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

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 (

s rendered the P-5s obsolescent, they were replaced with the P-6 (also
NATO reporting name SS-N-3a Shaddock, though a very different missile) designed to attack aircraft carriers. A special 10 m

The Juliett class had a low magnetic signature
austenitic steel double hull, covered by two inch (50 mm) thick black tiles made of sound-absorbing hard rubber. They had exceptionally high reserve buoyancy, and were divided into eight watertight compartments:

# the forward torpedo room
# living accommodations for officers and chiefs and the forward batteries
# the missile control room and batteries
# the control room
# crew berthing and batteries
# the forward engine room containing the diesels and generators
# the aft engine room with the electric motors
# the aft torpedo room.
Initial plans called for 35 submarines of this class. In fact only 16 were actually built, two - including the lead sub, by the Baltic Shipyard,

. They were commissioned between 1963 and 1968, and served through the 1980s. The last one was decommissioned in 1994.
The Juliett class was built due to expected delays in the continued production of the nuclear-powered Project 659 s and 675 s, with six and eight missile launchers, respectively. The Julietts were actually designed after the Echos.
