The XXI Bomber Command was assigned the task of destroying the aircraft industry of Japan in a series of high-altitude, daylight precision attacks
In late October and early November 1944, a series of tactical raids were carried out as training exercises for the crews. From Saipan, the groups of the 73d Bomb Wing flew several bombing missions against Truk to gain combat experience. Aware that there was now a new threat, Japanese aircraft based on Iwo Jima

staged a low-level raid on Isely Field on 2 November, damaging several B-29s on the ground. Retaliatory strikes were ordered on Iwo Jima on 5 and 11 November.
In November 1944, the groups of the 73rd began bombing Japan, with only moderate success. Poor weather, the lack of precision radar bombing equipment, and tremendous winds encountered at high altitudes over Japan made accuracy difficult. The initial raids against Japan had taken place at high altitudes in order to stay above anti-aircraft fire and the effective altitude of defending fighters. Tactics were changed and high-altitude, daylight attacks be phased out and replaced by low-altitude, high-intensity incendiary raids at nighttime. The aircraft would attack individually, which meant that no assembly over the base at the start of the mission or along the way would be needed.
Consequently, it turned to devastating low altitude incendiary attacks. The Division continued attacking urban areas until the end of the war in August 1945, its subordinate units conducted raids against strategic objectives, bombing aircraft factories, chemical plants, oil refineries, and other targets in Japan. The wing flew its last combat missions on 14 August when hostilities ended. Afterwards, the wing's B 29s carried relief supplies to Allied prisoner of war camps in Japan and Manchuria.
The 73d and its subordinate units demobilized rapidly after V-J Day, and the wing's four bomb groups were all returned to the United States, with their B-29s either being flown to Clark Field
