 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.The weapon is a modular system consisting of a command module and typically two combat modules, as in the case of the two "Sovremennyy"-class destroyers "Taizhou" (ex-"Vnushitelnyy") and "Ningbo" (ex-"Vechnyy") in Chinese service, although the number can be as many as 8 in the case of "Admiral Kuznetsov".The command module detects and tracks threats, distributes targeting data to the combat modules, and interrogates IFF of approaching threats.
