US Air Force crews ferried two MC-130J Commando II Special Operations tankers from the Lockheed Martin facility in Marietta, Georgia, to the US base at RAF Mildenhall in the United Kingdom on 5 December 2014. These aircraft (US Air Force serial numbers 12-5759 and 12-5760) will be operated by the 67th Special Operations Squadron at Mildenhall. The Commando II supports such missions as in-flight refueling, infiltration/exfiltration, and aerial delivery and resupply of Special Operations forces. MC-130Js are also based at Kirtland and Cannon AFBs in New Mexico in the United States.
