In May 2018, Turkish media Yeni Safak stated that Turkey might evaluate Su-57 purchase if the US cancels F-35 deliveries due to Turkey's S-400 purchase. However, internal source stated that the possibility of Su-57 purchase was based on expert's opinion and do not reflect the official position of Ankara. While on 30 June 2018, Turkey received its first F-35 in a ceremony at Lockheed Martin's facilities in Texas, the US ultimately expelled Turkey from the F-35 fighter programme after the first S-400 delivery in July 2019.
