Fairbanks Morse Defense has received a US Navy contract to supply an FM 175D high-speed diesel generator engine for integration into the DDG(X) land-based propulsion system test site.
The engine will support risk reduction efforts in the development of the next-generation destroyer.
“The selection of the FM 175D for this important land-based test highlights the superior power density needed on modern surface combatants, ensuring the DDG(X) has the energy needed to operate advanced combat systems while maintaining operational efficiency,” said Mike Clark, Chief Operating Officer of Fairbanks Morse Defense.
DDG(X), the US Navy’s next-generation large surface combatant, is in the design and feasibility phase, with construction planned for 2032.
It will replace Flight II Ticonderoga-class cruisers and Flight I/II Arleigh Burke-class destroyers.
The ship will utilize an Integrated Power System, expected to generate over 75 megawatts (100,530 horsepower), to support advanced sensors, high-energy systems, and upgraded propulsion.
Features
The FM 175D, introduced in the US in 2023, is built for applications requiring high power density.
It supports both mechanical propulsion and onboard power generation.
Its compact size makes it suitable for integration into naval platforms with strict space, weight, and fuel use constraints.
The FM 175D generator set delivers up to 3.8 megawatts of power (5,096 horsepower), with a power output range of 1,740 to 4,400 kilowatts (2,333 to 5,900 horsepower).
It operates at speeds ranging from 1,800 to 2,000 revolutions per minute.
The engine is available in 12-, 16-, or 20-cylinder configurations, with a cylinder bore of 175 millimeters (6.9 inches).
