TAI HURJET

"According to the article published in MDPI on June 1, 2025, Hürjet will be equipped with an artificial intelligence-supported terrain-referenced navigation system. The system will provide precise navigation, especially in environments where GPS access is unavailable.

The Ministry of Defense will invest 1.375 billion euros in the Air Force's new advanced trainer and expects the first aircraft in 2028.

It is insisted that this is a joint development with Turkey's TAI, based on the Hürjet but with national design authority.

For the first prototype asa a fail safe, though. TAI has also developed another fly-by-wire for the Hürjet, that is flying rigorously.

You have to have in mind that it was the first fly by wire that TAI had developed back then and they needed a fast solution to get the prototypes in the air ASAP. With this experience, they've designed the fly-by-wire of the Kaan and the flying wing Anka-3.

This is old news (from around 2020-21), really...

Thanks for the elaborate reply.

Do you have any articles on this which I can read? Or any pdf or slides showing Leonardo's involvement.

I meant any literature which I can refer to.

We pretty much share every newsworthy thing here, so you should go back a dozen pages or so and start from there.

I distinctly remember either me or @Combat-Master sharing the Hürjet Project Manager's interview about the FBW during the rollout ceremony of Kaan.
 
We have signed a significant memorandum of understanding with GE Aerospace for the F404 turbofan engines (the heart of our country’s first jet trainer aircraft, HÜRJET).

This agreement will be an important step toward reaching new customers in the HÜRJET program.

We look to the future with confidence and continue to rise by strengthening our national aviation technologies through international partnerships.

TUSAŞ and Airbus have signed a cooperation agreement for HÜRJET;

Under the partnership, the export details of the HÜRJET Jet Trainer have been further clarified. It has been agreed that up to 30 HÜRJET aircraft will be procured to meet Spain’s jet trainer requirements. The final sales agreement is expected to be signed by the end of 2025, with deliveries planned to begin in 2028.

I feel that it's going to be a logistical nightmare that half the fleet will be delivered in its original configuration with Turkish avionics and systems and the other half will be a hybrid with Spanish components installed. But I guess they are desperate to retire their current fleet of trainers.

Interview with TAI CEO.

Signing of final agreement for export to Spain is expected in end of September or in October.
30+ Hürjets will be exported.
There will be three phases.
First phase is that TAI will build like 15-20 Hürjets without any changes to avionics (turkish avionics).
Second phase will be that the rest will be build with spanish avionics (i think he means too that the planes will be build in spain).
Last phase is that the previously build Hürjets, from the first phase, will get spanish avionics too.

A production line for Hurjet in Spain is not feasible with the numbers of aircraft Spain is planning to buy, says Demiroglu. With the need to begin deliveries in 2028, a first batch of six aircraft will be delivered in a similar configuration as those destined for the Turkish Air Force. That is the “fastest way to advance their (Spanish Air Force) needs,” he says.

A second batch of aircraft will be delivered later once the modifications and adaptations with the Spanish subsystems are certified and ready; this will be done by Airbus in Spain. Eventually, all of the aircraft will be converted with the Spanish subsystems, with the modifications requiring a supplemental type certificate. According to Demiroglu, the new agreement makes it 95% clear who will do what.

“The remaining 5% is where the final negotiations are underway, including on certification … There are different approaches, but there are no showstoppers. We want to make sure the timeline of the project doesn’t get affected negatively and the cost of the project doesn’t increase unnecessarily,” he said, adding, “Each step tells us we are moving forward.”

The current Spanish government is fouling up, right, left, and center, as the saying goes.

Fun fact: the spanish mechanics will be quite knowledgeable about the Hurjet turbofan... same F404 engine as the Hornets presently flown by the Ejercito del Aire. I've just realized this little factoid.

It's not exactly the same. The Hornets fly with either -400 or -402 versions. The Spanish Hornets have the -400 model. This is different to the -104 model in the Hurjet. It might sound like semantics but the differences do affect ability to support fully.
 
Spain's ITS-C program

Program Overview
  • Purpose: The ITS-C program seeks to replace the Spanish Air and Space Force's (Ejército del Aire y del Espacio, or EA) aging F-5M (AE.9) advanced training aircraft fleet with a modern Integrated Training System-Combat (ITS-C). This system is based on the Hürjet platform, adapted to Spanish requirements through collaboration with national and international defense industries.
  • Adaptation and Configuration: The Hürjet will be customized with a "Spanish configuration" developed by Spain's aeronautical and defense sector. This includes integration of higher-performance systems (e.g., advanced avionics and armaments) produced domestically.
Procurement and Production Details
  • Quantity: Up to 45 aircraft.
  • Production Process:
    • Initial manufacturing at Turkish Aerospace (TA) facilities.
    • Subsequent conversion and equipping at Airbus Defence and Space, SAU (Airbus DS España) facilities in Spain.
  • Consortium Structure: A Unión Temporal de Empresas (UTE, or temporary joint venture) will handle development and execution, comprising TA and Spanish firms, with Airbus DS España as the lead national coordinator.
  • Financing: Advance prefinancing of €1,040 million allocated to Airbus DS España, which will pass it to the UTE. This follows models from prior programs like Tigre MKIII (Royal Decree 1009/2022) and Halcón (Royal Decree 891/2023).
  • Timeline:
    • Deliveries begin in 2028.
    • First aircraft operational for training in the 2029/2030 academic year.
    • Full deployment at Base Aérea de Talavera la Real (Badajoz).
  • Operational Life: At least 30 years.

TEI Chairman Fahrettin Öztürk announced:

HÜRJET engine approval officially received
In his statement on the matter, Fahrettin Öztürk stated, "We had submitted engine permit requests to the US Congress for both the HÜRJET and the KAAN. We have received our engine permit for the HÜRJET, and it has been completed. As you know, that is the F404 engine," confirming that a significant obstacle has been overcome for the mass production phase of the project.

This development eliminates the uncertainty surrounding the integration and mass production of General Electric's F404 turbofan engines onto the HÜRJET platform.

Process continues for the KAAN project
It was emphasized that the process for the KAAN, a fifth-generation fighter jet project intended to be Türkiye's most strategic asset in the skies, is being closely monitored.

Öztürk stated that the Congressional approval process for the engines to be used in the mass production models of KAAN, which performed its prototype flights with General Electric F110 engines, also used in F-16s, is ongoing, and emphasized that the outlook is not pessimistic.

The first bold sentence is very peculiar; according to official schedule, TuAF is supposed to induct the first jets in 2027, not 2026 (unless trainers are scheduled for 2027 while the demo jets are sch. for 2026?).
Series production activities continue within the HÜRJET Project. In this context, the process is progressing in line with the Turkish Stars’ delivery schedule planned for 2026.

While assembly activities for the aircraft to be delivered are ongoing, the first flights of the newly produced aircraft are planned to take place in the first quarter of next year.

it's certainly a bit tight, don't know if >300 sorties (~500 by then) is enough to qualify the jet for service entry...

With this initial order, Hürjet is soon set to replace the NF-5s of the Turkish Stars aerobatic team. Follow up orders of close to 80 or likely more aircraft are also expected, and the Naval Aviation branch is also seriously interested in a navalised version of Hurjet.
