On 1 July 1978, the 306th Strategic Wing of SAC was transferred to Mildenhall from Ramstein Air Base, West Germany with a Boeing KC-135 Stratotanker air refuelling and a Boeing RC-135 reconnaissance mission. The 306th SW also functioned as the focal point for all SAC operations in Europe, and became the host unit at Mildenhall. Post Cold War (1990s) The 306th Strategic Wing operated at RAF Mildenhall until 1 February 1992, when the 100th Air Refueling Wing of USAFE, assumed the 306th SW responsibilities, and became host unit at Mildenhall, along with becoming Headquarters European Tanker Task Force with its KC-135 Stratotankers. In May 1993, as part of the drawdown of forces in Europe, it was announced that the majority of the USAF-operated base at RAF Alconbury was to be returned to the British Ministry of Defence. As a part of this return, the 352nd Special Operations Group and its associated aircraft, the MC-130E Combat Talon, HC-130P/N Combat King and MH-53 Pave Low, transferred to RAF Mildenhall in March 1995. 2000–present During the 2003 invasion of Iraq, the 491st Air Expeditionary Group (491st AEG) operated from the base, with the 491st Air Expeditionary Aeromedical Evacuation Squadron and the 744th Expeditionary Airlift Squadron, flying the Lockheed C-141C Starlifter.
