In December 1948, Air Defense Command (ADC) and TAC were brought together to form Continental Air Command (ConAC). HQ TAC was reduced to the status of an operational headquarters under CONAC. This move reflected an effort to concentrate all fighter forces deployed within the continental United States (CONUS) to strengthen the air defense of the North American continent. The creation of ConAC was largely an administrative convenience: the units assigned to ConAC were dual-trained and expected to revert to their primary strategic or tactical roles after the air defense battle was won. Two years later, on 1 December 1950, the Air Force reestablished Tactical Air Command as a major command and removed it from assignment to ConAC in large part due to the need to deploy personnel and aircraft to Japan and South Korea due to the Korean War.
