RENK will supply a propulsion system and gearboxes for the German frigate F126

Damen Naval signed a Contract with Augsburg-based propulsion specialist RENK to supply gearboxes and electric propulsion systems for the German Navy’s four future F126 frigates.

RENK’s new combined diesel-electric and diesel (CODLAD) propulsion system will provide a speed of up to 26 km.

Gearboxes will be used to connect each diesel engine to the driveshaft.

Besides the gearbox and the propulsion system, RENK will supply advanced electric drives (AED).

The second generation AED will drive the propellers either individually or together with the diesel engine.

According to Damen Naval, this is the first time that German Navy frigates will use this propulsion concept.

With the new CODLAD configuration, the propulsion systems will offer noise reduction through smooth elastic bearings, increased power density, flexible couplings as well as reduced weight and installation height.

In a press release, Damen Naval said: “The upgradeable second stage of the AED will now be installed on the F126 frigates.

“RENK has optimized significant aspects of the drive system for naval applications. As a result, the design meets the low noise levels specified by the German Navy.

“This makes new frigates difficult to detect, especially in the lower speed range covered by AED.”

In 2020, the Federal Office for Equipment, Information Technology and In-Service Support of the Bundeswehr (BAAINBw) selected Damen Naval as general contractor for the construction of four F126 frigates.

The program also involves two subcontractors, Blohm+Voss and Thales.

Additionally, the contract includes an additional option for two additional frigates.

The construction of approximately 166 m long F126 or MKS 180 multipurpose combat ships will take place at the Wolgast, Kiel and Hamburg shipyards in Germany.

The delivery of the first frigate to the German Navy is scheduled for 2028 in Hamburg.
