TNI AU

The Indonesian Air Force ( id, Tentara Nasional Indonesia Angkatan Udara (TNI-AU), literally "''Indonesian National Military-Air Force''") sometimes shortened as IDAF / IdAF, 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 ( id, Kepala Staf Angkatan Udara – KSAU or KASAU). Its order of battle is split into three Air Operations Commands ( id, Komando Operasi Udara). Most of its airbases are located on the island of Java. The Indonesian Air Force also has its ground force unit, called Air Force Quick Reaction Force Command ( Kopasgat). The corps is also known as the "Orange Berets" () due to the distinctive color of their service headgear.

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 (from Russia) supplemented by 33 F-16 Fighting Falcons (from the United States), Hawk 200, KAI T-50 and Embraer EMB314.''Tempo English Edition'' magazine, 19–25 October 2011 p17 The Indonesian Air Force intends to purchase 50 KF-X as a replacement for the already-aging US Northrop F-5 Tiger light fighters in its inventory In February 2021, Indonesian Air Force intends to purchase 36 Rafale and 8 F-15EX, along with C-130J and Medium-altitude long-endurance unmanned aerial vehicle.

History

Indonesian War of Independence / Netherlands 'Police Action' (1945–1949)

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).

Action against rebellions (1950–1961)

Political instability meant that the Indonesian Air Force saw action against several regional rebellions in Indonesia such as PRRI, Permesta, Darul Islam-Tentara Islam Indonesia (DI/TII) and the Republic of South Maluku separatists.

Several Indonesian pilots scored their first kills, including Captain Ignatius Dewanto with his North American P-51 Mustang, who in 1958 shot down a Permesta Douglas B-26 Invader over Ambon. Its pilot, Allen Pope, an American CIA agent, was captured and tried in Jakarta, thus revealing the significant involvement of the CIA's "Operation Haik" in the rebellion.

The most famous Indonesian fighter pilot in this era was Rusmin Nurjadin, who became Chief of Staff of the Air Force from 1966 to 1969. Nurjadin commanded MiG-21 squadrons in 1962–65 and founded an acrobatic team in 1962 that flew the MiG-17F/PF ''Fresco'' over some cities in Indonesia. Small numbers of Indonesian Air Force pilots gained their reputation as aces in this era.

Soviet influence (1962–1965)

The need to prop up to what became Operation Trikora in Netherlands New Guinea and the rise of the Communist Party of Indonesia drew Indonesia closer to the Eastern Bloc. Several Soviet-built aircraft began to arrive in the early 1960s including the MiG-15UTI from Czechoslovakia, MiG-17F/PF, MiG-19S and MiG-21F-13, in addition to Ilyushin Il-28, Mil Mi-4, Mil Mi-6, Antonov An-12 and Avia 14 also from Czechoslovakia. Indonesia also received Lavochkin La-11, as well as Tupolev Tu-2 from China, intended to replace the B-25, but they never reached operational status. These aircraft served along with the remaining American aircraft such as North American B-25 Mitchell, Douglas A-26 Invader, Douglas C-47 Dakota and North American P-51 Mustang. It was during this period that the Indonesian Air Force became the first Air Force in Southeast Asia which acquired the capability of strategic bombing by acquiring the new Tupolev Tu-16 in 1961, before the acquisition of Ilyushin Il-28 by Vietnam People's Air Force. Around 25 Tu-16KS were delivered complete with AS-1 air-surface missiles. One crashed at the end of 1962.Gordon & Rigmat(2004) p120Djoko Poerwoko (2001) p97 To add with all these purchases was the first ever surface to air air defense missile operated by Southeast Asians, the S-75 Dvina, which were acquired in 1961.

This era also marked the last confrontation with the Dutch in Papua, before the Dutch, again under pressure of the United Nations, left in 1963. Several missions of Taiwan-based Lockheed U-2s from 35th Squadron flew over Maluku (Moluccas) and reported to Dutch military that there was a strong possibility that the Dutch would lose their air superiority over Papua if they continued the war.Angkasa Edisi Koleksi No. 73, Operasi Udara Trikora, Year of 2011, Page 38. During ''Operation Trikora'', the air force was deployed as follows:

*7 P-51Ds based at Laha airbase, Ambon. One aircraft piloted by Second Lieutenant (AF) Prasetyo lost due to engine failure during the ferry flight from Makassar to Ambon. Prasetyo died after bailing out from the aircraft, landing in high-tide seas and could not be rescued by the Air Force's PBY-5 Catalina due to the extreme weather after his accident.
*40 MiG-17F/PF aircraft on three airfields: Morotai (in northern Maluku), Amahai (in Seram) and Letfuan (in Kai Islands, located in the southwest of Papua). The aircraft had been stationed at Morotai before ''Operation Trikora'' for actions against PRRI- Permesta and the Republic of South Maluku separatists. The primary role of these aircraft were to provide air cover for the airlift and logistics aircraft during the early infiltration to Papua.Angkasa Edisi Koleksi No. 73, Operasi Udara Trikora, Year of 2011, Page 38 If the war broke out, these MiG-17F/PF would provide the air cover for Tu-16 anti-shipping missions and Il-28 bombing missions, also for intercepting Dutch Hawker Hunters based in Numfor, Biak.

*4 B-25 Mitchells and two A-26 Invaders at Letfuan airbase. Their primary role was for transport and providing air cover for the airlift, until this role was assumed by the P-51Ds and MiG-17F/PFs. Dutch Lockheed P2V Neptunes were known as the strongest rival for these Letfuan-based units.Angkasa Edisi Koleksi No. 73, Operasi Udara Trikora, Year of 2011, Page 44-46
*18 Il-28s stationed first at Laha airbase, but then moved to Amahai airbase, due to the shortness of runway at Laha for the landing of the aircraft.Angkasa Edisi Koleksi No. 73, Operasi Udara Trikora, Year of 2011, Page 39
* 26 Tu-16s stationed in Iswahyudi Air Force Base near Ngawi, East Java in 41st and 42nd Squadron. Six aircraft were scrambled to Morotai airbase for the operation. These units were to threaten the Dutch naval fleet in Papua including HNLMS Karel Doorman (R81), the only aircraft carrier of the Dutch naval fleet.
*24 Douglas C-47 Dakotas stationed at three airfields; Laha, Amahai and Letfuan. During an operation at Papua, one aircraft piloted by Captain (AF) Djalaludin Tantu and co-pilot Second Lieutenant (AF) Sukandar, was downed by a Dutch P2V. All crews bailed out safely from the aircraft, but were then captured by the Dutch forces.
*10 Lockheed C-130 Hercules stationed at Halim Perdanakusuma airbase at Jakarta. Despite the warning from United States to not use the aircraft for the operation, it soon scrambled over the Papua for the airlift mission, due to the loss of C-47s, to Dutch Hawker Hunters and P2V Neptunes. The C-130's high altitude flying capability made it less vulnerable to interception.
*6 Douglas DC-3s and one Convair 240, under Wing Garuda 011. The aircraft were modified from civilian use for airlift operations.
*6 anti-submarine Fairey Gannet AS.4s, several PBY-5 Catalinas and two Grumman HU-16 Albatross (UF-1 variant). These aircraft belonged to the Indonesian Naval Aviation, but supporting the air forces for the Operation. Aircraft were stationed in Liang airbase at Seram, then moved to Morotai airbase. One Gannet AS.4 was lost due to an accident when it crashed into a mountain in Seram island, killing three crew members.
*Several Bell 47s, Mil Mi-4 and Mil Mi-6 helicopters were planned to be used for the operation, but were not ready during the early phase of infiltration of the operation.

Indonesian MiG pilots received training to fly their fighter aircraft in Egypt before the infiltration campaign. During the infiltration of the airlift campaign, the air forces' special forces, (PGT) (now known as Kopasgat) landed in Klamono-Sorong, Papua.

Also during this period, the Indonesian Air Force also took part in the confrontation against Malaysia (which was backed by the United Kingdom) along the border of Kalimantan, the Malacca Strait and near the Singapore maritime border, wherein Air Force aircraft faced their counterparts in the Royal Air Force and the young Royal Malaysian Air Force.

30 September movement and the overthrow of Sukarno (1966–1970)

The coup attempt led by the 30 September Movement in 1965 changed everything and a new anti-communist regime from the Army, led by Major General Suharto, took power. The Chief of Staff of the Air Force, Air Marshall Omar Dani was removed from his position and court-martialed for his purported involvement in the coup. Ties with the Eastern bloc countries were cut, and thus support and spare parts for the planes became short. By August 1968 the situation was critical, and in early 1970, the Chief of Staff of the Air Force, Suwoto Sukandar, said that the spare parts situation meant that only 15–20 percent of aircraft were airworthy. The MiG force made its farewell flight with a flypast of Jakarta in 1970. The relatively new MiG-19s were sold to Pakistan. By October 1970, only one Tu-16 was still flying, but after an in-flight engine failure, it too was grounded.joko Poerwoko (2001) p92-96/ref> But despite the problems, the Air Force still served with distinction in fighting militant remnants of the CPI in Java's provinces, particularly in Central and East Java.

With Suharto's assumption of the presidency and the office of Commander in Chief in 1967, the focus shifted to fighting the communist PGRS/Paraku insurgency. The Air Force launched Operation Lightning Strike ( id, Operasi Samber Kilat) to support ground troops eradicate Sarawak communists that were present in West Kalimantan and along Indonesia-Malaysia border by dropping troops to the target area, dropping logistical assistance, VIP transportation, medical evacuation and recon flights. The Air Force deployed Air Squadron 6 and 7 which were equipped with Mi-4, Bell 204B and UH-34D helicopters to the operation.

Rebirth (1970–1980)

The Air Force began to be re-equipped by receiving former Royal Australian Air Force (RAAF) CAC Sabres – an Australian re-design of the F-86 Sabre – to replace the MiG-21s. The Sabre was used by the TNI-AU until 1982. In 1973, the United States supplied military assistance including T33s trainers and UH-34D helicopters in exchange for four old MiG-21F-13s. Pakistan Air Force took over the responsibility to train Indonesian pilots in the Sabre and in logistical aspects of the Air Force. Over the next three years, the US supplied 16 North American Rockwell OV-10 Broncos counter-insurgency aircraft and F-5E/F Tiger II fighters, in exchange for which the Indonesian Air Force handed over the majority of its remaining MiG-21F-13s, which were used to form a US Air Force Aggressor squadron.Davies (2008) pp48, 51 Indonesia also purchased BAE Hawk Mk 53s from the United Kingdom in the 1970s.

The Indonesian Air Force took part in the 1975 Indonesian invasion of East Timor.

Influence of American and allied products (1980–1998)

In the early 1980s, the Air Force, needing modern strike aircraft, organised ''Operation Alpha'' to clandestinely acquire ex- Israeli Air Force A-4 Skyhawks. Air Force personnel were sent in secret by different routes and eventually Indonesia received 32 aircraft.Djoko Poerwoko (2001) p153-155

In 1982, Indonesia purchased 16 Northrop F-5E/F Tiger II from the United States to replace their Sabres under the Peace Komodo I and II. These were upgraded in Belgium from 1995.

During 1986–88, there was a competition for the contract to provide a new fighter bomber, between the General Dynamics F-16 and Dassault Mirage 2000. Indonesia eventually ordered 12 F-16A/B ''Fighting Falcon'' Block 15 OCU as a new fighter in 1989. The Indonesian Air Force had originally planned to acquire 60 F-16s to cover and defend its 12 million square kilometres of territory. A total of 10 F-16A and F-16B are still in service with Indonesian Air Force: 2 planes crashed in two different accidents. A follow-up order for 9 more F-16A Block-15 OCU was cancelled in favour of 24 Su-30KI, but this order was also cancelled due to the 1997 Asian Financial Crisis.

The Indonesian Air Force ordered eight BAE Hawk Mk 109s and 32 Mk 209s in 1993. The last of these was delivered by January 1997.

1998–2006 embargoes

In 1999, the Indonesian military staged a military intervention in East Timor following an independence referendum. The result was that more than 1,500 civilians were killed and 70 percent of Dili's infrastructure razed. In response, the United States and the European Union both imposed arms embargoes. Although the European Union chose not to renew its ban in 2000, the United States did not lift its embargo until November 2005. During this embargo, the Indonesian government turned to Russia to supply them with arms including fighters, helicopters, missiles, radars and other equipment.

In 2002, the Indonesian Air Force conducted operations against separatists, such as the Free Aceh Movement ''Gerakan Aceh Merdeka'' (GAM) and Free Papua Movement ''Organisasi Papua Merdeka'' (OPM). In the conflict with GAM in Aceh, the Indonesian Air Force utilised OV-10Fs for counter-insurgency actions along with BAe Hawk 53 and 209.

In that same year, the Air Force received two Sukhoi Su-27s and two Sukhoi Su-30s from Russia. The fighters were partly paid for in Indonesian palm oil. The purchase, however, did not include any weaponry. Seven KT-1B Korean basic trainers were also purchased.

By 2005 the Air Force was experiencing a logistical crisis. The F-16s and A-4s, which accounted for 80% of its air combat assets, were at the minimum or nil level of combat readiness. To respond to the crisis, in 2006, the Indonesian Air Force ordered three Sukhoi Su-27SKM and three Su-30MK2 to complete a full squadron. It was also made public that the four aircraft procured in 2003 were inactive and awaiting an upgrade of their communication systems, as they were incompatible with the Indonesian systems in use. The additional aircraft were ordered with systems complying with the Indonesian and international standards and would also include new weaponry for all variants. A further 12 KT-1b trainers were also ordered in 2006.

Until 2008, the Indonesian Air Force had only purchased four types of missiles: KS-1 Komet, Vympel K-13, AIM-9 Sidewinder and AGM-65 Maverick. Starting from 2008, it started receiving more advanced Russian made Vympel R-73 and R-77 air-to-air missiles for its new Su-27 and Su-30 fighters. Also, a limited number of Kh-29, Kh-31 and Kh-59 air-to-ground missiles were delivered for the Su-30s.

Local weapons are being developed such as P-100 air-to-ground bomb manufactured by PT Dahana and PT Sari Bahari Malang, East Java. P-100 has been successfully tested in Su-27 and Su-30 for ground attack missions. Large-scale production has received certification from Ministry of Defence.

Minimum Essential Force (MEF) 2010–present

During the visit of US President Barack Obama on 9–10 November 2010, the TNI-AU was offered 24 ex-USAF F-16 Block 25 aircraft as part of the Peace Bima-Sena II agreement. In October 2011, the House of Representatives approved the grant. The jets will be upgraded similar to the latest Block 50/52 variant with payment. The TNI-AU is also progressing with the reactivation of all 10 units of F-16 Block 15 OCU, which resulted in the reactivation of TS-1606, TS-1609 and TS-1612 recently. To replace the Fokker F-27s, the TNI-AU has ordered nine Spanish CASA C-295 in joint production with PT. Dirgantara Indonesia. New unmanned aerial vehicles will also be purchased to strengthen TNI-AU aerial observation and will be based at Supadio Air Force Base, Pontianak, Kalimantan Barat.

Starting in 2010, Minister of Defence Purnomo Yusgiantoro stated that TNI-AU will gradually purchase a total of 180 Su-27s and Su-30s to complete the needs of 10 squadrons. India also offered TNI-AU Indian-Russian made BrahMos
