The IV Bomber Command is a disbanded United States Air Force headquarters. It was established in September 1941, shortly before the attack on Pearl Harbor to command bomber units assigned to 4th Air Force. Following the entry of the United States into World War II, it flew patrols off the Pacific coast. However, its main efforts soon began organizing and training bomber units and aircrews. It was disbanded at San Francisco, California on 31 March 1944.

History

Background and organization

GHQ Air Force (GHQ, AF) had been established with two major combat functions, to maintain a striking force against long range targets, and the air defense of the United States.^[2] In the spring of 1941, GHQ, AF reorganized its Southwest Air District as 4th Air Force. To carry out its mission of training and maintaining a strike force, 4th Air Force organized a provisional Bomber Command, 4th Air Force at March Field by April 1941. In September, the provisional command was replaced by 4th Bomber Command at Davis-Monthan Field, Arizona in September 1941. The command moved to Hamilton Field, California, after the attack on Pearl Harbor.^[1] The new command drew much of its initial cadre from the 1st Bombardment Wing, which had been stationed at Davis-Monthan since May.^[3]

Operations

Shortly after the command became organized, the attack on Pearl Harbor caused the command to relocate to move to Hamilton Field and concentrate its efforts on antisubmarine patrols off the southern Pacific coast, reinforcing units of the Western and Northwestern Sea Frontiers of the United States Navy.^[4] However, it shortly became apparent that there was little threat from Japanese submarines. and the command shifted its focus to the training of bomber units and crews. Simultaneously, the AAF moved almost all its heavy bomber training in Second Air Force, while Fourth Air Force focused on fighter aircraft, training, so the command did not grow.^{[citation needed]}

In late 1943, some heavy bomber training was moved from Second Air Force, which had been the primary command for that training, to the command in order to enable combined training between fighters and bombers. In conjunction with this transfer, the command adopted the three phase training system for its training units: Phase I (individual training); Phase II (crew training) and Phase III (unit training).^[5]

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.^[6] 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).^[1]^[7]
