During the tremendous U.S. Air Force Strategic Air Command (SAC) expansion of the early and mid-fifties, bases become overcrowded, with some of them supporting as many as 90 B-47s and 40 KC-97s. The first B-52 wings were also extremely large – composed of 45 bombers and 15 or 20 KC-135s, all situated on one base. As the Soviet missile threat became more pronounced and warning time became less, SAC bases presented increasingly attractive targets. It was necessary to break up these large concentrations of aircraft and scatter them throughout more bases. Several KC-97 squadrons were separated from their parent B-47 wings and relocated to northern bases. The B-47 dispersal program was a long range one and would be affected primarily through the phase out of wings in the late fifties and early sixties.

With the B-52 force, which was still growing, dispersal became an active program in 1958. Basically the B-52 dispersal program called for larger B-52 wings already in existence to be broken up into three equal-sized wings of 15 aircraft each, with two of them being relocated, normally to bases of other commands. In essence, each dispersed B-52 squadron became a strategic wing. This principle would also be followed in organizing and equipping the remained of the B-52 force. Headquarters USAF established the entire force at 42 squadrons in 1958. Ideally, each B-52 wing would have an air refueling squadron of 10 or 15 aircraft.

By the end of 1958, SAC had activated 14 strategic wings, but only three had aircraft assigned. The others were in various stages of development, with some having only a headquarters and one officer and one airman authorized".Office of the Historian, Headquarters Strategic Air Command, Offutt AFB, NE. The Development of the Strategic Air Command 1946–1986, Pages 72–73

Redesignation to AFCON status When the B-52 dispersal began in the fifties, the new units created to support this program were named strategic wings and given four-digit designations, for example, the 4137th Strategic Wing. Under the USAF organization and lineage system, these four-digit units fell into the MAJCOM (major air command controlled) category and their lineage (histories, awards, and battle honors) ended with their discontinuance and could never be revived. In sharp contrast, AFCON (Headquarters USAF controlled) units, which were readily distinguished by having one, two or three digit designations, could go through a series of inactivations and activations and still retain their lineage.

Headquarters SAC was well aware of the historical significance of records and accomplishments of the strategic wings and the need to perpetuate this lineage as well as the lineage of many illustrious unit that were no longer active.

In order to retain the lineage of the combat units and to perpetuate the lineage of many currently inactive units with illustrious World War II records, Headquarters SAC received authority from Headquarters USAF to discontinue its strategic wings that were equipped with combat aircraft and to activated AFCON units, most of which were inactive at the time.

The reorganization process, which extended from 1 January through 1 September, was applied to 22 B-52 strategic wings, three air-refueling wings, and the 4321st Strategic Wing at Offutt Air Force Base, Nebraska. These units were discontinued and two and three-digit AFCON units were activated. In most cases, the bombardment squadron that had been assigned to the strategic wings were inactivated and bombardment squadrons that had previously been assigned to the newly activated wings were activated. While these actions were almost tantamount to redesignation, they were not official redesignation. Therefore, the records, awards and achievements of the strategic wing could not be inherited by the bomb wings".Office of the Historian, Headquarters Strategic Air Command, Offutt AFB, NE.
