The Kortik (Russian: Кортик, "dirk") close-in weapon system (CIWS) is a modern naval air defence gun-missile system deployed by the Russian Navy. Its export version is known as Kashtan (Russian: Каштан, English: Chestnut), with the NATO designation CADS-N-1 Kashtan.[8]
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.[9]
