In the 1st hall: Models of submarines, which allows tracing the stages of development of submarines in our country, a model of the D-2 submarine museum, a 45 cm torpedo from the Great Patriotic War and small arms of the Marine Corps for the defense of Leningrad in 1941-1944. Samples of the aft Naval flag and the Huys of the Workers' and Peasants' Red Fleet, raised on ships in the period from 1923 to 1935.
In the 2nd hall: A story about the equipment and ways submariners fight for their lives when a submarine crashes and it is necessary to rescue the crew on their own. An individual diver's rescue equipment, a buoy for surfacing from a depth of up to 100 m without decompression sickness. The breech of the 53 cm caliber torpedo tube shows the storage and launch of torpedoes from a submarine.
In the 3rd hall: The berth of the Kronstadt submarine connection and a sample of a galvanic shock naval mine. Such mines were massively used by all sides during the Great Patriotic War, and the Baltic Sea was filled with them like "soup with dumplings." Therefore, the losses of submarines of the Soviet KBF are almost twice as high as the losses of other fleets.
