Royal Thai Air Force bases The Royal Thai Air Force maintains a number of modern bases which were constructed between 1954 and 1968, have permanent buildings and ground support equipment. All but one were built and used by United States forces until their withdrawal from Thailand in 1976 when the RTAF took over the installations at Takhli and Nakhon Ratchasima (Korat). In the late 1980s, these bases and Don Muang Air Base outside Bangkok, which the air force shares with civil aviation, remain the primary operational installations. Maintenance of base facilities abandoned by the United States (Ubon, Udorn) proved costly and exceeded Thai needs; they were turned over to the Department of Civil Aviation for civil use. Nonetheless, all runways were still available for training and emergency use. By 2004 the Royal Thai Air Force had its main base at Don Muang airport, adjacent to Don Mueang International Airport. The RTAF also had large air fields and facilities at Nakon Ratchasima Ubon Ratchathani, and Takhli.
