June 1952 – 2 September 1952) (B-50D, KB-29P) (TDY from Walker AFB New Mexico) In 1953, Mildenhall's mission was changed from a B-50 bomber airfield to a KC-97 Stratofreighter aerial tanker dispersal base. The role was to support Boeing B-47 Stratojet aircraft based at RAF Fairford. The base became the home for the United Kingdom Passenger Terminal managed by Military Air Transport Service (MATS) in 1958. 7513th Tactical Group SAC departed Mildenhall in 1959, as its runway capabilities no longer met the requirements for its newer aircraft. On 17 July 1959, SAC and USAFE reached an agreement facilitating and substantially increasing Third Air Force's role in making operational decisions regarding the USAF units in the UK. On 1 September, the 7513th Tactical Group took over host unit responsibilities. On 15 November 1965 Mildenhall welcomed the arrival of the Silk Purse Control Group and the 7120th Airborne Command and Control Squadron (7120 ACCS) previously stationed at Chateauroux Air Station, France. Upon its arrival at Mildenhall, the 7120th ACCS converted from the Douglas C-118 to the Boeing EC-135 which were used as airborne command posts for the Commander, US European Command under the code name Operation Silk Purse. 513th Tactical Airlift Wing On 1 July 1966, the 513th Troop Carrier Wing arrived at Mildenhall from Evreux-Fauville Air Base in France. With its activation on Mildenhall, the 513th TCW assumed operational control of two rotational (7441st, 7742nd) Troop Carrier Squadrons of twenty C-130 Hercules as well as the 7120th ACCS / Silk Purse Control Group and the five Boeing EC-135H. For the next few years, Mildenhall witnessed little change: however, in June 1972, the base added to the list of its tenants with the arrival of Headquarters Third Air Force, which relocated from South Ruislip. In May 1969, mechanic Sergeant Paul Meyer, homesick for his wife in Virginia, stole a Hercules C-130E transporter and flew south, eventually ditching in the English Channel. In April 2018 an underwater search of the aircraft, using sonar, was announced by the Deeper Dorset group. 306th Strategic Wing The next significant event in Mildenhall's history came with the arrival of Detachment 4, 9th Strategic Reconnaissance Wing (9th SRW) in 1976, which controlled rotational U-2 and SR-71 Blackbird operations from the base. From their arrival, until the departure of the last SR-71 on 18 January 1990, the 306th Strategic Wing's SR-71 and U-2 aircraft came to symbolise RAF Mildenhall
