And why this is a big deal now
From my point of view it's just misplaced skepticism. I would share the same feelings but it's exactly why we have hired SAAB's assistance to compensate for our lack of experience in this field. Nobody gives a phuck about what public thinks, don't be such a drama queen
End result is what matters and you and i both know Turkish Air Force won't spend a penny on an inferior platform.
I can say this with %90 certainty that TFX will fly with twin TEI built GE F110 engines. I also expect it to carry an AN/APG 81 AESA radar, AN/AAQ-37 F-35 Distributed Aperture System and the Integrated Helmet and Display Sight System (IHADSS). Aselsan will take of the rest of the avionics(glass cockpit, fly-by-wire and fire controls). They may even replace some of the American subsystems I've mentioned with indigenous solutions but right now I can say that the most complex parts have already been taken care of.
For now, the only challenge is the design and development of a new stealth airframe. TAI is already producing the mid section of the F35 airframe so I have full confidence in them to carry out this project. I also trust SAAB's capability to provide all the assistance we need since they have a great track record going back to J35 Draken.
