Hobson Plan
The Hobson Plan was an organizational structure established by the United States Air Force in 1948, following experimental organization in 1947. Known as the "Wing-Base Organization," it replaced the organization used by the United States Army Air Forces, the predecessor organization of the USAF, which used separate chains of command for combat and support units. The plan made the wing the basic combat unit of the AAF, rather than the group and placed all support elements on a base under the command of the wing commander in addition to combat elements.
Background
United States Army Air Forces
As part of the United States Army, the operational units of the United States Army Air Forces operated from facilities known as army air fields. They consisted of a ground station, which consisted of streets, buildings, barracks and the support facilities and organizations. The airfield consisted of the runways, taxiways, hangars, and other facilities used to support flight operations at the airfield. The station commander commanded the station organizations and was responsible for the facilities. From 1940 to 1942, this responsibility fell to the commander of an "Air Base Group", consisting of an air base squadron and one or two materiel squadrons. There were also attached quartermaster and ordnance units, as well as other "Arms and Services with the Army Air Forces" detachments. Although these units supported one or two combat groups, they reported to different headquarters. In 1942, the air base groups became "service groups" designed to support deployed combat groups, while in the United States, the air base squadrons were expanded into "base headquarters and air base squadrons" and assumed the responsibilities of the former air base groups. In a reorganization of units in the United States by Army Air Forces, in the spring of 1944 the support units were reorganized into "Army Air Force Base Units".Creation of the United States Air Force
On September 16, 1947, the United States Air Force was established as a separate and equal element of the United States armed forces.Rapid demobilization after September 1945 meant that a new Air Force had to be built with the remnants of the wartime Army Air Forces. Initially, the Army Air Fields retained as permanent bases were assumed by the USAF were renamed as "Air Force Bases", and the Army's organizational structure was carried over into the new service with "Air Force Base Units" replacing the AAFBU. This resulted, however, into an awkward circumstance where the Combat Group commander was reporting to a Base Commander who may or may not have had flying experience. Once the United States Air Force became operational as a separate department, Carl Andrew Spaatz, the first Chief of Staff of the United States Air Force established a policy where, "No tactical commander should be subordinate to the station commander."
Spaatz's policy meant that a new solution would have to be found. Major General Charles Born proposed the creation of the Provisional Wing Plan, which basically reversed the USAAF organization and placed the wing commander over the base commander, although this idea was eventually discarded as it was viewed to be too complex.
The Wing-Base plan
Under the "Wing-Base" plan, the operational combat squadrons were assigned to a combat group. The support squadrons on the station were assigned to a "Maintenance and Supply Group", an "Airdrome Group", and a "Station Medical Group." The four groups were assigned to a wing, a changed level of command which unified all of the components, flying and support under a single command. The group commanders were subordinate to the wing commander who was an experienced combat flying leader. The wing would assume the historical numerical designation of the assigned combat group. A base commander was established to handle the administrative duties of the wing commander and to coordinate with the various group commanders. In this plan, known as the "Hobson Plan," the support groups and the operational flying combat group and the wing became one unit. Colonel Kenneth B. Hobson, the chief of the AAF Organizational Division, was the special project chairman and briefer. The Wing-Base Organization was formalized in Air Force Regulation 20–15, Organization Principles and Policies for the US Air Force.Organizations known as "wings" had existed in the Air Force and its predecessors since 1918, and new wings were created in the 1920s and 1930s. During World War II numerous wings existed; some provided training in the United States, others controlled combat groups and support organizations overseas. However, the USAF wings established in 1947 were new organizations and few shared lineage or honors with the wings formed under the Army. In 1948 and afterward, some existing AAF wings were redesignated as air divisions, and placed immediately above the USAF Wings and below the Numbered Air Forces in the USAF organizational pyramid.
Another major change implemented by the Hobson Plan was the standardization of designations. For example, the 1st Fighter Wing, established at March Air Force Base would consist of the 1st Fighter Group ; the 1st Maintenance and Supply Group, the 1st Air Base Group, and the 1st Station Medical Group. Subordinate to the groups were the 1st Field Maintenance Squadron, 1st Supply Squadron, 1st Engine Squadron, 1st Air Police Squadron, and so on. Operational flying Squadrons retained their historical designations and were assigned to the combat group. Tenant units stationed at the base, under the command of other commands, would also retain their designations.
1947 Service Test
The service test of the Hobson Plan in 1947-1948 prompted an important change in the field structure and organization of the Air Force. The AAF wing organizations supervised a mixture of combat groups and support organizations. None of the subordinate organizations were permanently affiliated with the wings, or possessed similar numerical designations or standard functions.The USAF wings organized for the service test of the Hobson Plan featured standard functions. Each wing had its support squadrons organized into the four prescribed groups, all with identical numerical designations.
