Pantsir-M is a Russian jamming-resistant naval close-in weapon system (CIWS) which entered service in 2018. Pantsir-M will replace Kashtan-M systems in Russian Navy.

A close-in weapon system is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device.
