context_page_description: The Indonesian Air Force is the aerial branch of the Indonesian National Armed Forces. The Indonesian Air Force is headquartered in Jakarta, Indonesia and is headed by the Chief of Staff of the Air Force. Its order of battle is split into three Air Force Operational Commands. Most of its airbases are located on the island of Java. The Indonesian Air Force also has its ground force unit, called Air Force Special Forces Corps. The corps is also known as the "Orange Berets" due to their distinctive color of their service headgear. In addition, while not part of the Air Force, most of the personnel of the Indonesian National Air Defense Forces Command are picked from the Air Force, and its commander is always an Air Force two-star Marshal.
  The Indonesian Air Force has 37,850 personnel and equipped with 110 combat aircraft. The inventory includes five Su-27 and eleven Su-30 as the main fighters supplemented by 33 F-16 Fighting Falcons, Hawk 200, KAI T-50 and Embraer EMB314.
context_section_description: After the Japanese announced their surrender at the end of WWII, Indonesian nationalist leader Sukarno declared Indonesian Independence on 17 August 1945. Several days later, the Indonesian People's Security Bureau (Badan Keamanan Rakyat) was formed to undertake security duties. The Air Division of this force was also formed, using ex-Japanese planes scattered everywhere, especially in the island of Java, including Bugis Air Base in Malang (Established on 18 September 1945). The most numerous of these aeroplanes were the Yokosuka K5Y1 Willow (Cureng) trainers, which were hastily used to train newly recruited cadets. At the time of the founding, there was only one Indonesian holding a multi-engine pilot license from the pre-war Dutch Flying School, Flying Officer Agustinus Adisucipto (but did not have an opportunity to fly during the 3.5-year Japanese occupation). He was assisted by a few Japanese pilots who decided to stay in the newly born country. The new roundel was created simply by painting white on the lower part of the Japanese Hinomaru, reflecting the red and white of the Indonesian flag.  The People's Security Bureau was then, in October, re-organized to form the nascent formal armed forces. This marked the birth of the Indonesian Air Force on 9 April 1946. However, tensions rose as the Dutch tried to re-claim their former colony and launched an assault on 21 July 1947, destroying most of the planes on the ground. Some planes survived though and were hidden in remote bases.
  29 July 1947 was date of the first air operation by the newborn air force as three surviving aircraft, comprising two Yokosuka K5Y1 Willow (Cureng) and a Mitsubishi Ki-51 Sonia (the fourth aircraft, a Nakajima Ki-43 Oscar (Hayabusa) flown by Air Cadet Bambang Saptoadji, should also have been involved in the raid as an escort, but as of when it was launched, the aircraft was not airworthy due to engine troubles) conducted air raids at dawn on the Dutch Army barracks in Semarang, Salatiga and Ambarawa, dropping incendiary bombs. Tactically, these raids did not have any effect on the Dutch positions, but psychologically, it was a great success as it proved that the Indonesian Air Force still existed. The Dutch had previously claimed the destruction of Indonesian Air Force in their assault before and they never expected any attack from the sky. Dutch Curtiss P-40E Warhawks tried to find all the guerrillas' planes, but they were too late to find those "ghost" aircraft which landed quickly in Maguwo Air Base, near Yogyakarta (now, Adisucipto International Airport).  Indonesian pro-independence guerrillas tried to save captured aircraft in a number of remote areas, including examples of the Mitsubishi A6M Zero-Sen "Zeke", Aichi D3A "Val", and Mitsubishi G4M "Betty".
  Under pressure from the United Nations, the Dutch finally agreed to acknowledge Indonesian independence. Following the 1949 Round Table Conference, sovereignty was officially transferred to the United States of Indonesia. The Dutch armed forces left (but remained in West Papua until 1963) and the aeroplanes were handed over to the Indonesians. These comprised, among others, North American P-51 Mustang, North American B-25 Mitchell, North American T-6 Texan, Douglas A-26 Invader, Douglas C-47 Dakota and Consolidated PBY-5A Catalina, which served as the main forces of the Indonesian Air Force for the following decade. During this era, Indonesia received its first jet aircraft; De Havilland DH-115 Vampire. It was also during this era that the national roundels were changed to the red and white pentagon (which was supposed to signify Indonesia's national ideology of "Panca Sila", or the "Five Principles", created by Sukarno in 1945).
