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 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
