The USNS Rappahannock is a Henry J. Kaiser-class underway replenishment oiler operated by the Military Sealift Command to support United States Navy vessels. As the eighteenth and final ship of her class, she was constructed at Avondale Shipyard in New Orleans, Louisiana, with her keel laid on March 29, 1992, and launched on January 14, 1995. Notably, Rappahannock is one of only three ships in her class built with a double bottom hull, a design feature mandated by the Oil Pollution Act of 1990. This structural modification results in a hull separation of 6 feet at the sides and 6 feet 6 inches on the bottom, reducing her liquid cargo capacity by approximately 21,000 barrels compared to her sister ships. The vessel entered non-commissioned service under the control of the Military Sealift Command on November 7, 1995, crewed primarily by civilians. Rappahannock primarily operates within the United States Pacific Fleet, providing vital underway replenishment services. Her role includes delivering fuel, supplies, and humanitarian aid, exemplified during Operation Tomodachi when she supplied fuel, bottled water, and relief materials to Japan and South Korea. She has conducted at least ten underway replenishment missions, delivering over 2.4 million gallons of fuel to support naval operations. Rappahannock has also been involved in notable incidents, such as a 2012 encounter in the Persian Gulf off Dubai, where an Indian fishing boat approached aggressively despite warnings. The ship's security team fired upon the vessel with a .50-caliber machine gun, resulting in the death of an Indian fisherman and injuries to three others. Additionally, she participated in a replenishment-at-sea with the USS Boxer in the South China Sea on October 16, 2019. Overall, the USNS Rappahannock plays a crucial logistical role in supporting naval operations across the Pacific and beyond, reflecting her significance as a key element of the U.S. maritime sustainment fleet.
