The BPF was tasked to attack Japanese airfields in the Sakishima Islands and Formosa before and during the early stages of the invasion of Okinawa. "Unicorn" was primarily engaged in preparing aircraft for issue to the operational squadrons aboard the fleet carriers during this time, rather than repair them, but she did repair, modify or service 105 aircraft in March–May 1945. The ship sailed for Australia on 22 May and arrived in Sydney on 1 June. She sailed for Brisbane on 6 June to have her bottom cleaned at the Cairncross Dockyard and to load more replacement aircraft. "Unicorn" arrived at Manus on 22 July to prepare for operations off Japan. She was still there when Japan surrendered on 15 August. The ship began to ferry aircraft, equipment and men back to Australia after the surrender, a task which ended on 6 November, when she arrived at Sydney. "Unicorn" departed for home in December 1945 and arrived in Plymouth in January 1946. She was decommissioned and placed in reserve.
