"S-400 [systems] are already ours. We are continuing to learn to work with them. The air defence missile systems will be ready to be used in April. Yesterday, I told [Russian colleagues], that if the United States supplies us with Patriot air defence systems, we will buy them too", Erdogan said, as quoted by the Hurriyet newspaper.
The statement comes after US Ambassador to NATO Kay Bailey Hutchison stated that the United States hopes Turkey will give up Russia's S-400 air defence missile systems due to the development of the situation in Syria.
The US has repeatedly objected to Turkey's S-400 purchase, saying that the weapon system is incompatible with NATO security standards and might compromise operations of the new F-35 fighter jets.
