The Kortik is found on the Russian aircraft carrier Admiral Kuznetsov, the Kirov-class battlecruiser, the Neustrashimy-class frigate, as well as the People's Liberation Army Navy Sovremenny-class destroyers, and other modern designs. Typically deployed as a combined gun and missile system, it provides defence against anti-ship missiles, anti-radar missiles and guided bombs. The system can also be employed against fixed- or rotary-wing aircraft or even surface vessels such as fast attack boats or targets on shore.
The Kortik will be replaced in Russian Navy service by the Pantsir-M CIWS, which uses similar rotary cannons but different missile and radar systems.
