.

Here the technicial could set the particular mode of bunker functioning depending on combat readiness.

Each mode was provided with its own table of systems configuration.

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

He could contact any man on duty in the bunker.

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!

    Nice Its still everything working?:)

    my gosh this place is amanzin, i still cant belive all this stuff they made up almost for nothin

    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?

    Thanks for this post ER. This is the stuff that first brought me to ER.

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

  6. Darius says:

    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.

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

    Still cant believe that one pretty much a simpleton of a man was allowed to destroy the great USSR.
