ceased to exist as flying unit in the late summer of that year. Inactivated December 1946, the group received the Distinguished Unit Citation with one Oak Leaf Cluster and six campaign stars. Cold War The group was reactivated as a Strategic Air Command (SAC) Boeing B-29 Superfortress very heavy bombardment group but was redesignated in 1948 as a medium bombardment group when the B-29 was reclassified as a medium bomber. The group trained in the United States for strategic bombardment operations. Deliveries of the new Boeing B-47 Stratojet to the USAF began in December 1950, and the aircraft entered service in May 1951 with the group at MacDill AFB, Florida. The 306th was intended to act as a training organization in to prepare future B-47 crews and the 306th's B-47As were primarily training aircraft and not considered as being combat ready; none of the B-47As ever saw any operational duty. On 19 November 1951, the 306th received its first operational Boeing B-47B and christened it "The Real McCoy" in honor of Colonel Michael N. W. McCoy, the 306th's wing commander, who flew it from the Boeing Wichita plant to MacDill AFB. In 1950 the group added the air refueling mission when the 306th Air Refueling Squadron was activated and assigned to the group. The first Boeing KC-97E Stratofreighter tanker aircraft assigned to Strategic Air Command was delivered to this squadron in 1951. In February 1951, the group became non-operational and its squadrons were attached to the 306th Bombardment Wing at MacDill AFB, Florida. The 306th was inactivated as a group on 16 June 1952 and its operational squadrons were reassigned to the 306th Bombardment Wing as SAC converted its bomb groups to the dual deputy organization. Modern era The 306th was redesignated the 306th Flying Training Group and reactivated in October 2004 as part of Air Education and Training Command's (AETC) Nineteenth Air Force (19 AF) at the United States Air Force Academy. In addition to operating the USAF Academy Airfield and the associated aviation training activities for USAFA Cadets at that facility, the 306 FTG also has oversight of the Initial Flight Screening (IFS) program for USAF commissioned officer aviation candidates, including pilots and combat systems officers commissioned through Air Force ROTC and Officer Training School as well as the USAF Academy. IFS is performed under a civilian contract program at Pueblo Memorial Airport, Colorado and the 306 FTG
