Development

Summarize
Perspective

On 15 December 2010, Turkey's Defence Industry Executive Committee (SSIK) decided to design, develop, and manufacture a national next generation air-superiority fighter which would replace Turkey's F-16 fleet and operate with other critical assets like the F-35 Lightning II.[16]

In 2011, Turkey's Undersecretariat for Defence Industries (SSM), now known as the Defence Industry Agency, the procurement agency for the Turkish Armed Forces, signed an agreement with TAI for the conceptual development of basic capabilities. TAI and TUSAŞ Engine Industries (TEI) would lead the design, entry, and development processes of the fighter jet. The studies would reveal the cost of the fighter, while investigating which mechanical and electronic systems would be employed and included, and a wider perspective of the opportunities and challenges in military aviation.[17] Funding equivalent to US$20 million was allocated for a 2-year conceptual design phase performed by the Turkish Aerospace Industries.[18] TAI officials stated that conceptual design phase should be complete in late 2013, with a report being prepared and submitted to the Prime Minister for the approval of development phase budget and framework. Janes has described the project as "extremely ambitious".[19]

On February 15, 2024, Ukraine has expressed interest to acquire the Kaan.[20]

Design choice

In 2015, the TAI released three potential airframe configurations:

Turkish Prime Minister Ahmet Davutoğlu announced on 8 January 2015, that the TF-X will be a twin-engined fighter.[8] The Undersecretariat for Defence Industries published its 2016 Performance Report in March 2017, where it was revealed that the final decision was to continue with the twin engine FX-1 configuration.[22][23]

Bid

On 13 March 2015, the Turkish Undersecretariat for Defence Industries (SSM) officially issued a Request for Information to Turkish companies which had the capability "to perform a genuine design, development and production activities of the first Turkish fighter aircraft to meet Turkish Armed Forces' next generation fighter requirements" signalling the official start of the program.[24] The contract for design and development of the fighter was signed between the SSM of Ministry of Turkish National Defence and Turkish Aerospace Industries Inc. on 5 August 2016. The SSM granted $1.18 bn. to Turkish Aerospace Industries to acquire necessary technologies and infrastructure for the design, testing and certification of the aircraft.[25] In the same period, Request for Proposal was published for the engine of the aircraft, and General Electric, Eurojet and Snecma companies returned to this file. Within the scope of the RFP, the condition was for the engine infrastructure to be developed in Turkey and production be domestic as long as possible.

Former partnership plans and proposals

Saab AB

In February 2013, meetings were held with Saab AB upon the instruction of then-Prime Minister Recep Tayyip Erdoğan, and an agreement was signed between TAI and the Swedish firm Saab during the state visit of then-Turkish President Abdullah Gül to Sweden on 13 March 2013, according to which:[26]

  • Saab AB would provide technological design assistance for Turkey's TF-X program.
  • TAI would have the option to purchase Saab's fighter aircraft design unit.

This plan was later abandoned and on January 8, 2015, then-Prime Minister Ahmet Davutoğlu announced that the TF-X program will be a completely independent domestic platform, not in partnership with Korea, Sweden, Brazil or Indonesia.

Cooperation agreement between TAI and BAE Systems

In December 2015, Turkey's Undersecretariat for Defence Industries (SSM) announced that it had chosen BAE Systems of the United Kingdom to assist with the design of the nation's next-generation air superiority fighter. On the same day, Rolls-Royce offered technology transfer for the EJ200 engine and joint-development of a derivative for the TF-X program.[27] During the visit of British Prime Minister Theresa May to Turkey in January 2017, BAE Systems and TAI officials signed an agreement, worth about £100 million, for BAE Systems to provide engineering assistance in developing the aircraft.[28] Following the agreement, the UK issued an open general export licence to defence companies willing to export goods, software or technology to Turkey.[29]

Engine

On 20 January 2015, ASELSAN of Turkey announced that it had signed a memorandum of understanding with Eurojet, the manufacturer of the EJ200 engine used in the Eurofighter Typhoon.[30] The announcement also stated that a derivative of the EJ200 will be used in the TF-X program.[31][32][33][34] The two companies will additionally collaborate and co-develop engine control software systems and engine maintenance monitoring systems.[34] Turkey's selection of the EJ200 evidenced TAI's intention to use supercruise capability. In May 2017, Rolls-Royce established a joint venture with the Kale Group of Turkey to develop and manufacture engines for the project.[35] Another competitor is TRMotor Power Systems Inc. established in April 2017 by BMC, TAI and SSTEK. On 8 November 2018, TRMotor signed a memorandum of understanding with the Presidency of Defence Industries to develop a jet engine for the TF-X project.[36]

While General Electric did not openly express interest in the TF-X project, its local partner Tusaş Engine Industries (TEI) announced that it will participate in the engine development phase. On 11 June 2018, TEI General Manager Mahmut Faruk Akşit said that they proposed a mature engine for which they had completed a commercial proposal for the infrastructure of sub-component tests for the compressor. He emphasized the advantage of GE engines over its competitors stating that they have significant OEM support whereas the collaboration between other companies were yet to thrive. TEI committed to submit all intellectual rights to the government.[37] In October 2018, local media reported that an unknown number of initial production fighters will be equipped with General Electric F110 engines until Turkish Air Engine Company (TAEC)[38] finalizes the local engine.[39]

On 14 March 2022 Kale & Rolls-Royce re-started the progress of developing an engine for the TF-X program, stating that the previous disputes between the companies have been resolved and that the first prototypes of the TF-X will use the F110 engine.[40]

On 5 March 2022, İsmail Demir, undersecretary for Defence Industries, said the government would now negotiate a possible engine deal with Rolls-Royce. “We had some issues [with Rolls-Royce] before. These have been resolved. I think we are ready to work together.”[41]

In May 2022, while visiting the U.K., Demir said, "It is imperative for us that the engine be produced in Turkey… that Turkey should possess intellectual property rights."[42] His statement implied that the same dispute over intellectual properties of the engine which previously stalled the negotiation between Rolls-Royce and Turkey in 2019[43] remained unresolved.

As of 2 June 2022, unknown number of General Electric F110 engines delivered to TEI as the first batch according to the agreement between Tusaş Engine Industries (TEI) and GE Aerospace that comprises delivery of 10 engines in total.[44][45]

On 2 July 2022, the Defence Industry Agency published the invitation to tender for the domestic development of the engine to be used and İsmail Demir, undersecretary for Defence Industry Agency, stated that TRMotor, which is a subsidiary of TAI, has submitted its proposal and Turkish Air Engine Company (TAEC), consortium by Kale Group and Rolls-Royce, will submit its offer soon.[46]

Development schedule overview

Development Phase-1 was expected to officially commence by the end of 2014,[47] however, initial conditions were met and the project has officially started in late 2018.

On June 30, 2021, the Turkish Air Force made an official presentation about the TF-X program to the press. In the presentation, it was stated that Phase-1 Stage-1 had started with preliminary design works, right after T0 stage. As part of preliminary design activities, a system requirements review (SRR) is currently being carried out. By the end of 2022, system functionality review (SFR) and system requirements review (SRR) will be completed. Thus, the preliminary design activities will come to an end. The program is expected to go to the next stage by 2023 when the initial roll-out occurs with engines capable of taxiing.[1]

Phase-1 Stage-2 involves detailed design and qualifications carried out in the 2022-2029 period. The aircraft will roll out in 2023, critical design review (CDR) activities will be carried out in 2024, the production of the first aircraft, called Block-0, will be completed in 2025 and the first flight will be accomplished in 2026. Until that date, TAI aims to manufacture 3 prototypes.[1] The Block-1 configuration is planned to be developed until 2029. The manufacture of 10 Block-1 fighter jets is planned within the scope of Phase-2, and the aircraft will be delivered to the Turkish Air Force between 2030 and 2033.[1] In Phase-3, between 2034 and 2040, development and mass production activities of other TF-X blocks is planned.[1]

Start of production

On November 4, 2021, the first piece of MMU was manufactured. Temel Kotil, CEO of TAI said;

We have realized the production of the first part of our National Combat Aircraft. Every step we take for the survival project of our country is very meaningful and valuable for us. I would like to thank all my friends with whom we walked on the same path by working with enthusiasm and effort.[48]

The other 20,000 parts of TF-X were planned to be ready by the end of 2022.[49]

TAI's Deputy General Manager responsible for TFX Dr. Uğur Zengin, stated on February 11, 2022, that 550 parts of TF-X were in production.[50] The maiden flight was planned for 2025,[51] but has been rescheduled for the end of 2023.[52]

The aircraft was officially named Kaan on May 1, 2023.[53][54][55]

In May 2023, TAI CEO Temel Kotil said the company expects to deliver twenty Block 10 aircraft to the Turkish Air Force in 2028, then two aircraft per month by 2029, generating $2.4 billion in annual revenues for TAI.[56]

Kotil also warned that the price tag of the aircraft may surpass his 2021 promise of $100 million per unit.[56] This led the company to seek additional capital and production workers. In July 2023, at the 16th International Defense Industry Fair, a protocol agreement was signed to bring Azerbaijan into the project. Project officials began looking for Azerbaijani companies and production facilities that could be used and 200 Azerbaijani workers were to be immediately dispatched to join the fighter project.[57]

On February 21, 2024, Kaan conducted its maiden flight. TAI shared a video showing a KAAN fighter jet taking off and then returning to Mürted Airfield Command in the north Ankara.[58]

Hüseyin Yağcı, TAI's chief engineer on the TF-X program, has stated that all three conceptual designs thus far feature a design optimized for low radar cross-sectional density, internal weapons bays, and the ability to supercruise, features associated with fifth-generation fighter jets.[9]

TAI's Advanced Carbon Composites fuselage facility, which was commissioned to produce fuselages for Lockheed Martin's Joint Strike Fighter (F-35) program,[59][60] has been tasked with developing an Advanced Carbon Composite fuselage for the TF-X. The Turkish Defence Industry Agency has also issued a tender for the development of a new lighter carbon composite thermoplastic for the TF-X fuselage.[61]

Prototypes and the first batch of aircraft will be equipped with General Electric F110 engines. TR Motor collaboration with TEI will develop locally made engines for the aircraft, which will produce at least 36.000 pound of thrust. Locally developed engines are planned to be integrated and tested on the aircraft in 2029-2030.[67]

Future operators

 Turkey (at least 20)
According to TAI executives, the company will supply at least 20 KAAN by 2028.[68]

Potential operators

 Malaysia
Turkey is offering the KAAN to the Malaysian Air Force as part of the MRCA programme.[69]
 Saudi Arabia (100)
As Saudi Arabia hasn't been allowed to purchase the Lockheed Martin F-35 Lightning II (5th generation fighter), the air force is looking for a stealthy alternative as a stop-gap until the arrival of 6th generation fighters on the market. The KAAN is one of the options considered with a purchase of 100 fighters.[70]
 Pakistan

Pakistan and Turkey have established a joint collaboration for the production of the KAAN fifth-generation fighter jet. However, the exact number of KAAN jets that Pakistan plans to acquire has not been publicly disclosed.

Additionally, Pakistan is exploring other options, such as acquiring the Chinese Shenyang J-35 fighter jet and developing its own fifth-generation fighter under "Project Azm." So, while Pakistan is likely to acquire KAAN jets, the final number remains uncertain.
