TF-104G line for the last flight March 16, 1983 The host 4510th Combat Crew Training Wing (CCTW) at Luke was tasked with providing the advanced flying training. The operational organization for the program underwent several changes be-fore solidifying. Originally, the advanced training was to have been conducted under an Assistant Deputy Commander for Operations in the 4510th CCTW. On January 27, 1964, however, a Director of GAF Training was created as a staff office under the Deputy Commander for Operations. Command and control problems were foreseen with the latter arrangement, and on February 20, 1964, the 4540th Combat Crew Training Group (CCTG) was organized and designated to conduct GAF training at Luke. The group was activated on April 1, 1964. Prior to designating the 4540th CCTG, an operational squadron had been activated under the 4510th CCTW to conduct the training: The 4518th Combat Crew Training Squadron (CCTS) was activated on March 1, 1964 and was reassigned to the 4540th CCTG upon the later's activation (April 1, 1964). The same special order that designated and organized the 4540th CCTG also provided for an existing 4510th CCTW unit, the 4512th Combat Crew Training Squadron (CCTS), to be assigned to the group, effective July 1, 1964. copyright © Walt Harrison archive
