502d Bombardment Group

History

Organization and training

The group was organized on 1 June 1944 at Davis-Monthan Field, Arizona. Its operational components, the 402d, 411th and 430th Bombardment Squadrons, were all established squadrons that had briefly activated in other groups as Boeing B-29 Superfortress units, but had been inactivated when B-29 groups were reorganized to consist of only three squadrons. Five days later, the group moved without personnel or equipment to Dalhart Army Air Field, Texas.

Combat in the Pacific and inactivation

The 502d was deployed to the Central Pacific Area in late 1944. Upon arrival the group's personnel were engaged in Quonset hut construction. By mid-July most personnel were able to move into the huts from the initial tents which they were assigned on arrival.

The group arrived at its combat station, Northwest Field, Guam on 12 May 1945. It flew its first combat mission on 30 June, an attack on Rota. It carried out attacks on Truk during July. It flew its first mission against the Japanese Home Islands on 15 July, against the oil refinery at Kudamatsu, and until the end of the war, concentrated on attacks on the Japanese petroleum industry. It was awarded a Distinguished Unit Citation for August 1945 attacks on the coal liquefaction plant at Ube, a tank farm at Amagasaki and the Nippon Oil refinery at Tsuchizaki. After the war it participated in show of force missions and evacuated prisoners of war. The squadron remained on Guam until it was inactivated on 15 April 1946.

Due to a shortage of B-29s, the group was equipped with former II Bomber Command B-17 Flying Fortresses previously used for training heavy bomber replacement personnel. The 502d eventually received Atlanta-built B-29B Superfortresses.

After V-J Day, the 502d flew over Japan to evaluate bombardment damage. In the fall of 1945, the group largely demobilized as part of the "Sunset Project", with some aircraft being sent reclamation on Tinian; others being returned to the United States for storage at aircraft depots in the southwest. By Christmas, the group fleet was reduced to 30 or fewer planes and the remaining elements of the group was effectively consolidated into the 501st Bombardment Group. Many of the remaining personnel signed for "any conditions of travel" to get home, arriving three weeks later in Oakland, California, where troop trains scattered them for points of discharge close to their homes.
