World War II

Following shakedown, Pickens steamed west, engaged in amphibious training in Hawaiian waters, and on 27 January 1945, got underway for the western Pacific Ocean with elements of the 4th Marine Division embarked. A unit of TransDiv 45, she arrived off Iwo Jima on the morning of 19 February. Despite cold weather and high seas, she stood off the assault beach, 0730–1800, to land 2nd Battalion 25th Marines and their assigned Shore Party D Co. 133 Naval Construction Battalion. Retiring at night, she returned daily to continue offloading cargo and to take on casualties. On 28 February 1945, she got underway for Saipan, thence to Guam to disembark her casualty passengers.

For the next month Pickens, with 2nd Division Marines embarked, rehearsed for Operation Iceberg. On 27 March 1945, she departed the Marianas and on 1 April participated in the diversionary landings on Okinawa’s southeastern coast, during which she assumed duties of Division Commander (TransDiv 44) after USS Hinsdale (APA-120) was kamikazed. She effected the rescue of survivors from that APA, LST-884, and LST-724. On 2 April, she repeated the feint, then swung around to the stand-by area where she remained until 9 April. Pickens then returned to Saipan, and on 14 April debarked her troops.

On 4 June 1945, Pickens sailed for Noumea, whence she carried cargo back to the Marianas before heading back to California and availability. Arriving at San Francisco, California, 3 August, she completed availability after the end of the war and at the end of the month joined others of her type in carrying occupation troops to the Far East and bringing back veterans. She completed “Operation Magic Carpet" duty at San Francisco 7 January 1946, then got underway for the U.S. East Coast and inactivation.
