DAMEN Naval and Rolls-Royce business unit Power Systems have signed a contract for the delivery of 16 mtu diesel generator sets for the four new F126 Frigates for the German Navy. The agreement also includes an Integrated Logistics Support (ILS) package. 

This is the first time a contract has been awarded for mtu naval diesel generator sets. According to Managing Director of DAMEN Naval, Hein van Ameijden, the choice was based on Rolls-Royce’s high-end naval-oriented mtu solutions and experience on the high-end naval market: “We are delighted to announce the news of this contract and the fact we have found another German partner for this prestigious and important project for the Bundeswehr. We look forward to working with Rolls-Royce and its mtu solutions again.”

The onboard power of each F126 vessel will be provided by four mtu Series 4000 variable speed gensets. According to Rolls-Royce, these high performance gensets are the most environmentally friendly naval gensets the company has ever produced: They meet the requirements of the IMO III emissions directive thanks to state-of-the-art mtu Selective Catalytic Reduction (SCR) systems. Due to their variable speed capability, the engines can be operated efficiently, saving fuel and reducing maintenance.


“We are extremely proud to once again be chosen by DAMEN Naval as partner in this very important and prestigious project,” said Paul Röck, Director Sales Governmental at Rolls-Royce business unit Power Systems. “Our advanced sustainable solutions for both power and control of the F126 vessels will play a key role in ensuring the frigates’ reliability, efficiency, and operational success.”

“The biggest advantage of the variable speed generator set is reduction of fuel consumption at part load operation,” added van Ameijden. “For DAMEN Naval it is the first time that variable speed generator sets are applied on Naval vessels in combination with a DC Grid. We expect that this type of configuration will be the new standard in high-end naval applications.”

With this contract, Rolls-Royce continues its decades-long cooperation with the German Navy. Vessels such as the predecessor frigate classes F124 and F125 as well as the corvettes K130 are equipped with mtu engines and diesel generator sets from Rolls-Royce. The diesel generator sets will provide electrical power to the F126’s combined diesel electric and diesel (CODLAD) propulsion system. The CODLAD propulsion system provides a top speed of more than 26 knots. The first diesel generator sets will be delivered early 2024 to the yard.

In June 2020, the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) awarded the construction contract for the four F126 frigates to Dutch shipbuilder DAMEN as the general contractor with its sub-contractors Blohm+Voss and Thales. The ships will be constructed entirely in Germany at shipyards in Wolgast, Kiel and Hamburg. The first ship will be handed over in Hamburg in 2028.
