I wish we were able to produce some of the parts Spain wants cheaper, this they'd pick ours. But I think it's just as much an investment into keeping the know how and capabilities alive in Spain.

EDHs were assembled in Ankara, not Italy.

Per the deal we saw, Hürjet production will be again be in Ankara, not Spain.
That's correct, but the first 45 are empty. They are being equipped in Spain with purely Spanish components. We do the donkey work, the Spaniards do the fine work.

I want to explicitly assure you, Spain has something bigger planned with SAETA. They recently secured 250 F404 rotors, and with immediate delivery at that.

I had expected HÜRJET to be a sales hit, but I did not anticipate the name SAETA. The Spaniard has pulled off a great coup. SAETA will be a sales hit. We will see what we could get in return for such a poorly looking deal. To be honest, I have no hope in that either.

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, 2025The 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.
