After shakedown LST-1083 departed 22 March for the Panama Canal and Guam, where she picked up troops and supplies and transported them to Saipan and Okinawa. On V-J Day she was back at Guam, and loaded troops of the 4th Marines for Tokyo Bay.

After a period on the west coast, LST-1083 returned to Korea 22 March 1952 to resupply islands off the northwestern Korean Coast and pick up Prisoners of War. She returned to the United States in December, but departed again for Korea in September 1953 for further supply lifts, returning to San Diego in July 1954.
