The Kalibr ROC (previously merged with the Biryuza ROC) is a family of Russian cruise missiles, according to the NATO codification SS-N-27 "Sizzler" (from English — "hell" [3], a very hot day[4]). The Novator Design Bureau has been developed and is being produced.

The Kalibr missiles were created on the basis of two projects: the 3M10 strategic nuclear cruise missile with a combat radius of 2500 km developed during the period from 1975 to 1984 at the Novator SMKB and the Alpha anti-ship missile competition (Biryuza ROC).

As of 2019, the Kalibr missile system is in service with the Russian Navy. According to open sources, the maximum firing range of the 3M 14 cruise missile from this complex, flying at subsonic speed, reaches about 2 thousand km
