Turkish Aerospace, TUSAŞ and TAI: are they the same company?

Turkish Aerospace, TUSAŞ and TAI are the same company: TUSAŞ (Türk Havacılık ve Uzay Sanayii A.Ş.) is the legal name in Turkish, while Turkish Aerospace and its acronym TAI are the brand in English. On the other hand, TUSAŞ is not TEI: TEI is an independent engine company, although related.

Why are TUSAŞ, TAI, and Turkish Aerospace the same company?
Name confusion is common, but the answer is simple: it is a single company with different names. TUSAŞ is the legal name in Turkish, an acronym for Türk Havacılık ve Uzay Sanayii Anonim Şirketi. Turkish Aerospace is the trademark in English under which the company presents itself internationally, and TAI is its acronym (Turkish Aerospace Industries / Turkish Aerospace Inc.). The history explains the coexistence of names: TUSAŞ was founded on June 28, 1973 as an industrial organization to create a national aerospace base. In 1984, a Turkish-American joint venture was established under the name Turkish Aerospace Industries (TAI), created for the assembly and licensed production of the F-16 fighter jet. For years, two related entities coexisted until in 2005, TAI and TUSAŞ merged into a single company under the name Türk Havacılık ve Uzay Sanayii A.Ş. (Turkish Aerospace Inc.). Since then, all those names refer to the same company.

Which name should I use?
Any of them is correct, depending on the context. Here are the keys to avoid mistakes:
- TUSAŞ: is the official name in Turkish; it is used in legal documents, Turkish press, and internal communications.
- Turkish Aerospace: is the international brand; it appears at fairs, export contracts, and its website in English.
- TAI: is the acronym in English, commonly used in specialized media and defense analysis.
- All point to the same: the Turkish aerospace company based in Kahramankazan (Ankara), prime contractor of the KAAN fighter jet, ANKA drones, and GÖKBEY helicopters.
- Be careful with TEI: do not confuse with TEI, which is another company (engines), as explained below.
To understand the evolution of the names, it is advisable to follow the chronology of the company. The following table summarizes how it transitioned from two related entities to a single company with various names.

Regardless of the name used, it is one of the largest defense companies in the world. The following data, taken from the Defense News Top 100 ranking and corporate information, refer to the same company (TUSAŞ = Turkish Aerospace = TAI).
TUSAŞ is not TEI: what is the difference?
This is the most common mistake. TUSAŞ (Turkish Aerospace) and TEI (TUSAŞ Engine Industries / TEI Motor Sanayii) are two distinct companies, although they are related. TUSAŞ manufactures complete platforms: airplanes, helicopters, drones, and satellites. TEI is dedicated to aerospace engines and is an independent firm in which TUSAŞ is a shareholder, but they are not the same company. The distinction is key to understanding programs like the fighter KAAN or the trainer HÜRJET: TUSAŞ is the prime contractor for the aircraft, while the engine comes from suppliers like TEI or foreign manufacturers. In the case of the KAAN, the prototypes fly with two American GE F110 engines; the national design engine is still a goal of the program and is not ready. Therefore, when it is read that “TUSAŞ develops the KAAN,” it refers to the airframe and integration, not the engine, which belongs to another company.
Relationship with other defense companies
In addition to TEI, TUSAŞ works as a prime contractor and integrator alongside other companies in the Turkish ecosystem, each with its role: ASELSAN provides radars, avionics, electro-optical systems, and electronic warfare; HAVELSAN handles software and simulation; and ROKETSAN along with TÜBİTAK SAGE supply missiles and munitions. Thus, a “TUSAŞ platform” actually integrates subsystems from various companies. Recognizing these boundaries prevents attributing products to TUSAŞ—such as engines or radars—that are actually manufactured by partner companies.
TUSAŞ, Turkish Aerospace, and TAI are the same company. TEI, on the other hand, is a distinct engine company (TUSAŞ is a shareholder, not the same company). Prototype data does not equate to series values, and the goal of a national engine does not equate to a ready engine; what is not officially confirmed should be treated as “not officially disclosed.”
Frequently Asked Questions
What does TAI mean?
TAI is the English acronym for Turkish Aerospace Industries, now Turkish Aerospace Inc. It is the international designation of TUSAŞ, the Turkish aerospace and defense company based in Kahramankazan (Ankara). It is mainly used in specialized media, international fairs, and export contracts, but it designates exactly the same company as TUSAŞ.
Is TAI the same as TUSAŞ?
Yes. TUSAŞ is the legal name in Turkish (Türk Havacılık ve Uzay Sanayii A.Ş.) and TAI / Turkish Aerospace is its brand in English. Although there were historically two related entities, they merged in 2005 into a single company. Today, TUSAŞ, TAI, and Turkish Aerospace are three names for the same company.
Is TUSAŞ the same as TEI?
No. TEI is a distinct company dedicated to aerospace engines (TUSAŞ Engine Industries). TUSAŞ is a shareholder of TEI, but they are not the same company. TUSAŞ manufactures complete platforms —aircraft, helicopters, drones, and satellites— while TEI produces engines. It is a common mistake to confuse the two due to the similarity of the acronyms.
Why does the company have two names?
Due to its history and international projection. TUSAŞ is the Turkish legal name, while Turkish Aerospace (TAI) is the English brand used outside of Turkey. Additionally, TAI was established in 1984 as a joint venture and merged with TUSAŞ in 2005. Since then, both names coexist for the same company, depending on the language and context.
What was the previous name of the company?
The name Turkish Aerospace Industries (TAI) was adopted in 1984 for the Turkish-American joint venture created to produce the F-16 fighter. After the 2005 merger, the legal name became Türk Havacılık ve Uzay Sanayii A.Ş. (Turkish Aerospace Inc.). The acronym TAI is retained as the international brand.
Who manufactures the engine of the KAAN fighter?
The engine is not manufactured by TUSAŞ. The prototypes of the KAAN fly with two American GE F110 engines. For serial production, a national design engine is being pursued, which is being worked on by TEI, a distinct engine company from TUSAŞ. That national engine is still a goal of the program and is not yet ready or certified.
Do TUSAŞ and Turkish Aerospace have the same headquarters?
Yes, because they are the same company. Both TUSAŞ and Turkish Aerospace (TAI) have their headquarters in Kahramankazan, in the Ankara province (Turkey). There, their main design, production, integration, and flight testing facilities are concentrated for programs such as the KAAN, ANKA, or GÖKBEY.
