The squadron continued attacking urban areas with incendiary raids until the end of the war in August 1945, attacking major Japanese cities, causing massive destruction of urbanized areas. Also conducted raids against strategic objectives, bombing aircraft factories, chemical plants, oil refineries, and other targets in Japan. The squadron flew its last combat missions on 14 August when hostilities ended. Afterwards, its B-29s carried relief supplies to Allied prisoner of war camps in Japan and Manchuria.
The squadron remained in the Western Pacific, assigned to Twentieth Air Force. It moved to Clark Field in the Philippines in March 1946. It was inactivated at Clark on 15 June 1946. Its low-hour aircraft were flown to storage depots in the United States.
