Turkey’s acquisition date for S-400s is a purely technical issue, Ismail Safi, a member of the Turkish Presidency's Council of Security and Foreign Policies told RIA Novosti.
According to him, it’s not happen too late.
Russia completed this year a deal for the supply of four S-400 divisions to Turkey with $ 2.5 billion. The deal also includes an option for another regiment kit.
Deliveries of the latest Russian S-400 air defense systems, which caused a crisis in relations between Turkey and the US, began in mid-July. According to Erdogan, the S-400 will be fully operational in April 2020. Washington demanded a refusal of the deal, threatening to delay or even cancel the sale of the latest F-35 fighters to Turkey, as well as impose sanctions in accordance with CAATSA. Ankara refused to make concessions.
