R-27 (missile)

See R27 (airship) for the British rigid airship commissioned in June 1918.

The R-27 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 as fuel and inhibited red fuming nitric acid as oxidizer.

The R-27 missiles were deployed on eg. the Yankee I submarines, including the unlucky K-219.
