The squadron began combat missions over Japan on 25 February 1945 with a firebombing mission over Northeast Tokyo. The squadron continued to participate in wide area firebombing attack, but the first ten-day blitz resulting in the Army Air Forces running out of incendiary bombs. Until then the squadron flew conventional strategic bombing missions using high explosive bombs.
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.
Squadron remained in Western Pacific, although largely demobilized in the fall of 1945. Some aircraft scrapped on Tinian; others flown to storage depots in the United States. Inactivated as part of Army Service forces at the end of 1945.
