Balaklava Submarine Base (Object 825 GTS)
Sevastopol
The Balaklava Submarine Base, also known as Object 825 GTS, is a unique underground naval complex built beneath Mount Tavros in Balaklava Bay, Crimea. Constructed during the Cold War, it was designed to withstand a nuclear explosion and served as a secret Soviet submarine base capable of housing, repairing, and maintaining multiple submarines, including the Whiskey and Romeo classes. The facility features an extensive network of water channels, dry docks, repair shops, and warehouses for torpedoes and nuclear weapons, all concealed within the mountain and protected by caisson gates. Its strategic location on a narrow inlet shielded it from reconnaissance and storms, while underwater access allowed submarines to enter and exit submerged. After its military use ended in 1993, the base was converted into a museum showcasing Cold War naval history, submarine technology, and exhibits on the Crimean War. Visitors can explore the underground tunnels, arsenals, and repair facilities, gaining insight into Soviet naval operations and the tense geopolitical climate of the era. The museum also commemorates submariners who lost their lives at sea and includes displays of military artifacts, models, and technical equipment. Today, it stands as a rare and fascinating testament to Cold War military engineering and maritime heritage.

Histoire
The Balaklava Submarine Base was constructed between 1953 and 1961 following a secret directive from Joseph Stalin to create a secure naval facility capable of withstanding nuclear attacks and housing retaliatory strike submarines.
Its location in Balaklava was chosen for its natural protection and strategic proximity to Sevastopol, a key naval port.
The base remained a top-secret Soviet military installation throughout the Cold War, designed to shelter Whiskey and Romeo-class submarines.
After the dissolution of the Soviet Union, the base lost its military significance and was closed in 1993.
It was later repurposed as a naval museum complex, officially opening in 2003.
Since 2014, following the annexation of Crimea, the museum has been under Russian jurisdiction and continues to preserve and present Cold War maritime history.
