SSG 651 Juliett

The Project 651, known in the West by its NATO reporting name Juliett class, was a class of Soviet diesel-electric submarines armed with cruise missiles. They were designed in the late 1950s to provide the Soviet Navy with a nuclear strike capability against targets along the east coast of the United States and enemy combatants (aircraft carriers).

The head of the design team was Abram Samuilovich Kassatsier. They carried four nuclear-capable cruise missiles with a range of approximately 300 miles, which could be launched while the submarine was surfaced and moving less than four knots (7 km/h). Once surfaced, the first missile could be launched in about five minutes; subsequent missiles would follow within about ten seconds each.
