The Turkish Air Force (TuAF) (Turkish: Türk Hava Kuvvetleri) is the air and space force of the Turkish Armed Forces. It traces its origins to 1 June 1911 when it was founded as the Aviation Squadrons by the Ottoman Empire. It was composed of the Army Aviation Squadrons founded in 1911, and the Naval Aviation Squadrons founded in 1914 which used seaplanes. The Air Force as a branch of the Turkish Armed Forces was founded by the Grand National Assembly of Turkey on 23 April 1920.
As of 2023, according to International Institute for Strategic Studies, the Turkish Air Force has an active strength of 50,000 military personnel and operates approximately 295 manned fixed-wing aircraft, 35 helicopters, and 52 unmanned aerial vehicles. In terms of aircraft quantity, it is the largest air force in Europe. The world's first black pilot, Ahmet Ali Çelikten, the world's first female fighter pilot, Sabiha Gökçen, and the first female jet pilot accredited in NATO, Leman Altınçekiç, all served in the Turkish Air Force.
The history of Ottoman military aviation dates back to between 20 June 1909 and 1 July 1911. In 1911, the former commander of the Action Army Mahmud Sevket Pasa achieved to send some Turkish military officers to the French Bleriot aviation school. The same year the establishment of a Turkish airforce was taken into consideration. During the Italo-Turkish War of 1911, the Ottomans had to admit their disadvantage of not possessing an air force. Subsequently, the Ottomans employed German and French engineers who helped them to establish an air force with a dozen airplanes. The Ottoman Aviation Squadrons participated in the Balkan Wars (1912–1913) and World War I (1914–1918). The fleet size reached its apex in December 1916, when the Ottoman Aviation Squadrons had 90 active combat aircraft. Some early help for the Ottoman Aviation Squadrons came from the Imperial German Fliegertruppe (known by that name before October 1916), with future Central Powers 13-victory flying ace Hans-Joachim Buddecke flying with the Turks early in World War I as just one example. By July 1918, the Aviation Squadrons were reorganized as the General Inspectorate of Air Forces . (Kuva-yı Havaiye Müfettiş-i Umumiliği).
After the Armistice of Mudros and the occupation of the Ottoman Empire by the Allies in 1919, some Turkish aviators tried to build new units in Istanbul, İzmir, Konya, Elazığ and Diyarbakır with planes left over from World War I and tried to bring together flight personnel. During the Turkish War of Independence, Turkish pilots joined the Konya Air Station (Konya Hava İstasyonu). With the formation of the Grand National Assembly (GNA) by Mustafa Kemal and his colleagues on 23 April 1920, in Ankara, and the reorganization of the army, the Branch of Air Forces (Kuva-yı Havaiye Şubesi) was established under the Office of War (Harbiye Dairesi) of the GNA. A few damaged aircraft belonging to the GNA were repaired, and afterwards used in combat.
In July 1922, it was reorganized as the Inspectorate of Air Forces (Kuva-yı Havaiye Müfettişliği) at Konya.
After the establishment of the Republic of Turkey on 29 October 1923, plans were made to form a modern air force. Originally consisting of three normal and one naval aviation units, and an air school, the number of units was increased to 10 normal and three naval aviation units. Starting in 1924, personnel were sent abroad for flight education. In 1925, the Air School was re-established in Eskişehir and its first students were graduated that same year. In the same year, the Air Force was deployed to take part in a campaign aimed to suppress the Sheikh Said rebellion. The Inspectorate of Air Forces was reorganized as the Undersecretariat of the Ministry of Defense in 1928 and new schools were found for non-pilot personnel. Some personnel were sent to the United Kingdom and France for training; others were sent to the United States and Italy in 1930.
From 1932, the air regiments were considered to be a separate combat arm and started training its own personnel. Turkish aviators wore blue uniforms from 1933.
The Air War College (Hava Harp Akademisi) was established in 1937.
By 1940, Turkish air brigades had more than 500 combat aircraft in its inventory, becoming the largest air force in the Balkans and the Middle East. The growing inventory of air brigades required another structural change, which was made in 1940. The Air Undersecretariat under the Ministry of National Defense for logistical affairs and the General Staff for educational affairs were united to form the Air Force Command (Hava Kuvvetleri Komutanlığı) in 1944. Thus, the Air Force became a separate branch of the Turkish Armed Forces. The first Commander of the Turkish Air Force was General Zeki Doğan. Turkey did not enter World War II on the side of the Allies until February 1945. However, the Turkish Armed Forces went on full alert and were prepared for war following the military alliance between neighbouring Bulgaria and the Axis Powers which was formalized in March 1941, and the occupation of neighbouring Greece by the Axis Powers in April 1941. Within a year, Turkey's borders were surrounded by German forces in the northwest and west, and Italian forces in the southwest. The Turkish Air Force made daily reconnaissance flights over Bulgaria, Greece, the Greek Islands in the Aegean Sea, and the Dodecanese Islands which then belonged to Italy, to monitor the positions of the Axis forces. The large cities in western Turkey were darkened at nights, and anti-aircraft guns and searchlights were deployed for defence against possible enemy planes. The Turkish Government Treasury was used to purchase new weapons from any available provider in the world. The Turkish Air Force received large numbers of new aircraft in this period, including Supermarine Spitfire Mk.I/V/IX/XIX, Curtiss Falcon CW-22R/B, Fairey Battle-I, Avro Anson-I, Hawker Hurricane I/II, Morane-Saulnier M.S.406, Curtiss P-40 Tomahawk, Curtiss P-40 Kittyhawk, Westland Lysander-I, Consolidated B-24D Liberator B-24, Bristol Blenheim IV/V, Bristol Beaufort, Bristol Beaufighter Mk.I/X, Focke-Wulf Fw 190-A3, Martin 187 Baltimore, De Havilland DH.98 Mosquito Mk.III/IV, Douglas B-26B/C Invader, P-47D Thunderbolt and Douglas C-47A/B Dakota.
The Air Machinist School (Hava Makinist Okulu) was reorganized as Aircraft Maintenance School (Hava Uçak Bakım Okulu) on 2 January 1950 to unite schools responsible for training non-pilot Air Force personnel. In 1950 it also was decided to upgrade the Air Force fleet through the inclusion of jets. Eight pilots were sent to the United States for jet pilot training. They graduated in 1951 and started training jet pilots in the Turkish Air Force. In the same year, the 9th Fighter Wing (9’uncu Ana Jet Üssü) was founded in Balıkesir as Turkey's first fighter wing; the 191st, 192nd, and 193rd squadrons being the first ones which were established. Further training in the United States followed, usually involving jet manufacturers. In 1951 the Air Force Academy was formed with integrating some air schools in Eskişehir and its first academic year started on 1 October 1951. In 1956 the Hava Eğitim Kolordu Komutanlığı (Air Education Corps Command) was founded and all education was united under this command. The command was renamed as Hava Eğitim Komutanlığı (Air Education Command) in 1957.
Upon Turkey's membership to NATO in 1952, the process of modernization was accelerated. In 1962 the Taktik Hava Kuvveti (Tactical Air Force) was founded by upgrading the Hava Tümeni (Air Division) units to corps-level organizations.
In 1972, the force underwent major reorganization. The roundel was changed, the fleets were rebuilt and propelled airplanes were phased out in favour of jet-powered ones.
In 1974 the Air Force was employed during the Turkish invasion of Cyprus. With the arrival of the first batch of 40 third generation F-4E Phantom II fighter jets ordered in 1972 and acquired between 1974 and 1978, the Air Force was reorganized. This was followed by a second order in 1978 of another batch of 40 units (32 F-4Es and 8 RF-4Es, deliveries began in 1980). Another order for 70 more F-4Es were acquired between 1981 and 1987, and 40 more F-4Es were acquired between 1991 and 1992, as well as 46 more RF-4E reconnaissance aircraft. In total, the Turkish Air Force received 236 F-4 Phantom II (182 F-4E and 54 RF-4E) aircraft. In 1997, IAI (Israel Aircraft Industries) was selected to upgrade 54 of Turkey's F-4E fighter aircraft to the F-4E Terminator 2020 standard. The upgraded aircraft were delivered between 1999 and 2003; of these, 26 aircraft were upgraded in Israel and the remaining 28 were upgraded in Turkey.
