USS Isle Royale (AD-29) was a Shenandoah-class destroyer tender named for an island of the Great Lakes. Isle Royale was launched by Todd Pacific Shipyards, Inc. of Seattle, Washington on 19 September 1945; sponsored by Mrs. Greer A. Duncan; and delivered to the Navy on 2 July 1946 for layup in the San Diego Reserve Fleet. During her period of inactivation, Isle Royale served as headquarters ship for the San Diego Subgroup, Pacific Reserve Fleet. She was designated to replace the USS Hamul (AD-20) in the active fleet, and commissioned at Long Beach, California on 9 June 1962, taking Hamul's officers and men as that ship decommissioned. After shakedown, Isle Royale moved to Long Beach to begin her services to Pacific Fleet destroyers, supplying them with parts and vital repair facilities.
