Project 611 B-62 "Vega" - 31.12.53 built

The Soviet Navy's Project 611 (NATO reporting name: Zulu class) were one of the first Soviet post-war attack submarines. They were roughly as capable as the American GUPPY fleet-boat conversions. They were a contemporary of the Whiskey-class submarines and shared a similar sonar arrangement. Like most conventional submarines designed 1946-1960, their design was influenced by the German Type XXI U-boat of the World War II era.
Twenty-six boats were built overall, entering service from 1952 to 1957
