Yunnanyi Airport, formerly known as Xiangyun Airport and during WWII as Beitun Airport, is a military airport in western Xiangyun County, Yunnan province, China.
During the Second World War, there were two airports in Xiangyun County: (after the nearby town,) and Beitun Airport . The original Yunnanyi Airport was abandoned after 1949. Beitun Airport stayed in use, and was renamed Xiangyun Airport. Xiangyun Airport was later renamed again to become the current Yunnanyi Airport.[1] [2] [3] [4] [5] [6]
During World War II, the original Yunnanyi Airport (also known as Yunnani or Siangyun Airfield) and was used by the United States Army Air Forces Fourteenth Air Force as part of the China Defensive Campaign beginning in September 1944. The airfield was primarily used by transport (C-46 Commando, C-47 Skytrain) squadrons arriving from India after flying over "the Hump". The transport aircraft unloaded supplies and equipment for the Chinese forces, primarily being food and ammunition. In addition, USAAF F-4 (P-38 Lightning) aircraft flew combat reconnaissance missions over Japanese-held areas from the airport in late 1944 and early 1945. The Americans closed their facilities at the airport in July 1945.
