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".[2] 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.

Design
editNexter offers two versions of the Narwhal:
- Narwhal 20A, based on the Nexter M621, firing 20×102mm ammunition;[3]
- Narwhal 20B, based on the Nexter M693, firing 20×139mm ammunition. This is the version operated by the French Navy.[4]
The turret houses electro-optical cameras that offer daylight and nighttime vision, as well as a motion tracking system. It can rotate 360° in azimuth, and from +75° to -20° in elevation.[5] The gun is stabilised and can rotate quickly to attack targets at close range.[4]

The French Navy uses the Narwhal on a number of ships. On large units, it is used as a secondary armament for self-defence, while it can constitute the main armament of smaller units.
As secondary armament
editAlthough the FREMM class frigates were designed from inception to use the Narwhal, the first units of the series, such as Aquitaine, were not initially fitted with the weapon. The first FREMM to be fitted with Narwhal immediately after construction was Normandie in 2013,[6][7] before being renamed to Tahya Misr and transferred to Egypt in 2015, without ever being commissioned in the French Navy.[8] The following ship, Provence, as well as all subsequent units, were also equipped with Narwhal at fitting out. The Narwhal on FREMMs are interfaced with the Herakles radar through the combat information system, minimising reaction time when attacking targets.[3]
Mistral class helicopter carriers received the system during their refit in 2016 for Dixmude (L9015),[9] in 2017 for Tonnerre (L9014)[10] and in 2018 for Mistral (L9013).[11]
Aircraft carrier Charles De Gaulle mounted three Narwhal during a refit in 2019 to counter asymmetric threats. Although she had been modified to accommodate the weapon during her mid-lift refit from 2017 to 2018, budgetary reasons had prevented installation at the time.[12]
Air defence frigates of the Horizon class carry three Narwhal to replace the original manually operated 20 mm F2 autocannons. Replacement took place in 2018 on Forbin[11] and in 2019 on Chevalier Paul.[13]
Narwhal is also due to equip the upcoming frégates de défense et d’intervention.
As main armament
edit
Narwhal constitutes the main armament of the three Confiance-class patrol boats, commissioned from 2016. Confiance was the first French patrol boat to mount the system. The fire control system of Narwhal is designed to guarantee that warning shots land safely off-target.[14]
The project for Patrouilleur Outre-mer patrol vessels, unveiled in January 2020, also comprised a Narwhal gun as main armament at the bow of the ship.[15]
