John Lewis-class replenishment oiler

The John Lewis-class ships are double-hulled and constructed to commercial standards and OPNAVINST 9070.1 requirements. They are classed to American Bureau of Shipping steel vessel rules.^[3] The ships have capabilities similar to the Henry J. Kaiser-class replenishment oilers and rely on existing technology.^[4] The ships can carry 156,000 barrels of oil and have increased dry cargo storage over the Henry J. Kaiser class.^[5]

There are stations on both sides of each ship for underway replenishment of fuel and stores, and will have two dry cargo transfer rigs. The John Lewis-class ships have self-defenses against mines and torpedoes, and are equipped with crew-served weapons which are operated by embarked Navy Expeditionary Security Teams for limited self-defense ability against small boat attack.^[4]

The ships have space, weight, and power reserved for additional self-defense systems, including close-in weapon systems (CIWS) or SeaRAM, and an anti-torpedo torpedo defense system. Even with additional self-defense systems installed the ships will still require escort if operating in a higher threat environment.^[4]

In June 2016, General Dynamics National Steel and Shipbuilding Company (NASSCO) was awarded a design and construction contract for six John Lewis-class replenishment oilers.^[6] NASSCO began construction on John Lewis in September 2018, and began construction on Harvey Milk in September 2020.^[7] In January 2020 the lead ship delivery estimate was delayed from November 2020 until June 2021, due to delays in delivery of gear and flooding of a graving dock.^[4] In September of 2024, General Dynamics was awarded a contract for eight additional John Lewis-class ships, to be delivered by January of 2035.^[8]

The class is named for its lead ship, John Lewis, which is named for American civil rights movement leader and politician John Lewis. The remaining John Lewis-class oilers will be named after prominent civil rights leaders and activists.^[4] In 2025, the former Harvey Milk was renamed after Medal of Honor recipient Oscar V. Peterson. According to Secretary of Defense Pete Hegseth, the action was to help the Navy align with the priorities of President Trump and to, "reestablish the warrior culture." The Navy clarified that no other ships in the class would be renamed.^[9][10]
