330th Aircraft Sustainment Group  The 330th Aircraft Sustainment Group was a group of the United States Air Force stationed at Robins Air Force Base, Georgia. It was last active in June 2010  The 330th Bombardment Group was constituted on 1 July 1942 at Salt Lake City Army Air Base, Utah. It was assigned to Second Air Force as a Consolidated B-24 Liberator Operational Training Unit (OTU) and later as a Replacement Training Unit (RTU). The group performed this training at Alamogordo Army Airfield in New Mexico, then later at Biggs Field near El Paso, Texas. With the drawdown of heavy bomber training in 1944, the group was redesignated as the 330th Bombardment Group, Very Heavy and became a Boeing B-29 Superfortress operational bomb group being assigned to the 314th Bombardment Wing, to be sent to the Pacific Theater as part of the war against the Japanese Empire. The group was assigned to Walker Army Air Field, Kansas for equipping and training. The group deployed to Guam in late 1944, and was assigned to XXI Bomber Command of the Twentieth Air Force. It entered combat on 12 April 1945 with an attack on the Hodogaya chemical plant at Koriyama, Japan. From April to May 1945, it struck airfields from which the Japanese were launching suicide planes against the invasion force at Okinawa. After that, operations were principally concerned with incendiary attacks against urban-industrial areas of Japan. It received a Distinguished Unit Citation for incendiary raids on the industrial sections of Tokushima and Gifu and for a strike against the hydroelectric power center at Kofu, Japan, in July 1945. Another DUC was received for attacking the Nakajima-Musashino aircraft engine plant near Tokyo in August 1945. The unit dropped food and supplies to Allied prisoners and participated in several show-of-force missions over Japan after the war. The Group remained in Western Pacific, although largely demobilized in the fall of 1945. Some aircraft were scrapped on Tinian; others flown to storage depots in the United States. the group was inactivated in December 1945. With the end of World War II, the 330th was allotted to the Air Force Reserve. It was redesignated as the 330th Bombardment Group, and stationed at March Air Force Base, California for training with Boeing B-29 Superfortresses as a corollary unit of the active-duty Strategic Air Command 22d Bombardment Group.
