title: Army Air Forces Tactical Center
text: # Army Air Forces Tactical Center
  
  The Army Air Forces Tactical Center was a major command and military training organization of the United States Army Air Forces during World War II. It trained cadres from newly formed units in combat operations under simulated field conditions around which new combat groups would be formed. It was established as the Army Air Forces School of Applied Tactics (AAFSAT) in 1942 and redesignated the following year.
  
  In addition to its training function, the school also developed as a tactical doctrine development center, assuming the functions formerly assigned the Air Corps Tactical School. In June 1946, the center became the Army Air Forces Proving Ground Command.
  
  ## History
  
  ### Background
  
  As the threat of entry of the United States into World War II increased, the United States Army decided to close the Air Corps Tactical School in 1940 in order to use its experienced personnel at headquarters, and in expanded training and tactical units. As a result, the responsibility for the development and change to tactics for Air Corps units was scattered among various Air Corps units. Moreover, no single element of the Air Staff or special committee was responsible for overseeing tactical doctrine for the Army's air elements. The field organizations primarily responsible for development of tactics and associated doctrine were the Army Air Force Board, the Air Defense Board, the Fighter Command School and the Army Air Forces Proving Ground. In addition, the splitting of existing combat groups into cadres for new groups had become impracticable as the number of new groups increased. At the entry of the United States into World War II on 7 December 1941, the Army Air Forces (AAF) had expanded to 67 groups from a pre-1939 total of 15, but approximately half were paper units just forming. The entry into the war meant an immediate significant increase in the numbers of new combat groups, expanding to 269 groups by the end of 1943.
  
  ### Formation of the Army Air Forces School of Applied Tactics
  
  Headquarters USAAF originally intended that four tactical schools be developed across the United States, one each for air defense, air service, air support and bombardment. However "to save administrative costs and physical outlay" and to facilitate coordination between the schools, all four would be consolidated at a single location. Orlando Army Air Base, Florida was chosen 1 November 1942, primarily because it was already the location of Fighter Command School, which would be subordinated to the Army Air Forces School of Applied Tactics (AAFSAT). The AAF determined this organization would conduct tactical development and training and provide tactical training for flyers who were preparing to deploy to theaters of operation. The commandant of AAFSAT was Brigadier General Hume Peabody, formerly the assistant commandant of the Air Corps Tactical School.
  
  The Fighter Command School became AAFSAT's Air Defense Department at once. The 91st Service Group at Fort Dix Army Air Field moved to Orlando and became the Air Service Department. 5th Interceptor Command moved from San Francisco and became the Interceptor Command School. The other two departments, Air Support and Bombardment were built up from scratch AAFSAT was organized into three directorates: Tactical Development, School Activities, and Demonstration Air Force, with three combat groups acting as both school units and demonstration air force units. The Directorate of School Activities was responsible for the four functional departments.
  
  The school officially opened 12 November 1942. An important component was the Army Air Forces Board, which supervised developmental projects. This board also assigned developmental projects to AAFSAT's departments, and had two subordinate boards, the Air Defense Board and, after April 1943, the AAF Equipment Board. Although the Board had been operating before AAFSAT was activated, it only became official in July, when the school became the AAF Tactical Center. It was reassigned from the center directly to Headquarters, AAF in October 1943.although the commandant of the center remained a member of the board.
  
  ### Army Air Forces Tactical Center
  
  In October 1943, AAFSAT was reorganized and became the Army Air Forces Tactical Center. A "new" AAFSAT was organized as one of the center's subordinate units. The first group receiving AAFSAT training to deploy overseas was the 390th Bombardment Group in July 1943, based in England with the Eighth Air Force. By September 1945, the AAF Center had trained 54,000 personnel and the cadres of 44 bombardment groups.
  
  During 1943-1945 the AAF Tactical Center operated a combat simulation facility in Florida. Units and airfields were established throughout an 8,000-square-mile (21,000 $km^2)$ area of north central Florida designated a mock "war theater" stretching roughly from Tampa to Titusville to Starke to Apalachicola in which war games were conducted. AAFSAT also had a bombing range at Ocala AAF, a service center at Leesburg AAF, and an air depot at Pinecastle Army Air Field.
  
  ### Transfer and transition
  
  Due to a major reorganization of the Tactical Center and a change in the types of courses conducted by the institution, the Army Air Forces redesignated the "new" AAFSAT as the Army Air Forces School on 1 June 1945, while the Tactical Center dropped the "Tactical" from its name and became the AAF Center. Following the end of World War II, in preparation for its post-war educational operations, the AAF moved the AAF School from Orlando to Maxwell Field, Alabama on 29 November 1945 and assigned it directly to Headquarters, AAF. Having lost its developmental function, the AAF Center moved to Eglin Field in March 1946 and became the Army Air Forces Proving Ground Command.

  ### School units
  
  The AAF Tactical Center medium and heavy bomber school unit from 31 October 1942 was the 9th Bombardment Group. In February 1943, a close air support school unit, the 415th Bombardment Group was added. The fighter school unit from 23 March 1943 was the 50th Fighter Group. Night Fighter training initially began with the 50th Group's 81st Fighter Squadron, but by 1943 was concentrated in the 481st Night Fighter Operational Training Group.
  
  However, the AAF was finding that standard military units like these groups, based on relatively inflexible tables of organization not well adapted to the training mission. Accordingly, it adopted a more functional system in the spring of 1944 in which each base was organized into a separate numbered unit. In preparation for this reorganization, the 9th Bombardment Group moved to Nebraska, where it was reassigned to Second Air Force to become a Boeing B-29 Superfortress unit. The 50th Fighter Group began to concentrate on training in preparation for deployment to the European Theater of Operations in March 1944, the 481st Night Fighter Operational Training Group continued its mission, but transferred to Fourth Air Force in California in January 1944. The transition to the new organization took place on 14 April 1944.
  
  With a ground school at Orlando Army Air Base, Florida, presenting a two-week academic course, AAFSAT also taught a two-week field course utilizing eleven training airfields in Florida representing all conditions likely to be found in combat, from bare fields to prepared bomber air bases having 10,000-foot (3,000 m) runways.
