The US Navy has taken delivery of the fifth John Lewis-class replenishment oiler, USNS Lucy Stone (T-AO 209), following its handover by General Dynamics NASSCO. The transfer comes after the vessel successfully completed a series of rigorous sea trials and component assessments, confirming its readiness for operational service.
The delivery is part of the Navy’s long-term T-AO recapitalization effort, which focuses on replacing aging logistics ships with modern tankers capable of supporting surface combatants and embarked helicopters. These vessels play a critical role in sustaining naval operations by delivering fuel and dry stores across the fleet’s global areas of responsibility.
Washington plans to field a total of 20 John Lewis-class oilers, significantly strengthening the Navy’s maritime logistics backbone. Currently, four ships are operational, while six more are progressing through construction and outfitting phases, reflecting the steady momentum of the program.
Designed for high-capacity replenishment, the USNS Lucy Stone is 227 meters long and features five refueling stations and two dry cargo handling systems. The ship can carry 162,000 barrels of fuel, accommodate 125 sailors, and support helicopter operations for vertical replenishment missions.
The vessel is powered by dual Fairbanks-Morse diesel engines, enabling a top speed of 20 knots and a range of over 11,000 kilometers. To enhance survivability in contested environments, the ship is fitted with torpedo defense systems, crew-served weapons, automated gun systems, and surface-to-air missiles.
