Takanis Bay is a small bay on the southwest coast of Yakobi Island, in the Alexander Archipelago of Alaska. Kaiser at Vancouver laid her down on 16 December 1943 as Maritime Commission hull 1126 and launched her on 10 March 1944. Mrs. Alden R. Sanborn sponsored her. Captain A. R. Brady commissioned her on 15 April 1944.
After shakedown she operated out of San Diego with Fleet Air, West Coast, through the middle of August 1945. She tested pilots for carrier operations. Between 24 May 1944 and 28 August 1945 she qualified 2,509 of them.
On 28 August she sailed for Hawaii and joined the Carrier Transport Squadron, Pacific. Two trips brought 1,300 servicemen back to San Diego. Late in September, bunks for 800 passengers were installed, and she made two more round trips to Hawaii and one to the Tokyo Bay area. She reached San Pedro from the last voyage on 2 January 1946, moved to Puget Sound in April, and was decommissioned on 1 May 1946. She was redesignated CVU-89 on 12 June 1955, struck on 1 August 1959, and sold on 29 June 1960 to Hyman-Michaels Company of Chicago for scrap.
