I have my doubts too, but..
As a reminder, the Yildirim missile, shown on a parade at the first time, was in our inventory 7 years before.
I dont know. Maybe I will call R.T. Erdo tomorrow and ask him for clarification.
Just speculation, I remember a speech of ???.. who said, the range of missiles are no more problems for us. In this context, Yildirimhan could be real.
