Project 671RT "Sjomga" (Сёмга, Russian for salmon ) was the name of a series of Soviet nuclear submarines during the Cold War , which NATO designated as the Victor II class . These nuclear powered fighter submarines ( SSN ) were first put into service by the Soviet Navy in 1972.

Development and construction

The two pressurized water reactors of the OK-300 type were retained , but the diesel generators were increased to 460 kW each. The submarines had to be extended for the new generators, additional crew members and larger torpedo rooms. Two electric motors, each with an output of 275 hp, functioned as a reserve or emergency drive, which could operate two small propellers that were arranged parallel to the propeller of the main drive. Like their predecessors, the boats of the Victor II class were designed as double-hulled boats and had a similar hull shape, which, however, was composed for the first time from prefabricated modules, which shortened the construction time.

Project 671RT, 1986

The armament was reinforced, so that in addition to four 533-mm torpedo tubes , two 650-mm torpedo tubes were planned. Since the 650 mm torpedoes were also significantly longer than their 533 mm predecessors, the torpedo bearing had to be enlarged so that it protruded further into the ship's interior. This made a new planning of the entire first section of the submarine necessary. Only the upper part of the torpedo store was lengthened aft , so that the longer torpedoes could only be accommodated there and their stock could never be more than six pieces (four in the upper part of the store and two more in the tubes). The smaller torpedoes were housed below, above and next to the storage benches for the 650 mm weapons, so that a maximum of 18 of them were available (four each in the storage racks on starboard and port , three each in the two middle bearings and four more in the pipes). In addition to conventional 533 mm and 650 mm torpedoes, all boats were also able to fire RPK-2 “Vjuga” (Вьюга, Russian for snowstorm) missiles equipped with nuclear or conventional warheads through the torpedo tubes while submerged.

On the K-378 , two five- blade propellers were arranged one behind the other in a tandem for the first time .

After only seven boats of the class were put into service, production was suddenly stopped. Western experts suspect intelligence that the KGB had obtained from the spy ring surrounding the American naval member John A. Walker as the reason . This information evidently gave the impression that the previous submarine designs of the Soviet Union were so easy for NATO to locate that they were hardly of any tactical value.

All boats were decommissioned in the 1990s and are now being scrapped , partly financed by the G8 countries and neighboring countries . The boats are divided into three sections. While bow and stern sections can be scrapped, the reactor section must be safely stored for years before dismantling can begin.

Calls

The boats of the Victor II class belonged to the Soviet Northern Fleet and were mostly assigned to the 24th U-Boot Division . Their patrols were mainly limited to the North Sea.

K-513 was in 1981 in the sea areas around the Persian Gulf, visited Mozambique , Yemen , Ethiopia and 1982 the friendly Angola .
