Allegan departed Okinawa on 5 August, bound for Pearl Harbor, Hawaii, via Saipan. She arrived in Hawaiian waters on 26 August, and stood out two days later for San Francisco, California. The vessel reached San Francisco Bay on 5 September and, after a period of voyage repairs, got underway again on 6 October bound for Hampton Roads, Virginia. After retransiting the Panama Canal, Allegan reached Norfolk, Virginia, on 27 October. She was decommissioned at Portsmouth, Virginia, on 15 November 1945; was returned to the War Shipping Administration a week later, and her name was struck from the Navy list on 28 November 1945. She had a very varied history after being released by the Navy. (See second external link below.)
