Underway replenishment oiler


The underway replenishment oiler is a type of ship of the United States Navy. These oilers provide underway replenishment of fuel to US Navy ships at sea and jet fuel for aircraft assigned to aircraft carriers. In the British Royal Fleet Auxiliary (naval auxiliary service), such vessels are known as fleet tankers.

Current US Navy replenishment oilers are ships of the Henry J. Kaiser class. Although they are planned to be replaced by the John Lewis-class oiler.
