Fairbanks Morse to Provide Engines for U.S. Navy Replenishment Ship Future USNS Lucy Stone

Fairbanks Morse, a division of EnPro Industries, has been selected to provide the main propulsion diesel engines for the U.S. Navy replenishment oiler, the future USNS Lucy Stone (T-AO-209).

The future USNS Lucy Stone (T-AO-209) is the fifth of the six John Lewis-class replenishment oilers being built for the U.S. Navy by General Dynamics NASSCO at its San Diego facility.

According to the contract awarded, two FM | MAN 12V 48/60 CR engines, rated at around 19,000 bhp each, will be built at the Fairbanks Morse facility in Beloit, Wisconsin and will be delivered to General Dynamics NASSCO in 2022. Fairbanks Morse will also provide auxiliary equipment and commissioning services.

The engines, that are to be delivered, will be equipped with the latest diesel engine technology: a common rail fuel injection system, engine control systems, and will meet the latest emission requirements with an exhaust after-treatment system.

“This partnership will help the US Navy safely and reliably deliver fuel to its global fleet with the best in diesel engine technology,” said Fairbanks Morse President, Deepak Navnith. “The Lucy Stone will rely on Fairbanks Morse engines to complete its missions around the world and move maritime energy forward into the future.”

The construction of future USNS Lucy Stone is part of a $3.2 billion contract awarded by the U.S. Navy to General Dynamics NASSCO for the design and construction of six John Lewis Class Fleet Replenishment Ships. The Navy has also announced plans to procure an additional 14 ships of the John Lewis Class in future contract awards.

John Lewis-Class Replenishment Oilers

John Lewis-class is the U.S. Navy’s newest class of underway replenishment oilers being built by General Dynamics NASSCO shipyard. The vessels of the class are named after prominent civil rights activists and leaders.

The ships are based on commercial design standards and will recapitalize the current T-AO 187 Henry J. Kaiser-class fleet replenishment oilers. These ships are part of the Navy’s Combat Logistics Force and will be operated by the Navy’s Military Sealift Command (MSC).

Designed to transfer fuel to U.S. Navy carrier strike group ships operating at sea, the oilers will feature the capacity to carry 157,000 barrels of oil, a significant dry cargo capacity, aviation capability and a speed of 20 knots.

The John Lewis class will be equipped with a basic self-defense capability, including crew-served weapons, degaussing, and Nixie Torpedo decoys, and has space, weight, and power reservations for Close-In Weapon Systems (CIWS) such as SeaRAMs, and an Anti-Torpedo Torpedo Defense System (ATTDS).

The construction of the first vessel of the class, the future USNS John Lewis (T-AO 205), was started on Sept. 20, 2018, and the keel of the vessel was laid on May 13 this year. The delivery of the ship is planned in late 2020.
