In addition to the USAF, A single RB-52B (52-008) was flown by the National Aeronautics and Space Administration (NASA) until it was retired on 17 December 2004.
One other B-52H (61-0025) was flown for many years by the Air Force Flight Test Center at Edwards, and was transferred to NASA on 30 July 2001 as a replacement for the RB-52B.
Beginning in 1962, in order to retain the lineage of the Strategic Wings as combat units and to perpetuate the lineage of many currently inactive bombardment units with illustrious World War II records, Headquarters SAC received authority from Headquarters USAF to discontinue its MAJCOM strategic wings that were equipped with combat aircraft and to activate AFCON units, most of which were inactive at the time which could carry a lineage and history.
Therefore, the history, lineage and honors of the World War II historical units were bestowed upon the newly established wing upon activation.
Andersen AFB & Kadena AB started primarily with B-52Fs and later B-52Ds aircraft; aircrew and support personnel deployed from CONUS B-52 wings on a rotational basis / U-TAPAO AB started operation after the B-52D became the primary mission aircraft; SW(P)72 at Andersen AFB was only equipped with B-52Gs
