The Soviet Navy's Project 611 (NATO reporting name: Zulu class) were one of the first Soviet post-Second-World-War attack submarines. They were similarly capable to 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 World War II Type XXI U-boat.^[1]
