On Sunday, the Yeni Safak media outlet reported Turkey may purchase Su-57 jets if the United States blocks deliveries of F-35 planes because of Ankara's decision to buy Russian S-400 air defense systems.
"The reports are based on experts' opinions. We cannot confirm that. Such publications do not reflect the official government's position yet," the source said.
In mid-April, Assistant Secretary of State for European and Eurasian Affairs Wess Mitchell said Ankara's purchase of the S-400 air defense missile systems from Russia could negatively affect the delivery of the fifth-generation F-35 fighter jets to Turkey. In addition, a group of senators comprising both Republicans and Democrats wants to block the supply of F-35s to Ankara due to the arrest of US Pastor Andrew Brunson, who is being tried on charges of aiding terrorist groups.
