'''Project 651''', known in the West by its [[NATO reporting name]] '''Juliett class''', was a class of Soviet [[Submarine#Diesel–electric_transmission|diesel-electric]] [[cruise-missile submarine]]s. 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 missile]]s with a range of approximately {{convert|300|nmi|km}}, which could be launched while the submarine was surfaced and moving less than {{convert|4|kn|km/h|spell=in}}. Once surfaced, the first missile could be launched in about five minutes; subsequent missiles would follow within about ten seconds each. Initially, the missiles were the inertially-guided P-5 ([[NATO reporting name]] [[SS-N-3]]c Shaddock). When [[submarine-launched ballistic missile]]s rendered the P-5s obsolescent, they were replaced with the P-6 (also [[NATO reporting name]] [[SS-N-3]]a Shaddock, though a very different missile) designed to attack aircraft carriers. A special 10&nbsp;m<sup>2</sup> target guidance radar was built into the forward edge of the sail structure, which opened by rotating. One boat was eventually fitted with the Kasatka satellite downlink for targeting information to support P-500 4K-80 "Bazalt" ([[P-500 Bazalt|SS-N-12 Sandbox]]) anti-ship cruise missiles. The Juliett class had a low magnetic signature [[Austenite|austenitic]] steel double hull, covered by {{convert|2|in|mm|spell=in}} thick black tiles made of sound-absorbing hard rubber.
