TR HÜRJET-Advanced Jet Trainer/ Light attack aircraft

[Yasar_TR]

Let us get few basics out of the way first:

Every compressor stage consists of a stator and a rotor. Stator is stationary and it’s fans guide the airflow pushed in to them by the rotating “rotor” fans, to the next stage.

Should the Rotors that are in the f404 engines used in the Spanish FA/18 planes have had blisks, then they would be buying “rotors”. But the US document clearly states the purchase of “fans”.

The F404 engines made for India uses blisks to enhance performance. That means that fans come already friction welded on to the rotor. But the Spanish FA/18s (known as C15 series) use non blisk fans.

So as per the US FMS document states, the sale is for fans. Not rotors. US is stopping the use of these for their Hornets. These parts are important to keep the 80-83 planes in the air.(remember each plane has 2 engines and each engine has 3 LP fan stages plus 7 HP compressor stages). To be able to fit 160+ engines with fans quickly, is important.

So in short this purchase has nothing to do with Hurjet.

WASHINGTON, December 22, 2025 – The Department of State has made the determination to approve a possible Foreign Military Sale (FMS) to the Government of Spain of F-404 engine rotors and related equipment, at an estimated cost of $200 million. The Defense Security Cooperation Agency (DSCA) has delivered the required certification notifying Congress.

The Government of Spain has requested to purchase an additional two hundred (200) rotors of the F-404 engine, which will be added to a previously approved case whose value was below the threshold for notification to Congress. The original case was worth $98.8 million ($11.25 million in U.S. Defense Materiel – MDE), and included fifty (50) F-404 rotors, power systems, receivers/exciters (CP-1325/APG-65 and R-2089/APG-65), and associated services and equipment, spare parts, consumables, accessories, delivery of classified software, and support.

This new notification includes a combined total of two hundred and fifty (250) F-404 rotors. Other non-classified items are also included, such as: power supplies (CP-1325/APG-65), receivers/exciters (R-2089/APG-65), spare parts, consumables, repair services, logistics support, technical documentation, training, technical studies, contractor logistics support (CLS), U.S. Government and contractor technical support, as well as other logistics-related items. The total estimated cost is $200 million.

The proposed sale will support U.S. foreign policy and national security objectives, enhancing the security of a NATO ally that represents a key force for political and economic stability in Europe.

The operation will enhance Spain's ability to deal with current and future threats, and strengthen interoperability with U.S. and other allied forces. The enhanced capability will also bolster the defense of the homeland. Spain will have no difficulty incorporating this material into its armed forces.

The sale will not alter the basic military balance in the region.

The F-404 engine rotors will be transferred from U.S. Navy stock. Currently, no offset agreement is foreseen related to this sale. If any, it would be defined in the negotiations between buyer and contractor.

Although it is not a spectacular purchase in terms of public visibility, this operation is technically crucial. Spain secures access to a high-wear component for its fighter engines, guarantees the operational continuity of its current fleet and paves the way for the entry into service of the Hürjet without logistical risks.

It is undoubtedly great news that, although orphaned of great informative boasts, will allow the appreciated Hornets to fly. And in times of uncertainty, that counts.

In addition, this acquisition aligns with the recent decision to incorporate the Hürjet, an advanced trainer that also uses the F404 engine. Although these are not complete engines, access to these components will allow Spain to create an initial logistics stock to support the first Turkish aircraft when they arrive in national territory.

Kindly provide a source for this part you added in to the end of the DSCA notice or you might just get a warning for misleading forum users. This is manipulation 101.

What's the point of you doing this?
Literally spreading baseless conspiracy theories that apparently go only in your head. Stop it!

 

[Huelague]

EDHs were assembled in Ankara, not Italy.

Per the deal we saw, Hürjet production will be again be in Ankara, not Spain.

@Yasar_TR said "from Italy" not "in Italy".

 

[Ahlatshah]

It is official now

Excellent news.

Exporting 30 pieces of aircraft, to a NATO country, to Spain. Who would think?

May it be the first of many export success for Hürjet, may it be the same happen for KAAN

 

[Quasar]

HÜRJET has opened doors to new opportunities with its export to Spain:
Presidency of Defense Industry President Haluk Görgün:
• This agreement is not just an agreement for a training aircraft. Along with this training aircraft, it is a contract that includes many innovations in terms of both ground systems and simulation systems, as well as maintenance systems and a cooperation model, as a package
• I want to express that it is an opportunity for subsequent models to be developed together and exported to third countries in other versions
• While sharing ASELSAN's major agreement with Poland, I had stated that I would announce an even larger agreement within a week.
Here it was, this HÜRJET agreement

So this confirms P2 wasn't painted in Spanish colors to celebrate the sale and it was just editing.

 

[Quasar]

Limits for pilots in HÜRJET and KAAN are being removed:
• HAVELSAN, within the scope of the HÜRJET project, is achieving Turkey's first embedded simulation system integration into a flying platform
• Phase-1 Factory Acceptance Tests have been successfully completed under the HÜRJET Embedded Training System Project, which is positioned inside HÜRJET, removes limits in training, and will enable pilots to receive training during flight
• The first version software delivery of the embedded training system developed for the National Combat Aircraft KAAN has been carried out, and work has begun on the second version
• Embedded systems will also play a supportive role in efforts toward the 6th generation

[Zafer]

This is what I was talking about, Kaan can teach the pilot how to fly, there is no need for other planes. A pilot does not need to go through all the old school phases of flight training. Kaan will be safe for both the pilot and itself.

Big part of modern jet training is cost management. If you ever go to İzmir you'll see that tens of T-38s start their routine every monday at 9 and fly in business hours until Friday 5PM. That's hundreds of flighthours every month. It's expensive. Doing LIFT training with Kaan is just meaningless. It is literally the single most expensive aircraft design our air force could think of.

But, all these simulators and SIM modes will make conversion training when the pilot joins the squadron much easier.

You will be saving from keeping costs of lots of other planes. Pilots will not need to transition from one plane to another. Ground simulations will also be part of this. It is better to waste a couple more planes for training than partitioning the training between multiple platforms. It will take a shorter time for sure. Cost will still be be tolerable and Kaan will get more attention and be perfected as the only son of the family and one of our own making.

We don't need to be a follower in following traditions we need to be the innovator and a leader as it can be the new trend of the modern pilot training.

 

[Quasar]

Kaan traning is/will/should be fundumantly diffrent it is not only teaching the flight characteristics of KAAN but you are creating a sensor fusion commander in the cockpit for a variety of mission sets... There is no twin seat KAAN, F 35 or F 22 ......

For Kaan we can assume that the traning will be may be similar to F 35 or F 22;

-Academic Phase;

Stealth theory & signature management, Sensor fusion logic.......... Data links (MADL + Link-16 integration (Yes Data links are a part of the Academic Phase)...............

50–70% of training time is Simulator Phase..... rumor is that pilots find simulator harder than real flight.... since I guess they are trying all possible crazy scenarios in a safe enivornment ..... this is the essence of a simulator.

Actual fright traning is still near % 40

- Flight Training Phase ( conversion course) most of our pilots will be coming from F 16

-Tactical Phase

However, Simulator is not a substitution to the actual flight traning but it is there for preparing the pilot to the complexity of the plane and providing a safe and controled enivornment to implement complex scenarios

 

[Zafer]

We should keep a good number of pilots and we should train them fast

This flight is dedicated in respectful memory of those who lost their lives in the tragic train accident in the town of Adamuz, Spain. We share the grief of those who perished in the accident and extend our deepest condolences to the people of Spain.

Simple detail, both prototypes were in air. Wonder what's the latest sortie number for the program is. They were on flight 300 back on October 10.

 

[Samba]

When should we expect serial production start?

 

[Saithan]

I miss hearing more good news about Hürjet. Not about export, but about our own AF getting them.

Türkiye’s advanced jet trainer Hurjet to enter mass production

Prototype completes about 260 flight hours as Türkiye prepares to sign export deal with Spain - Anadolu Ajansı

www.aa.com.tr

If you check this news, TAI is establishing a production line capable of building two aircraft per month. TuAF to receive 16 units initially. Further quantities will be added as new configurations are added. Hurjet is scheduled for delivery to the Turkish Air Force’s aerobatic team, Turkish Stars, in 2026.
For this to happen, the engine manufacturing at TEI must be at an advanced stage, since all engines will be manufactured by TEI under license.

Spanish deliveries won’t start until 2028. So there will be quite a bit of a learning curve before Spanish Hurjets start rolling out of serial production line.
At 2 jets per month production rate and first deliveries starting in 2026 to TuAF (most likely towards the end of the year) , majority of the 16 jet initial order will be coming out of the production line in 2027. This coincides well with the given delivery dates for Spanish Hürjets.

 

[Nutuk]

I thought they were also preparing the TOMTAS facilities to assemble planes, plans have changed?
