The US Navy has awarded General Dynamics NASSCO a $1.7-billion contract to build two additional John Lewis-class fleet replenishment oilers, identified as T-AO 215 and T-AO 216. The deal forms part of a broader Navy initiative to expand its logistics support fleet through a multi-ship acquisition program.
So far, NASSCO has delivered four John Lewis-class vessels, all assembled at its San Diego shipyard, the cornerstone of the company’s shipbuilding operations. The new order follows a 2024 eight-ship contract and a 2022 modification that increased the total number of oilers under production, strengthening the Navy’s long-term supply and refueling capabilities.
The John Lewis-class program began in 2016, when NASSCO received an initial $3.2-billion award to design and build six ships. Operated by the Military Sealift Command, the T-AO oilers provide vital underway replenishment for diesel and jet fuel, along with limited dry cargo, provisions, and potable water, ensuring continuous fleet readiness and sea control.
Each oiler is 742 feet long and 106 feet wide, with a displacement of 49,850 tons and a fuel capacity of 162,000 barrels. Capable of reaching 20 knots, these vessels carry a crew of 129 civilian mariners and feature five replenishment stations. Their endurance and capacity make them indispensable assets in supporting US Navy carrier strike groups and global maritime operations.
