As noted, the tests began on July 4 at the Myurt airbase near Ankara and will last until November 26.

It is indicated that the Turkish Air Force planes will fly at high and low altitudes.

As Defense News previously wrote, Senator John Thune proposed an amendment to the Senate that would allow the United States to buy back Russian S-400s from Turkey. 

The FSVTS, commenting on these reports, emphasized that the transfer of the S-400 to another state without Russia's permission is impossible. 

On May 8, they announced in Turkey that they had partially commissioned the Russian S-400.
