Slava, Soviet submarine museum in Beloslav, Bulgaria.

Slava is a Soviet-era submarine turned museum vessel moored in Beloslav, on the shores of Varna Lake in Bulgaria. The vessel is divided into several compartments, each preserving original equipment and restored crew areas that cover different operational functions.

The submarine was built in 1959 in the Soviet Union and sailed under the name Leninski Komsomol for decades. After the Cold War ended, it was transferred to the Bulgarian Navy and renamed Slava in 1991.

The submarine shows how crews lived and worked in very tight spaces during Cold War operations. Visitors can walk through the galley, sleeping quarters, and command room, which still look much as they did when the vessel was in service.

The passageways on board are narrow and the stairs between compartments are steep, so flat, comfortable shoes are a good idea. Those who feel uneasy in tight, enclosed spaces should know that most of the visit takes place below deck.

The submarine began as the Soviet S-36, yard number 343, built at the Krasnoye Sormovo shipyard in 1959 and handed to the Black Sea Fleet in 1960. Bulgaria received it in December 1985 and enrolled it on 28 December under the pennant number 84 in the 8th Separate Submarine Division.
