B-39 "Foxtrot" former Sovyet Union submarine

The B-39 submarine was built in 1974 and classified as diesel-electric powered attack submarine. She was one of a fleet of Sovyet attack submarine that shadowed U.S Navy ships throughout the world during the cold war era. As she becomes one of San Diego maritime museum fleet nowadays, visitor is allowed to get onboard into the control room, torpedo room, captain & crew cabins, engine room and targeting 'enemy' use its periscope. Hard to imagine how were the crew activities in this 'very compact' corridor and cabins inside the sub, but you now.. it is a naval life they had to do.
