Photographer's Note

After the collapse of the Soviet Union in 1991, more than 150 submarines were put out of duty; most of them in 1995. Only rarely, the Russian government, in agreement with the secret service, allowed those to be established as a museum.
U-434, whose Russian description is B-515, was used for special missions: dangerous submarine chases during the naval blockade of Cuba, secret spy missions at the east coast of the United States as well as patrolling territorial waters of the Soviet Union.
This submarine belonged to the Russian Navy for 26 years, until April 2002. After a comparably short negotiation period, it was bought by U-Bootmuseum Hamburg.
U-434 is one of the very few submarines of the Tango class still existing in the world today. It is estimated that 20 submarines were produced, three of those and among them U-434 were specially customized.
The Russian Tango class submarines (Project 641B Som [Catfish]) were the successors to the Foxtrot class submarine based in the Black Sea and Northern Fleet areas. The first of the class was completed in 1972 at Gorky. A total of 18 were built in two slightly different versions. The later type was several metres longer than the first possibly because of installation of ASW missile equipment.
The bow sonar installations appear to be similar to those fitted into Soviet nuclear attack submarines. The propulsion plant was the same as the last subgroup of the Foxtrot class submarine. The Tango class had far more battery capacity, far higher than previous conventional submarine class in the Soviet Navy. As a result, pressure hull volume increased. This allowed an underwater endurance in excess of a week before snorkeling was required.
Coupled with new armament and sensor fit, the Tango class were ideal for ambush operations against Western nuclear submarines at natural chokepoints.
Because of its all-hull rubber coating, the sub class was nicknamed "rezinka" [rubber].
