The US Navy’s LPD 17 Flight II Class amphibious transport dock ships will have improved main propulsion diesel engine (MPDE) efficiency thanks to the installation of a common rail fuel injection system on the ship's Pielstick-Colt 2.5V sequentially turbocharged engine.

The future USS Richard M McCool Jr (LPD 29), being built at Huntington Ingalls Industries Shipyard in Pascagoula, Mississippi, will be the first to receive common rail fuel injection MPDEs.

The system replaces the existing mechanical fuel delivery system and is expected to reduce fuel usage and maintenance costs.

The project began in 2015. Fairbanks Morse engineers collaborated with MAN Diesel and the Naval Surface Warfare Center Philadelphia Division to develop the prototype, which was tested on a future USS Fort Lauderdale engine.

After completion of testing, the common rail fuel injection components were removed and the mechanical fuel injection components were re-installed and retested prior to shipment. Prototype testing on the factory engines demonstrated fuel savings across the navy operating envelope and an emission-reducing engine operating profile was also developed.
