The R-27 Zyb (‹See Tfd›Russian: Р-27 «Зыбь», lit. 'Ripple') was a submarine-launched ballistic missile developed by the Soviet Union and employed by the Soviet Navy from 1968 through 1988. NATO assigned the missile the reporting name SS-N-6 Serb. In the USSR, it was given the GRAU index 4K10. It was a liquid fuel rocket using a hypergolic combination of unsymmetrical dimethylhydrazine (UDMH) as fuel, and nitrogen tetroxide (NTO) as oxidizer.[1] Between 1974 and 1990, 161 missile launches were conducted, with an average success rate of 93%.[2] Total production was 1800 missiles.
The R-27[3] missiles were deployed on the Yankee I submarines, including the K-219.
