Are TUSAŞ and TAI the same company?
Yes, TUSAŞ and TAI are the same company; they are two different names for a single organization in different languages. TUSAŞ is the abbreviation of the company’s Turkish title, Türk Havacılık ve Uzay Sanayii Anonim Şirketi. TAI, on the other hand, is the abbreviation of the company’s English brand name, Turkish Aerospace Inc.. While “Turkish Aerospace” or “TAI” is used in international fairs and English publications today, “TUSAŞ” is preferred within Turkey and in Turkish documents. The two abbreviations are sometimes written together (TUSAŞ/TAI). The source of the confusion is historical: there was indeed a separate legal entity that carried the name “TAI” in the company’s past. However, these two entities were merged in 2005; therefore, when TUSAŞ and TAI are mentioned today, it refers to the same and single company.
Why are there two names? History
The reason for the coexistence of the two names is the company’s founding and merger history. The stages are as follows:
- 1973 — TUSAŞ was established to reduce Turkey’s dependence on foreign aviation.
- 1984 — TAI (Turkish Aerospace Industries), a separate company for the licensed joint production of F-16 fighter jets, was established; this was a 25-year joint investment involving Turkish entities and American partners.
- 2000s — The Turkish side gradually took over foreign shares.
- 2005 — TAI and TUSAŞ were merged under a single roof as “Türk Havacılık ve Uzay Sanayii A.Ş.”
- Today — The Turkish abbreviation TUSAŞ and the English abbreviation TAI; both refer to the same company.
The table below summarizes the changes in the company’s name and identity over time. This timeline shows why the names “TUSAŞ” and “TAI” are used interchangeably.
TUSAŞ/TAI is not publicly traded; its capital is held by Turkish public institutions. The table below summarizes the company’s current corporate and financial position.
Is TUSAŞ the same company as TEI? (IMPORTANT distinction)
No. The most common confusion to note here is: TUSAŞ and TEI are not the same company. TEI (TUSAŞ Engine Industries / TP Aircraft Engine Industry Inc.) is a separate organization based in Eskişehir that develops and produces aircraft engines. It is often mistaken for the same company because “TUSAŞ” is in its name and TUSAŞ is one of its partners; however, TEI is an independent company with its own legal identity. TUSAŞ is the platform prime contractor: it designs the airframe of the aircraft, helicopter, or UAV, integrates the systems, and conducts flight testing. The engines come from TEI and foreign suppliers. For example, the national combat aircraft KAAN prototype flies with two General Electric F110 engines; the domestic engine is a goal and is not yet ready. A domestic TEI TS1400 engine is also being developed for the general-purpose helicopter GÖKBEY. In short, the aircraft and helicopter airframes are TUSAŞ’s responsibility, while the engines are TEI’s (and foreign manufacturers’).
Role differentiation with other companies
TUSAŞ/TAI is not the manufacturer of every subsystem in the platforms it produces; there is a division of labor in Turkey’s defense ecosystem. Radar, avionics, electro-optical, and electronic warfare systems largely come from ASELSAN. Engines are supplied by TEI and foreign manufacturers. Software and simulation work involves HAVELSAN. Ammunition and guided weapons are produced by ROKETSAN and TÜBİTAK SAGE. This division of labor shows that TUSAŞ designs and integrates the aircraft as a whole, while specialized partners provide the specific systems within it. Therefore, not all parts of a platform referred to as a “TUSAŞ product” belong to TUSAŞ.
TUSAŞ and TAI are the Turkish and English names of the same company. In contrast, TUSAŞ and TEI are separate entities: TEI produces aircraft engines, while TUSAŞ is the platform prime contractor. The KAAN prototype flies with a foreign GE F110 engine; the domestic engine is a goal and is not ready.

The company’s origins date back to TUSAŞ, which was established in 1973. The separate entity established in 1984 for F-16 production was named Turkish Aerospace Industries (TAI). After the merger in 2005, the company adopted its current official title, “Türk Havacılık ve Uzay Sanayii A.Ş.”; its English brand was updated to Turkish Aerospace Inc.
Is there a difference between Turkish Aerospace and TUSAŞ?
No, there is no difference. “Turkish Aerospace” is the English name of the company and refers to the exact same organization as TUSAŞ. While Turkish Aerospace or simply TAI is used in English publications and international promotions, TUSAŞ is preferred in Turkish. Both refer to the same company based in Kahramankazan, Ankara.
What engines does TUSAŞ use?
TUSAŞ platforms obtain their engines from TEI and foreign manufacturers. For example, the KAAN prototype flies with two General Electric F110 engines, while the HÜRJET flies with an F404 engine. A domestic TEI TS1400 engine is being developed for the GÖKBEY helicopter. A fully domestic combat aircraft engine is still in the target phase; it is not ready for mass production.
