IV Bomber Command emblem (approved 4 December 1941)
The IV Bomber Command is an inactive United States Army Air Forces unit. It was last assigned to Fourth Air Force, based at San Francisco, California. It was inactivated on 31 March 1944. It trained bombardment organizations and personnel. Also flew antisubmarine patrols along the west coast.
In early 1941, the Army Air Forces (AAF) redesignated its geographical air districts in the United States as Air Forces. In the fall of that year, the new air forces were organized into commands, which typically included a bomber command, an interceptor command, an air support command and an air base command. In this reorganization IV Bomber Command was formed at Davis-Monthan Field, Arizona to control the bombardment units of Fourth Air Force in September. The new command drew much of its initial cadre from the 1st Bombardment Wing, which had been stationed there since May.
In the spring of 1944, the AAF reorganized its training units to provide more flexibility in manning, rather than continuing to use rigid table of organization units. In this reorganization, the command was disbanded on 31 March 1944 and its personnel absorbed into the 400th AAF Base Unit (Headquarters, Fourth Air Force).
Constituted as the 4th Bomber Command on 1 September 1941[note 1]
