The history of the Air Force began with the formation of the People's Security Agency (BKR) on August 23, 1945, to strengthen the Air Fleet which at that time was very short of airplanes and other facilities. In line with its development, it changed to the People's Security Army (TKR) on October 5, 1945 under the name TKR Aviation Office under the leadership of Air Commodore Suryadi Suryadarma. On January 23, 1946 the TKR was upgraded to TRI. As a continuation of the development of the Air Force's buds, then on April 9, 1946 the Flight Bureau TRI was abolished and replaced with the Republic of Indonesia Air Force which is now commemorated as the birth day of the Indonesian Air Force which was inaugurated simultaneously with the establishment of the Indonesian National Army (TNI).
