Turkey’s reception of the first batch of the S-400 strategic air defense systems from Russia last month was loaded with symbolism that offers clues on why Ankara made the controversial purchase and the threat perception that prompted the move. In reverse order of importance, they could be listed as follows:

First, the delivery began July 12, three days ahead of the third anniversary of the failed coup attempt of July 15, 2016, which was led by followers of US-based preacher Fethullah Gulen within the Turkish military. This could not have been a coincidence. The delivery had been rescheduled to start in July 2019 upon Ankara’s request, a decision that was announced in April 2018.

As the Turkish servicemen who will operate the S-400s are still receiving training in Russia and the systems are said to become operational in April 2020, there was hardly any military urgency to explain why the carrier components had to be delivered by air. That the missiles would be delivered later by sea was already known. So, the arrival of Russian planes carrying S-400 components on the eve of the putsch anniversary was a flag show signaling that Turkey’s place in the world has changed.

Another important sign was the live broadcast of the Russian planes landing at the Murted air base outside Ankara. Few countries would live broadcast the importation of weapons on their TV channels and online media. The rare spectacle was intended to make sure that the world sees this big moment, symbolizing the change in Turkey’s geopolitical posture and alliances.
