“There is a possibility,” Borisov told Interfax, commenting on the possibility of Ankara buying Russian air defense systems.

In December 2019, Turkish Foreign Minister Mevlut Cavusoglu stated that Ankara acquired the S-400 after the refusal of the United States, France and other allies to sell their air defense systems.

In November 2019, Russia completed early deliveries of all S-400 components to Turkey.

In an interview with Nation News, military expert Boris Rozhin praised the statement by Assistant Chief of Staff of the British Air Force Julian Ball about the danger of the S-400.
