Object 28
The Balaklava Soviet Naval Museum also included a large technical and repair base called Object 280. The complex was constructed to store and maintain the nuclear arsenal that was being transported at the time to the tunnels of Tavros Mountain.
Object 280 is a tunnel they used during World War II to load equipment. It made sense, since the 825 GTS was created to maintain and repair Project 613 and Project 633 boats.
