Why not newer F414? I hope TEI would built them..
I still prefer EJ200 if it would be build by Kale Rolls-Royce, small batch of Typhoons to replace F4s and locally build EJ200s.

International outreach by GE for other (non US) countries platforms I think.
Other categories are all essentially US-based platforms etc (either US or another country operates it).

It is an international project with US engine and some other country's airframe and also that airframe is indigenous to that other country. International only means involving more than one country and does not necessarily mean the product is made for more than one country.

İ wish we were on the position where we could pick up from a lot of alternatives but unfortunately...
It looks like the share has been removed.View attachment 15398 View attachment 15399
Hard work and endless efforts with a great deal of team work finally paid off, resulting over 1700 pages of a critical design report. I feel like as if we have achieved to write a book called "introduction to trainer jet aircraft design&built 101". I am very proud to be a member of this magnificant team. Well done to all who is involved.

Too powerful for the design of a mere trainer and (perhaps) a light attack variant.

The good news is "Hurjet engine has been selected"
HÜRJET New Generation AJT’s CDR Phase Completed
The Critical Design Review (CDR) Phase of the HÜRJET, twin-seat, single-engine supersonic new generation Advanced Jet Trainer (AJT) and Light Combat Aircraft (LCA) was completed in early March 2021. According to original schedule the CDR Phase should have been completed in August 2020 (To+36 months).
Speaking at a ceremony organized at TUSAŞ facilities to celebrate the delivery of first T129B2 ATAK Helicopter to the Security General Directorate (Turkish Police) on February 26, 2021 TUSAŞ President & CEO Temel KOTİL disclosed that HÜRJET prototype will perform its maiden flight in December 2022, after the completion of the detailed design, prototype production and ground testing phases. While talking to TRT Radio 1 at the National and Domestic Program on December 4, 2020 TUSAŞ President & CEO KOTİL had previously underlined that the first HÜRJET prototype would execute its maiden flight on March 18, 2023, when the 108th anniversary of the Çanakkale Naval Victory will be celebrated.
HÜRJET is being developed by TUSAŞ under a Protocol signed between TUSAŞ, the SSB and the TurAF on July 2, 2018. The initial studies for the “Advanced Jet Trainer & Light Attack Aircraft (HÜRJET) Project” were started in July 2017 and the Project was officially launched on 14 August 2017, as a company funded project (which was funded from TUSAŞ’ own resources) after receiving a green light to go ahead from the TUSAŞ Board.
The Conceptual Design Phase (CDP) of the HÜRJET Project was completed in April 2018, according to original schedule the Preliminary Design Review (PDR) Phase activities should have been completed in February 2019 (To+18 months), Critical Design Review (CDR) Phase should have been completed in August 2020 (To+36 months) and the Test Readiness Review (TRR) Phase should have been completed in August 2021 (To+48 months). However due to the internal and external reasons this schedule could not be kept. The PDR Phase could only be completed in July 2020. Within the scope of the PDR Phase, TUSAŞ engineers have carried out several wind tunnel tests including Static Wind Tunnel Tests, Air Intake Wind Tunnel Test and Low Speed Wind Tunnel Test with HÜRJET’s 1/10 scaled model to confirm the existing configuration. The HÜRJET model that underwent the initial wind tunnel tests was configured in accordance with GE’s F404-GE-102 turbofan engine.
Following the signing of a Letter of Intent (LoI) between TUSAŞ and Eurojet Turbo GmbH for the delivery of EJ200 turbofan engines the design of the HÜRJET was modified (such as, the air intakes were revised and enlarged to accommodate the more powerful EJ200 engine) and further wind tunnel tests have been carried out to confirm revisions on the aircraft overall design. So currently HÜRJET has two separate designs in accordance with two different engine options. According to our sources the HÜRJET will be powered by the F404-GE-102 engine from GE. Under the project two prototypes will be manufactured. According to project schedule the 1st HÜRJET prototype would be rolled-out in December 2021 and to perform its maiden flight in February 2022 (To+60 months), the 2nd HÜRJET prototype, on the other hand, is planned to perform its maiden flight in August 2022 (To+64 months) but this schedule seems to could not be accomplished.
The HÜRJET Project is aimed at the development of an indigenous new generation Advanced Jet Trainer (AJT), capable of supersonic flight to replace the T-38M jet trainer fleet in the service of the TurAF in 2030s, and a Light Combat Aircraft (LCA) able to perform a Close Air Support (CAS) role to assist and release the load off the TurAF’s F-16C/Ds shoulders. The indigenous jet trainer HÜRJET will be utilized to train and prepare pilots for the next generation MMU/TF aircraft in the 2030s, replacing the aging T-38M jet trainers in service with the TurAF. Currently the TurAF operates 68 T-38M Advanced Jet Trainers in Advanced Jet Training and Combat Readiness Transition Training at Çiğli Air Base (2nd Main Jet Base Command) in Izmir.
As a clean-sheet design the single-engine, twin-seat HÜRJET will be Turkey’s first indigenous supersonic aircraft and one of the world’s few supersonic trainers. The aircraft is 13m (42.6ft) in length, 4.2m (13.7ft) in height, has a 9.8m (32.1ft) wingspan and 24m2 (258.33 sq ft) wing area. The figures related the predicted empty weight and maximum takeoff weight (MTOW) of the aircraft have not been publicized yet. HÜRJET prototypes will be powered by GE’s 17,000lb thrust class F404-GE-102 turbofan engine. Also, a number of series productions of HÜRJET were also planned to be powered by F404 turbofans (supposed to be manufactured by TEI under license in Turkey). According HÜRJET’s publicised Technical Specification, the maximum speed of the HÜRJET will be Mach 1.4; the service ceiling will be 13.716m (45,000ft) and the climb rate will be 39,000ft/minute. The HÜRJET will be able to perform +8G/-3G maneuvers and will be capable of sustaining 5.5Gs at an altitude of 15,000ft and up to Mach 0.9 speed. The range of the aircraft will be 2,222km (1,200nm) and payload capacity will be 2.721kg (6.000lb).
As Turkey’s first indigenously developed supersonic aircraft the HÜRJET will pave the way for the MMU/TF-X. TUSAŞ currently is aiming to complete the subsystem procurement of HÜRJET. When the subsystem, the engine, etc., is completed, it means most of the work is almost done, then the production stage will start. In early September 2020 TUSAŞ announced that they had established the HÜRJET Test and Evaluation Simulator dubbed HÜRJET 270. Equipped with artificial intelligence (AI) infrastructure, the HÜRJET 270 (with 270-degree field of view) engineering simulator is designed to collect feedback from test pilots to make the design of HÜRJET “better, more solid and more efficient.” The simulator is also meant to detect design faults at the development stage. Comprising less costly parts of the original aircraft while still containing its latest technological developments, the simulator will also be able to instantly detect errors encountered by pilots during test runs, a first for the defense industry. Thanks to its real-time software, size, and features, along with its wide viewing angle, existing risks will be identified and eliminated during the development phase. According to TUSAŞ the HÜRJET 270 simulator will feature “human eye-level resolution.” It will also collect data for future training simulators. The integration of the simulator’s avionic and flight control software, screens, cockpit components and communication equipment were completed by the TUSAŞ Prototyping Office. Speaking on the expected contributions from the HÜRJET 270 engineering simulator to the project, TUSAŞ Deputy General Manager Atilla DOĞAN said: “We have to develop the flight control algorithm and software and the avionics software before the plane is produced and assembled. The 270-degree engineering simulator we developed for HÜRJET provides us with a greater capability to make flight control algorithms, software and avionics software with the input of test pilots.”
On September 16, 2020 Stirling Dynamics of the UK announced that they secured a new contract from TUSAŞ to provide technical assistance in the areas of loads and aeroelastics for the HÜRJET aircraft program. This contract builds on previous support provided by Stirling Dynamics, which was initial consultancy to support TUSAŞ up to the HÜRJET’s Preliminary Design Review (PDR). Under the new contract, Stirling Dynamics will support TUSAŞ’ engineering team as they work towards Critical Design Review (CDR). Stirling Dynamics’ engineers will provide support in several formats involving training and guidance, expert review, and off-site work packages. Technical areas of interest include flight and gust loads, buffet, flutter, and validation testing. Henry HACKFORD, Stirling’s Aerospace Technical Services Business Unit Manager, commented: “We are delighted to have the opportunity to work with TUSAŞ again on their indigenous aircraft development program. The HÜRJET contract is the realization of a long-standing dialogue with TUSAŞ and provides an exceptional opportunity for us to demonstrate our key strengths.”

Is there any program started by Turkey to make turbofan of F404 class first (for hurjet + future hurjet ecosystem) before say attempting a class of F110 for TF-X (and its future eco system)?

There is no known program about Hurjet engine. However there is a program being started by TR Motor company for a turbofan engine for TFX. TR Motor is a design bureau company. They do not have production capability. They have been working on the design of a F110GE132 look alike engine. Specifics have not been released but there is a computer generated picture of the engine. And it features a Variable Inlet Guide Vane and as in the case with the F110-GE-132 engine it features “blisks” (bladed-disks) in the three-stage modular fan section in lieu of traditional blades to improve performance and maintainability.

Mr Mahmut Aksit has recently mentioned that they will be producing under license the F110-GE-129 engines for the TFX prototypes. As F110 engine was developed from f404 engine, there could be a point where the Hurjet’s f404 engines may be produced in the same manner.
Yeah because from what I understand, the F404 is to power the initial batches of Hurjet, but they leave it open after that...I guess depending on how the local engine development (f110 derivative) goes at large.
This is important especially for further ecosystem of this category (hurjet class) of fighter....as one would assume it has higher squadron requirement in TurAF long term compared to heavier types and air superiority like TF-X....not to mention assured export freedom etc.
Do you know what is the projected total number/squadron requirement of hurjet and TF-X as it stands right now (for TurAF) btw?

There are, at the moment , 68 operational t38’s as far as I know. (Give or take a couple) . So we need at least around 70 Hurjet’s to replace these. Then there is light attack aircraft quantities that are needed. As Turkish squadrons consist of 20 aircrafts , and let us say at least 3 or 4 squadrons will need to be incorporated; Then we are looking at another 80 planes. On top of that there will be export quantities if we can produce an engine in house with no strings attached, like the T700 Blackhawk engine or a totally indigenous one. So a program of 150 to 200 Hurjets wouldn’t be too outrageous.
Tfx is going to replace both 40 f4’s and gradually the f16’s. So around 280-300 aircrafts will be needed in the next couple of decades after 2028.
