next generation MLG27-4.0 gun systems for F126 frigates

Gorinchem, Netherlands. 17 November 2022. 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

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.

Tactical advantages against a variety of threats
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. “We are extremely pleased to join forces with Rheinmetall on the F126
project for the German Navy. The broad range of capabilities make their MLG27-4.0 weapon system the
right choice for the F126 frigates,” says Hein van Ameijden, the Managing Director of Damen Naval.
Rheinmetall greatly appreciates its close, trusting relationship with Damen Naval, which, besides
successful cooperation in the F126 project, could lead to follow-up projects. “Our MLG27-4.0 weapon
system and basically the entire SeaSnake family, have proven highly effective against asymmetric
threats. We’re very pleased to be taking part in the ambitious F126 programme and to be supporting
Damen Naval in building the frigates” adds Roman Köhne, managing director of Rheinmetall Waffe
Munition GmbH.

The Dutch shipbuilder Damen Naval, prime contractor for construction of the German Navy’s new F126
frigate generation, will work closely with key subcontractors Blohm+Voss Shipyards GmbH and Thales
Netherlands B.V. in planning and building the four frigates. All four ships will be built entirely at German
shipyards (in Wolgast, Kiel and Hamburg), with the first frigate slated for delivery in 2028. The contract
between Damen and Germany’s Federal Office for Bundeswehr Equipment, Information Technology
and In-Service Support (BAAINBw) includes an option for two more frigates.
