Yep, the narrative was Turkey can't even develop a 4th Gen fighter, that this was "domestic propaganda" they called it an "Iranian Hoax"/"North Korea Hoax" to fool their people, now suddenly they pivot to engine engine engine. Not only do they not acknowledge that Turkey flew a prototype, but AHEAD of schedule.
The engine is obviously definitely harder, but The project is already successful with GE110 engines. People forget that the Rafale flew with GE404 engine initially, and that the Saab Gripen flew with GE404 engine, yet no one uses the engine talking point against them.
These narratives are so annoying, Altay tank is a "failure" but K2 Black Panther is a success. when really they both have the same achilles heel of a German Powerpack. They try to compare it to the Arjun Tank, that actually has performance failures, not political failures. It not like the Altay didn't go into production b/c of other issues, they talk performed incredibly well in testing, the production hit a snag b/c of an embargo of engines, If the Germans did the same thing to the K2, would that be a failure?
