John Lewis-class oiler

The John Lewis class is a class of fleet replenishment oilers for the United States Navy's Military Sealift Command, named for its lead ship, which honours the civil rights leader and congressman John Lewis, and intended to total twenty ships. General Dynamics NASSCO was awarded a design and construction contract in June 2016 for six ships, began building John Lewis in September 2018, and in September 2024 won a contract for eight additional ships due by January 2035. The double-hulled ships are built to commercial standards, carry 156,000 barrels of oil and more dry cargo than the Henry J. Kaiser class, and have stations on both sides for underway replenishment. They have defences against mines and torpedoes and reserved space for further self-defence systems. In 2025 the former Harvey Milk was renamed after Medal of Honor recipient Oscar V. Peterson.
