Following shakedown, ATA–203 departed Texas for Coco Solo, thence with 2 YTBs in tow, she headed for Pearl Harbor, arriving 9 March. Exchanging the YTBs for pontoon barges, the auxiliary tug steamed westward, 16 March, and on 22 May cast off her charges in Nakagusuku Wan, Okinawa. She performed towing jobs in the Okinawa area, then on 11 June, headed south to Leyte.

On 8 September, she got underway for the Japanese home islands, reporting to ComMinDiv 7, off Kyushu, 11 September. Until 29 December she conducted hydrographic surveys off Sasebo, Omura, and Nagasaki, acted as a mine destruction vessel and assisted storm damaged ships. Then detached from all duties in Mine Force, Pacific, she took up towing services for the occupation forces.
On 14 March 1946, ATA–203 headed home, reporting to ComServLant 22 June. Assigned to the 16th (Reserve) Fleet, she decommissioned 20 October 1946 arid was berthed at Orange, Texas.
