Although the King of Thailand is the supreme head of the Thai armed forces (Thai: จอมทัพไทย), his position is only nominal. The ministry and the forces are administered by an appointed politician, the Minister of Defence, a member of the Cabinet of Thailand. The post of Minister of Defence has been held by General Prawit Wongsuwon, who is also Deputy Prime Minister, since August 2014.



Initially, the Ministry was called Krom Kalahom (Thai: กรมกลาโหม) and its head was called Samuha Kalahom (Thai: สมุหกลาโหม), and it was charged with the protection of the southern border. It was founded in the Ayutthaya period and was retained throughout the Rattanakosin period. The ministry in its current design was formed in 1887, by the order of King Chulalongkorn, to create a permanent military command. This was a result of the increasing threat posed by Western powers. The ministry was first housed in an old horse-and-elephant stable opposite the Grand Palace. A new European-style building was erected to house it. At first the ministry only commanded the army (founded in 1847), but then it incorporated the navy (founded in 1887), and finally, the air force (founded in 1913). In 1914, King Vajiravudh determined that the act providing for invoking martial law, first promulgated by his father in 1907, was not consistent with modern laws of war nor convenient for the preservation of the external or internal security of the state, so it was changed to the modern form that, with minor amendments, continues to be in force.[3]


For fiscal year 2018 (FY2018) the army's budget is 107,457 million baht; the navy's, 43,835 million baht; and the air force, 39,931 million baht.[2]
