USAF Korean Air Bases (K-Sites) codes, 1950-1953

During the Korean War, the Far East Air Force (FEAF) operated numerous air bases in Korea, many of which were former Japanese airfields upgraded and expanded by the United States. These air bases were designated with a “K” number to prevent confusion among locations, as the spelling of Korean locations on maps varied greatly, and villages had both Korean and Japanese names.

A topical Korean air base at the end of the war is shown in this June 1953 photo of K-9 (Pusan East). In the middle of the base, there are temporary buildings made of corrugated metal, while on the right side, there are tent barracks. (U.S. Air Force photo)

It is possible that the status of some of these locations changed during the war, such as an airfield being redesignated as an air base. In addition to the main air bases, the FEAF also established scores of auxiliary and emergency airstrips, which were designated with an “X-.” For example, X-83 was one of the auxiliary and emergency airstrips established during the Korean War.
