A general rule of thumb within Turkish defence community is that never believe what anyone else besides officials say on live TV. Senile, retired generals making unbased claims on TV to make a buck are literally dime a dozen over here.as you said, TF-6000 first prototype assembled and they tested then dissemble and again assembling process start for further testing.
Under the project initiated by the Secretariat of Defense Industries (SSB) and carried out under the responsibility of TEI, Türkiye’s first military turbofan engine, TF6000, has been successfully tested. Designed to acquire technology and demonstrate capabilities on the path to the engine of Türkiye's first fighter aircraft, KAAN, the TF6000 was engineered to have the characteristics of an advanced military turbofan engine.
first prototype assembling started in late 2022

my point is, they are still on 6000 lbf thrust engine being second unit assembling. how on earth they already produced 39,000-40,000 lbf engine and integrated too with KAAN for testing fuselage dimension. before integrating with aircraft, such engine go through with long process of different set of ground testing then engine will integrate with aircraft for final stretch. i m sure you know it very well.
this is such a huge claim .. no doubt Turkey is working on it.
@Radonislav
Even then, I'm not dropping names but we had some officials in the past who'd try to dumb down their explanations to their crowd and this would cause frequent misunderstandings among us.

Aside from that, there have been rumors that a mockup of the TF35000 engine might be revealed to us in next year's IDEF fair. It's obviously nothing official though so don't hold your breath...
