General Dynamics NASSCO has secured a $1.7-billion contract to build two more John Lewis-class fleet replenishment oilers (T-AO 215 and T-AO 216) for the US Navy, strengthening the service’s ability to sustain ships at sea. The deal is part of a broader procurement effort that could see up to eight new vessels added to the class. So far, four ships have already been delivered from NASSCO’s San Diego yard, which remains the Navy’s primary center for auxiliary ship construction. The John Lewis-class represents the Navy’s newest generation of fuel and supply vessels operated by the Military Sealift Command. These oilers are essential to supporting global naval operations—refueling carrier strike groups and surface warships with diesel, jet fuel, and limited dry cargo while underway, enabling prolonged deployments without port calls. Each vessel measures 742 feet (226 meters) in length, displaces nearly 50,000 tons, and can carry 162,000 barrels of fuel. Designed for efficiency and endurance, the ships achieve 20 knots (37 km/h) and are manned by 129 civilian mariners. Their five replenishment stations allow multiple vessels to refuel simultaneously, improving tempo and mission readiness. Work on the class began with a $3.2-billion design and construction contract awarded in 2016. Subsequent orders in 2022 and 2024 have extended production to meet growing logistical needs. Beyond expanding operational capacity, the award ensures long-term employment at NASSCO’s San Diego facility and sustains a domestic supply chain vital to the Navy’s auxiliary fleet programs. It also continues the Navy’s emphasis on industrial stability—maintaining skilled labor, standardizing production, and reducing per-unit costs through serial construction. Once delivered, the new oilers will join a fleet that underpins US sea power projection by keeping warships fueled, stocked, and ready for sustained operations—an increasingly critical requirement in a time of extended global naval commitments.
