Zulu class submarine

The Soviet Navy's Project 611, also known by their NATO reporting name of "Zulu"-class, were designed as attack submarines, but six were converted in 1956 to become the world's first ballistic missile submarines, one armed with a single F-11FM Scud missile and five others with two Scuds each. The missiles were too long to be contained in the boat's hull, and extended into the enlarged sail. Soviet submarine B-67 successfully launched a missile on 16 September 1955.

The design was influenced by the German Type XXI U-boat of the World War II era. [Sean Maloney, 'To Secure Command of the Sea,' University of New Brunswick thesis 1991, p.315]

The success of the converted Zulus prompted the design of Project 629, the Golf class submarines.

A total of 26 boats were built, entering service from 1952 to 1957.
