The Cimarron-class was a class of five replenishment oilers which served in the United States Navy between 1981 and 1999. These ships were sized to provide two complete refuelings of a fossil-fueled aircraft carrier and six to eight accompanying destroyers. All five of the class were jumboized in 1990-92 by being cut in two and a 108-foot (35.7 m) section inserted, increasing their capacities from 120,000 bbls to 180,000 bbls, adding capacity for 300 tons of munitions and improving underway replenishment capabilities.
