Damen Naval has selected German technology group Rheinmetall to supply eight state-of-the-art MLG27-4.0 defence systems for the F126 frigates the shipyard is building for the German Navy. Each frigate will be equipped with two MLG27-4.0 systems. The contract includes an option for further MLG27-4.0 systems for two additional vessels. The 27mm cal. MLG27 4.0 light naval gun is a member of the new SeaSnake RCWS family of products made by Rheinmetall Waffe Munition GmbH of Unterlüß, Germany, a Group subsidiary with multiple locations. The core element of the remotely controlled MLG27 4.0 is the BK-27M revolver gun. In use throughout the German Navy, the predecessor of the new MLG27 4.0 serves as secondary armament on Germany’s current F125 frigates.Compared to previous models, the next-generation MLG27-4.0 defence system features a series of technological innovations. It is a highly advanced ship defence system equipped with daylight cameras, infrared sensors and laser rangefinders, and can be integrated into an existing shipboard command system, taking full account of all applicable IT and OT security requirements. Moreover, its new, fully digital system architecture enables direct impact on external target coordinates in standard WGS-84 format. The 27mm cal. revolver gun can operate in single-shot mode, in adjustable bursts, or at a sustained rate fire of up to 1,700 rounds per minute. Its low weight and adjustable grid-firing capability, coupled with an integrated simultaneous tracker, make the MLG27-4.0 weapon system a powerful armament for modern frigates such as the F126 class.In combination with other weapon systems envisaged by Damen Naval for the project, the F126 frigates will feature a comprehensive, highly effective array of armament that delivers a critical tactical edge against a multitude of threats.
