Fairbanks Morse Defense Secures US Navy Contract for Next-Gen DDG(X) Propulsion System Engine

Fairbanks Morse Defense has secured a significant contract with the US Navy to provide an FM 175D high-speed diesel generator engine, intended for integration into the DDG(X) land-based propulsion system test site. This development is part of the Navy’s broader risk reduction initiatives for the next-generation destroyer, aiming to enhance its operational capabilities.

Mike Clark, Chief Operating Officer of Fairbanks Morse Defense, emphasized the importance of this selection, stating that the FM 175D’s advanced power density highlights the requirements for modern surface combatants. This engine will ensure that the DDG(X) has the necessary energy to operate its sophisticated combat systems effectively while maintaining high operational efficiency.

The DDG(X) represents the US Navy’s ambitious plans for a next-generation large surface combatant, currently in the design and feasibility phase, with construction slated for 2032. It is set to replace the aging Flight II Ticonderoga-class cruisers and Flight I/II Arleigh Burke-class destroyers. The new vessel will feature an Integrated Power System capable of generating over 75 megawatts (or 100,530 horsepower), which is crucial for powering advanced sensors, high-energy systems, and enhanced propulsion capabilities.

The FM 175D, which debuted in the US market in 2023, is engineered to meet the demands of high power density applications. It is versatile, supporting both mechanical propulsion and onboard power generation, making it an optimal choice for naval platforms that have stringent requirements regarding space, weight, and fuel efficiency.

Delivering up to 3.8 megawatts of power (5,096 horsepower), the FM 175D can operate across a wide range of outputs from 1,740 to 4,400 kilowatts (2,333 to 5,900 horsepower), while maintaining a speed range of 1,800 to 2,000 revolutions per minute. Additionally, it offers flexible configurations with 12-, 16-, or 20-cylinder options, featuring a cylinder bore of 175 millimeters (6.9 inches).

This contract marks a significant step forward in the development of the DDG(X), reinforcing the Navy’s commitment to integrating advanced technologies into its future surface combatants.
