This was a stoppage of sending spare parts. When and by whom were the original F-35s sold? Glad to see them cracking down on Erdowan. Of course, he may now try to buy the F-35 equivalent from Russia, which we may also not like unless we prefer to make Putin happy.
The spare parts have to be in place before the aircraft are delivered. Turkey’s F-35s are currently in Texas and their pilots and support crews are training on them in anticipation of their transfer to Turkey.
Russia doesn't have an F-35 equivalent.
