USNS Yukon (T-AO-202) is a Henry J. Kaiser-class underway replenishment oiler operated by the Military Sealift Command to support ships of the United States Navy.
Yukon, the sixteenth ship of the Henry J. Kaiser class, was laid down at Avondale Shipyard, Inc., at New Orleans, Louisiana, on 13 May 1991 and launched on 6 February 1993. She entered non-commissioned U.S. Navy service under the control of the Military Sealift Command with a primarily civilian crew on 25 March 1994. She serves in the United States Pacific Fleet.
On 27 February 2000, Yukon collided with a smaller civilian cargo ship while entering the port of Dubai in the Persian Gulf.
On 13 July 2000, Yukon collided with amphibious transport dock USS Denver (LPD-9) during an underway replenishment about 180 nautical miles (330 km) west of Hawaii. No one on either ship was injured, and there were no fuel leaks, but Yukon suffered major damage, including several large holes and dents above the water line on her starboard quarter, while a 40-foot (12.2 m) hole was torn in Denver's bow from the second deck to the waterline. The investigation into the accident found Denver responsible. Both ships went to the Pearl Harbor Naval Shipyard at Pearl Harbor, Hawaii, for repairs. Yukon then transited to San Francisco, California, for further repairs at the same time as her scheduled routine overhaul. Yukon returned to service in January 2001.
On 16 May 2012, Yukon collided with USS Essex after Essex suffered an apparent steerage failure upon approach for an underway replenishment. There were no injuries and no loss of fuel was reported. Both vessels were able to continue to San Diego under their own power.
