The R-13 was a submarine-launched ballistic missile (SLBM) developed by the Soviet Union starting around 1955. It was assigned the NATO reporting name SS-N-4 Sark and carried the GRAU index 4K50.
The R-13 was a single-stage liquid-fuel rocket and entered service in 1961. This missile was somewhat similar in design to the R-11FM missile, which caused some confusion in Western intelligence services during the Cold War. The missiles were phased out from 1965 to 1975.
This missile was the first Soviet design to use a small set of rocket engines to perform course and trajectory alterations instead of aerodynamic control surfaces, although a set of four stabilizers were used to keep the missile on-course during initial flight.
During initial testing before the missiles were deployed, 26 of 32 missiles (81%) were successfully launched. While the systems were deployed from 1961 to 1975, 225 of 311 launches (72%) were successful.
