The sponsor's husband was Captain Whitgrove. The Navy acquired the ship and commissioned her on 18 January 1945. Her captain was Commander J. R. Bagshaw, Jr., USNR.
San Diego was behind her on 5 April 1945. Troops and cargo went ashore during a Pearl Harbor call that lasted from 12 April through the 27th. Men of a construction battalion then rode her to Samar, with arrival on 17 May. Army troops embarked for the next passage. She went by Ulithi to Okinawa and from 24 to 27 June unloaded while aircraft attacked the anchorage. Survivors from ships that had gone down off Okinawa came aboard for the trip to San Francisco.
Upkeep in the United States occupied 17 to 30 July. She returned to Pacific transport duty with passengers and cargo for Guam. Soldiers also went with her from Manila across to Aomori to take up occupation duty in Japan. Magic Carpet work followed, bringing home men who were eligible for discharge. The first of those groups reached San Diego on 21 October. A second Okinawa voyage ended on 8 December. She sailed from Seattle on 12 January 1946 and made Norfolk on 1 February.
On 5 June 1946 the Navy left her commissioned and shifted her into reserve. Out-of-commission reserve status followed on 15 October 1946. On 1 October 1968 the Maritime Commission took her to be disposed of. One battle star was credited for service in the war.
