"Yellowstone" performed faithful service to the Fleet for the next 28 years, providing repair, supply, and auxiliary services (i.e., power and fresh water) not only to destroyers (the purpose for which she was designed) but also to aircraft carriers and submarines.In time, this valuable adjunct to the fleet earned a reputation for reliability and dependability that caused some to nickname her "Old Faithful," after the famous geyser in Yellowstone National Park.
