Fairbanks Morse contracted to produce engines for Military Sealift Command

BELOIT — Fairbanks Morse Defense (FMD) has been awarded a contract by General Dynamics NASSCO to build and deliver the main propulsion diesel engines for the Military Sealift Command’s future USNS Dolores Huerta (T-AO 214).

“Fairbanks Morse Defense understands that victory at sea begins in the engine room. Over the years, we’ve been honored to work with the military in delivering reliable engines built on proven technology, and we hold that responsibility with the utmost seriousness,” said George Whittier, CEO of Fairbanks Morse Defense. “Our commitment remains steadfast: to equip every ship in the U.S. fleet with the most advanced equipment and technologies, ensuring our sailors can successfully fulfill their mission to protect the freedom of the seas.”

The USNS Dolores Huerta is the 10th vessel in the John Lewis-class of fleet replenishment oilers. It will be powered by two 12V 48/60 CR main propulsion engines and two 71 32/44 CR service diesel engines, all manufactured at FMD’s Beloit, Wisconsin facility. Each engine will feature FMD’s common rail fuel injection system, which improves fuel atomization and combustion efficiency.

Engine delivery for the USNS Dolores Huerta is scheduled for late 2026. Fairbanks Morse Defense has previously supplied engines for T-AO 205 through T-AO 211 and is currently working on engines for T-AO 212 and T-AO 213.

Fairbanks Morse Defense produces engines for military clients including the U.S. Navy and U.S. Coast Guard and has a production facility in Beloit.
