KAAN is a success except engines and proven stealth. Anyone denying this is either blind or a liar.
You said something very specific. You claimed that-
KAAN's avionics and actual plane part is done successfully thanks to aeronautical engineer Temel Kotil.
To which @Sanchez replied, 'they most certainly are not.'
Either you engage with the argument or you don't. Indirect name calling is not okay.
KAAN's main sensor MURAD-600A hasn't been fabricated yet. It is still in the critical design phase. Without the actual physical thing, how is it done? And we are not even talking about the extensive testing and validation process yet. This is just one example.
