The Tango class was the NATO reporting name of a class of diesel-electric submarines that were built in the Soviet Union to replace the Foxtrot-class submarines assigned to the Black Sea and Northern Fleets. The Soviet designation of this class was Project 641B and it was also known as the Som (Catfish) class. 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 the installation of ASW missile equipment.
Design and construction
The bow sonar installations appear to be similar to those fitted to Soviet nuclear attack submarines. The propulsion plant was the same as the last subgroup of the Foxtrot class. The Tango class had far more battery capacity, far higher than any 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.
Construction of this class has now stopped. The B-380 of the Black Sea Fleet was the last to be decommissioned in 2016 and the scrapping began in Inkerman in 2020.[1]
Service history
By October 2021, the sail of submarine B-380 had been installed, with the assistance of the Russian Maritime Tradition Club Association, at the Mistral Hotel & Spa, Intra district of Moscow.[1]
