If the F110 engines cannot be procured, I believe we will have to resort to a rather
risky course of action. That risky course is this: Delivering the Block 10 Kaans using immature TF35000 engines, which offer F110 thrust values. This would save the Kaan program from a complete collapse.
Even then, by my estimate, the Kaan program would be delayed by approximately two years. The first Kaans would be delivered in 2030, not 2028, at the best.

However, if the F404 engines cannot be procured, the Hürjet program would certainly collapse. Because, a) There is no money or manpower to redesign the aircraft, as Temel Kotil has said; and b) Developing a new engine would take 10 years, at the best!

I believe the USA will not finalize the F404 procurement until the fate of the Boeing T7 is clear. If T7 fails, i believe USA will deliver the F404s. Because in that case, the USA will also need Hürjet. I cannot predict what the USA will do regarding the F110. If the T7 doesn't fail, will the US deliver the F404s? Just like with the F110s, I can't predict that.
