Turkish Air Force's fleet includes over 200 F-16 fighters, Defence Blog, March 13, 2015.
In fact, Turkey was initially a production partner in the F-16 project at the very beginning, circa late 1970s.
And also little known is that they and the Israelis have cooperated very closely on remanufacturing and maintaining a big fleet of F-4s.
Of course, that was just before Erdogan.
And crazy enough, Turkey built this immense air fleet to threaten another NATO member, Greece.
