Turkish President Tayyip Erdogan has said that the purchase of S-400 defense systems from Russia is a done deal and Ankara would also jointly produce S-500 defense systems with Moscow.
In a televised question and answer session with university students in Istanbul he said the U.S. officials have called Turkey’s planned purchase of S-400 missile defense system deeply problematic.
He said it would risk Ankara’s partnership in the joint strike fighter F-35 program because it would compromise the jets, made by Lockheed Martin Corp.
