SAN DIEGO — May 14, 2026 : General Dynamics NASSCO has received $856 million in U.S. Navy funding for the construction of T-AO 217, the latest vessel in the John Lewis-class fleet replenishment oiler programme. The funding, announced on May 13, 2026, supports the Navy’s continuing effort to modernise its replenishment fleet and strengthen long-range naval logistics capabilities.
The allocation forms part of an eight-ship block-buy contract awarded to NASSCO in September 2024 covering vessels T-AO 214 through T-AO 221. T-AO 217 will be built at the company’s San Diego shipyard, where multiple vessels in the class are already under construction.
The John Lewis-class oilers are designed to support the Military Sealift Command by providing fuel, dry cargo and aviation logistics support to deployed naval forces. The ships enable carrier strike groups, amphibious ready groups and surface combatants to remain at sea for extended periods without returning to port, improving operational endurance and fleet sustainment during long-range deployments.
The class is gradually replacing the ageing Henry J. Kaiser-class replenishment oiler vessels that have been in service since the 1980s. Compared with the earlier ships, the new oilers incorporate double-hull construction, upgraded automation systems, modernised cargo handling equipment and reduced crew requirements intended to improve efficiency and lower operating costs.
Each John Lewis-class vessel measures approximately 742 feet (226 metres) in length with a beam of 106.5 feet and a full-load displacement of around 49,850 tons. Powered by two Fairbanks-Morse medium-speed diesel engines, the ships can reach speeds of up to 20 knots while carrying approximately 162,000 barrels of fuel alongside dry cargo and aviation support supplies.
The vessels are equipped for connected underway replenishment operations through multiple fueling stations and cargo transfer rigs. The class also features an enlarged helicopter flight deck to support vertical replenishment missions during deployed operations.
In addition to logistics capabilities, the ships incorporate defensive systems including the AN/SLQ-25A Nixie torpedo countermeasure system and crew-served defensive weapons operated by embarked Navy security teams. The design also reserves space, electrical capacity and weight allowances for potential future installation of close-in defensive systems such as Phalanx CIWS or SeaRAM.
According to the Department of the Navy, the multi-ship procurement approach used for the programme is expected to save approximately $491 million compared with annual procurement methods. Multi-ship contracts are also intended to maintain stable production activity within the U.S. shipbuilding industrial base and preserve skilled labour at key naval shipyards.
NASSCO is currently under contract to construct 17 of the Navy’s planned 20 John Lewis-class oilers. The company has delivered five vessels to date, while five additional ships remain under construction at the San Diego facility.
The programme began with an initial 2016 contract covering the first six ships and was later expanded in 2022 to include T-AO 211 through T-AO 213 before the 2024 block-buy agreement covering T-AO 214 through T-AO 221.
Dave Carver, president of General Dynamics NASSCO, stated that the John Lewis-class programme represents the company’s longest-running Navy production series. He said the funding for T-AO 217 helps maintain workforce stability, sustain production continuity and reduce the risk of future layoffs as construction progresses on the remaining vessels in the programme.
The continued production of the John Lewis-class fleet supports the U.S. Navy’s long-term maritime logistics strategy, particularly for sustained operations across contested maritime regions where access to fixed port infrastructure may be limited during future conflicts.
