I am Turkish and what you heard here may be wrong. If you have problems you can ask
Thanks, since this is indeed a most interesting type but my problem is that most Turkish guys in any forum I met are almost instinctly aggressive if you only question their claims. Therefore I would be very happy for any decent explanation and since I'm quite busy at the moment, here a summary I posted in another forum:
Again, the main problem with this project is simply IMO that no-one wants to wish Turkey bad luck or anything bad, but that most international, reasonable and well respected analysts all have too many open questions and that so far too few of them are answered.
In return any such critical question, remark or doubt is always alone rated an insult and replied in a most aggressive way.
IMO a forum is exactly the place to exchange opinions, even contradicting ones, to ask open questions and to get answers and explanations. If one expects only expects "whao huu ... the best fighter yet to come!" and nothing more, shall leave a discussion.
Son in summary if you look at this program as an outsider we have two side, both as different as they can be:
On the one side - the official one: The TFX/MMU is is a most impressive fighter, a great design and on paper the fighter looks very promising.
On the other side several international analysts and me too have several grave concerns in regard to the overall timeline, budget and especially its engines. This is based on the one side on the "unique social and political situation" in Turkey, which I rate unsecured and even more based on the fact that besides what Turkish sources claim the officially agreed use of F110 engines were so far not announced by either the USA or GE.
This is in strict contrast to any other foreign use of GE engines, be that in India, South Korea and so on and given the latest - to put it mildly - political dispute between the USA and Turkey and the lack of any official US confirmation I am doubtful.
As such my biggest concern are the engines. At least by my understanding (and here I'm open for corrections) it is a fact, that even if a country assembles or manufactures a US engine it cannot simply use it in another product without permission. At least by my understanding, the USA are very strict on this.
So in summary: I would be very much more optimistic if anyone could share not a YouTube-video claiming "it is so" but a credible source telling something about the terms of conditions for GE F110 that Turkey signed. Any bashing down of questions is neither constructive nor helpful.
Even more such nationalistic, stupid claims like "we could even copy it and GE won't even care!" or "if they don't agree, we will go the Russian way!" is not a proof for the agreement to use a TEI built F110. Only the US government - not even GE and surely never TEI - decides on the use of US high end engines. Why alone noting this fact is rated an insult by some is beyond my understanding.
Again, such an agreement is maybe done, but why then does no US source and most of all GE mention this, which is most unusual since GE usually mentioned any use of their engines by a foreign partner?
As such: without any authorisation from the US government, there is NO F110 available for the TFX unless Turkey ignores the US intellectual properties which in return even worse consequences.
Therefore in short: My wish for any discussion on this type would be an honest, open minded and civilised discussion, but without these points of concerns solved (and these are not my concerns alone) all such claims the TFX prototype 01 will be being ready in 2022 and will fly in 2023 is far from assured regardless what some constantly claim.
