The Nexter Narwhal is a type of remotely operated naval artillery turret made by the French company Nexter. It houses a 20 mm autocannon based on the Nexter M621 and M693. The name "Narwhal" is a backronym of "NAval Remote Weapon, Highly Accurate, Lightweight". It is designed to fit warships of all types ranging from patrol boats to frigates to aircraft carriers, notably as a close-quarters self-defence weapon.
