Royal Thai Air Force Bases
During 1954–1975 (the Vietnam War or Second Indochina War), the Thai Government allowed the Joint United States Military Advisory Group - Thailand (JUSMAG-THAI) to fund and manage the modernization of Royal Thai Air Force bases. In an unsigned agreement these airbases were to be operated by the United States Air Force for the specific purpose of attacking North Vietnam with some 500 airplanes. These bases were supplied by a Naval Base near the deep-water port of Sattahip. Many American military specialists were assigned to JUSMAG-THAI in Bangkok. As many as 45,000 US military  personnel were stationed in Thailand. History. The RTAF command structure consists of headquarters and five groups, which are: command group, combat group, support group, education and training group, and special services group. During the 1960s Thailand experienced one of the most rapid growth rates among developing countries: more than 10% per year in GNP, and about 8% per year in real output. The First National Economic Development Plan (1961-1966) was successfully implemented. US grant economic assistance totalled about US$500 million through the end of 1970. Direct military assistance totalled another US$800 million for the same period, continuing  at the rate of US$25–55 million per year. According to US government statistics, between 1950 and 1987 the US provided Thailand with more than US$2 billion in military assistance. The vast nature of this enterprise enriched Thailand at every level of society, enabling a jump in indigenous heavy construction, communications, transportation, and defense.
