B-515 is a Tango-class submarine of the Soviet and Russian Navies. It remained in active service until 2001. It is currently docked in Hamburg and is open to the public as a museum exhibit. The submarine is sometimes referred to as U-434, which derives from the pennant number painted on the vessel. This submarine was used for hunting, espionage, and patrol purposes. A 78-man crew operated the boat. The submarine U-434 came from the Krasnoye Sormovo submarine shipyard in Nizhny Novgorod and was built in 1976 in just eight months. It was placed in the service of the Soviet Northern Fleet and remained in service until April 2002. Because of the long period in which the vessel was inactive and the extensive modifications made when B-515 became a museum ship, all major systems such as engine and hydraulics were deactivated. It has a six-centimeter thick rubber coating, so it was harder to locate using sonar. More information...
