Turkish Aerospace Industries

Turkish Aerospace Industries Inc. (Turkish: Türk Havacılık ve Uzay Sanayi A.Ş., abbr. TAI or TUSAŞ) is a state-owned arms company in Turkey.
On 16 August 1925 the Turkish Aircraft and Engine Limited Company (Turkish: Tayyare ve Motor Türk Anonim Şirketi, TOMTAŞ) factory was founded in Kayseri, Turkey. The company received its current name in 1973 and was incorporated into the Ministry of Industry and Technology of Turkey to reduce the "foreign dependence" of the country's defense industry.
Their first project was to make the new F-16 from the US ready for the Turkish Air Force. In 1984 the US companies Lockheed Martin and General Electric joined in, with TAI producing its first F-16 in 1987. TAI produced 240 F-16 aircraft for Turkey and assembled 46 F-16s for the Egyptian Air Force in the 1980s and 1990s. Because of disagreements, TUSAŞ was not very active in the time span from 1984 to 2005.
In 2005 Turkish private persons and Turkish companies bought the shares of Lockheed Martin and General Electric. The new owner agreed to put the company back under control of the Turkish state.
On 23 October 2024 an attack was launched on the company's offices in Kahramankazan, Ankara Province, leaving five people dead and 22 others injured. The two perpetrators of the attacks were also killed. Later, the PKK admitted to committing the assault.
TAI's experience includes the licensed production of General Dynamics F-16 Fighting Falcon jets, CASA/IPTN CN-235 light transport/maritime patrol/surveillance aircraft, SIAI-Marchetti SF.260 trainers, Cougar AS-532 search and rescue (SAR), combat search and rescue (CSAR) and utility helicopters as well as the design and development of Unmanned aerial vehicles (UAVs), target drones and agricultural aircraft.
TAI's core business also includes modernization, modification and systems integration programs and after sales support of both fixed and rotary wing military and commercial aircraft that are in the inventory of Turkey and its allies.
TAI's Hürkuş basic trainer aircraft has been granted air worthiness type certification, the company announced at the 2016 Farnborough International Airshow.
Turkish Aerospace/TUSAS produced 46 F-16s for the Egyptian Air Force between 1993 and 1995 under the agreement signed between the Governments of Turkey and the Arab Republic of Egypt. A contract to produce 46 Block 40 F-16C/D's for the Egyptian Air Force was placed with TUSAS Aerospace Industries (TAI) of Turkey. 34 of them will be F-16C's, 12 will be F-16D's. This was carried out under the auspices of the Peace Vector IV program, and marked the first sale of a foreign-built Fighting Falcon to a third-party nation in the history of the F-16 program.
TAI is engaged in manufacturing aerostructures for fixed and rotary wing, military and commercial aircraft for worldwide customers. TAI is in various partnership arrangements with AgustaWestland, Airbus, Alenia Aermacchi, Boeing, IAI, Lockheed Martin, Northrop Grumman, MD Helicopters, Sikorsky, Indonesian Aerospace and numerous other companies in aerospace sector.
TAI manufactures Section 18 fuselage panels for Airbus 319/320/321 aircraft, wing tips and flight deck panels for Boeing 737 aircraft, rear doors and engine cowlings for Eurocopter EC135 helicopters, MD 902 fuselage for MD Helicopters, horizontal stabilizers, tail rotor pylons and tail booms for Sikorsky S-70A and MH-60 helicopters, horizontal stabilizers for Sikorsky S-76 helicopters and AB139 fuselages for Agusta. Furthermore, TAI manufactures nose landing gear doors for the Boeing 747, dorsal fin for 777 and parts/subassembly parts for 737/767/777. It also manufactures seven components of the Eurocopter AS 532 helicopter.
TAI, which had a single program (the co-production of the F-16 Fighting Falcon) at its establishment phase, is working on over 50 military and commercial programs today. As a partner of the Airbus Defence and Space, TAI has been participating in the design and development activities of the Airbus A400M program with the leading European aerospace companies; namely Airbus (France, Germany, Spain and UK), EADS CASA (Spain) and FLABEL (Belgium) from the beginning of the project. TAI has accepted the production of A350XWB's winglets with the new cooperation.
In May 2015 the Turkish regional jet project was launched, which consisted of the indigenous production of two regional aircraft in different sizes. The 32-seat TRJ-328 jet with a range up to 2,000 nmi (2,300 mi; 3,700 km) was planned to enter service in 2019. It was a Fairchild Dornier 328JET-based, modernized aircraft with new cockpit and engines. The larger, 70-seat TRJ-628 jet would be ready in 2023. The project has since been cancelled.
In June 2024 news media reported that TAI was responsible for introducing questionable titanium into the supply chain for aircraft parts which ultimately were used to manufacture some Boeing and Airbus passenger planes built between 2019 and 2023. The titanium sold by TAI included falsified authenticity documentation that originated from a metals supplier in China, calling into question whether the titanium was truly aviation-grade. However, Spirit's testing has confirmed that the titanium is the appropriate grade for airplane manufacturers.
TAI operates Turkish Satellite Assembly, Integration and Test Center.
