The P-5 "Pyatyorka" (Russian: П-5 «Пятёрка»; "Pyatyorka", "fiver" in English), also known by the NATO codename SS-N-3C Shaddock, was a Cold War era turbojet-powered cruise missile of the Soviet Union, designed by the Chelomey design bureau. The missile entered service in 1959. Pyatyorka is a common name for the missile as the "digit 5", corresponding to the R-7 Semyorka, the digit 7.
The basic version of the missile was an inertially-guided submarine-launched cruise missile to threaten the US coast. The missile could be armed with either a 1000 kg high explosive or a 200 or 350 kt nuclear warhead. It had a speed of about 0.9 Mach, range of 500 km and CEP of about 3000 m. The later variant had a range of possibly up to 1000 km. The first missiles were installed in Project 644, Whiskey Twin Cylinder and Project 665, Whiskey Long Bin submarines.
Versions of P-5 were later developed equipped with radar homing to be used as anti-ship missiles. The last anti-ship versions were retired from active service about 1990, replaced by the P-500 Bazalt and P-700 Granit.
There were actually three versions of turbojet-powered, cruise missiles that were called "SS-N-3" by Western intelligence sources, with multiple variants. The earliest, P-5 was called SS-N-3c, and later versions SS-N-3a and SS-N-3b. The various Russian designations are believed to be P-5 "Pyatyorka", P-6, P-7, and P-35 Progress. Some sources indicate that missiles 'P-10' and 'P-25' may also exist.
NATO called the submarine-launched radar-homing versions of the P-6 SS-N-3A 'Shaddock'. These were carried by Echo II and Juliett class submarines for targeting US aircraft carriers. Russian sources indicate that there was only submarine-launched version of P-5. The surface-launched, radar-homing version called P-35 was used by Kynda and Kresta I class guided-missile cruisers. The P-7 was possibly a longer-ranged version of the P-5, or a further development of the P-6.
There were also land-based versions of these missiles transported in and launched from an eight-wheel truck (ZIL-135KM).
Yugoslavia deployed the SS-N-3 as a ground-sea system.

The Lake Inari Incident
On 28 December 1984 a SS-N-3 missile used as a target by the Soviet Navy strayed over Finnish border and crashed into Lake Inari. This was a modified version fitted with avionics taken from MiG for remote control. The likely cause was loss of radio contact between the operator and the missile.
