Iran Press/Asia: Turkey's President Recep Tayyip Erdogan said on Wednesday he hopes a Russian missile system will be delivered in July.
NATO member Turkey also has signed up to buying 100, F-35s and has invested heavily in the F-35 program, BBC reported.
Turkish companies produce 937 of the plane's parts.
Turkey's plan to buy the Russian air defense system has been a cause of tension within the NATO military alliace, which both the United States and Turkey belong to.
The US had said Turkey could not have both the S-400 anti-aircraft defense system and US F-35 fighter jets.
But Erdogan said Turkey would hold to account anyone who excluded Turkey from the F-35 program.
Turkey has been pursuing an increasingly independent defense policy and has been establishing closer links with Russia after a recent souring of its ties with the US and Europe. 213/207
