  In late 2017 Turkish and Russian officials signed a US$2.5 billion agreement for delivery of the S-400 air defense system to Turkey. The US Secretary of State raised concerns over the deal, which were rebuffed by President Erdogan and other Turkish officials, citing the US refusal to sell the upgraded MIM-104 Patriot to Turkey, considered to be an important American ally by the US. Turkey received its first installment of the Russian S-400 missile defense system on 12 July 2019. On 17 July 2019, Turkey was suspended from the F-35 program, the US stating "F-35 cannot coexist with a Russian intelligence collection platform that will be used to learn about its advanced capabilities" and on 14 December 2020, the US imposed CAATSA sanctions on Turkey. As of 2020, 4 batteries consisting of 36 fire units and 192 or more missiles were delivered to Turkey.
