Turkey may adjust technical parameters of the S-400 air defence systems bought from Russia if the United States proves alleged risks that the complexes pose to the US military facilities, Turkish Defence Minister Hulusi Akar said on Tuesday, ONA reports citing Anadolu Agency.
"S-400 will most likely be set to protect Turkey's strategic cities and facilities near Istanbul and Ankara. At the same time, the F-35 aircraft will be stationed at the air base in Malatya. These cities are located far from each other. If the US side proves the existence of a threat, we will make changes to the parameters of the S-400 systems," the minister said.
