The complex is built accordingly to withstand a category-I nuclear explosion, and includes an underground network of water channels complete with a dry dock, repair shops, warehouses for torpedoes and other weapons. Additionally it could protect personnel from nuclear fallout. The complex is located in the mountain of Tavros, on both sides of which are exits. Caisson gates could be used if necessary to seal the entire complex. An exit to the open sea is provided on the northern side of the mountain. The holes in the rock are neatly covered with camouflage devices and networks. Object 825 GTS was intended to house, repair and maintain Project 613 and 633 submarines. The central water channel of the facility, at a length 602 meters, could accommodate up to 7 submarines if necessary, and up to 14 submarines of different classes in all water channels. The water channels have depths up to 8 meters, with widths ranging from 12 to 22 meters. The total area of all facilities in the complex is around 9600 m2, while the total surface area of water stands at 5200. Equipment loading in peacetime was carried out on the pier, then conducted while watching out for the movements of spy satellites of possible military adversaries. A special tunnel is used for loading equipment into the base in wartime. The complex also includes a repair and technical base, codenamed Object 280, designed for storing and maintaining nuclear arsenal. Submarines could enter and exit the base completely submerged through its underwater access point. Temperature inside the base is kept around 15 degrees Celsius. The Soviet Navy trained dolphins at this facility to attach underwater beacons and explosives to submarines and ships.
History
In the period after the Second World War, the two superpowers, the USSR and the US, stepped up their nuclear arsenal, threatening each other with pre-emptive strikes and retaliatory strikes. It was then when Joseph Stalin gave Lavrentiy Beria, a secret directive; to find a place where they could house submarines for a retaliatory nuclear strike. Several years of research pinpointed the quiet Balaklava as the location, and the city was immediately coded and got merged into the city ofSevastopol as a city district. Balaklava sits on a narrow winding inlet with a width of only 200–400 meters. This small inlet protects the city not only from storms, but also from reconnaissance as it is not visible from any angle from the open sea. Additionally, the site is close to Sevastopol, a major naval base still used by the Russian Navy's Black Sea Fleet today. In 1957 a special construction department coded as No. 528 was created, which handled the construction of underground facilities. The construction of the underground complex lasted eight years, from 1953 to 1961. About 120 thousand tons of rock were removed from the Tavros mountain throughout the process. To ensure secrecy supplies were transported at night on a barge in the open sea. After the complex was closed in 1993, most of the complex is unguarded. The abandoned facility was handed over to the naval forces of the Armed Forces of Ukraine in 2000. However, the former base was frequently plundered during the unguarded period from 1993 to 2003, with all metal structures scavenged for the metal. The Sevastopol "Marine Commission" led by Vladimir Stefanovsky proposed the construction of the current museum. The museum would have themed exhibition halls, which were former repair shops and arsenals, a submarine standing by the underground pier, a tourist center, a cinema room with a chronicle of the time of active military confrontation between the two superpowers, and finally, an underground memorial dedicated to submariners who died at sea. The 10th anniversary of the museum was celebrated in June 2013. Submarine veterans, former employees of the base as well as representatives from the authorities, armed forces and students attended the ceremony. The facility was placed under the jurisdiction of Russia and the southern area of the Military History Museum of fortification structures of the Russian Federation in 2014, after the annexation of Crimea.
Restoration
According to press information from March 2014, Russia is considering the possibility of restoring the submarine base in Balaklava.
Address
The base sits at No.22 Tavricheskaya Naberezhnaya street, Balaklava district, Sevastopol, Crimea.
