In a written statement, the Turkish Defense Ministry said that the first batch of S-400s was delivered to Murted air base, formerly known as Akinci air base, located in the northeastern suburbs of Ankara.
According to the South Front, Turkish Defense Minister Hulusi Akar confirmed that the S-400 batch had been transferred to the Murted air base near Ankara. Turkish media also released a video showing a Russian plane there.
The transfer of the S-400 missile system will continue in the coming days, according to the Turkish Defense Ministry.
Russian news agency TASS quoted some military diplomatic sources as saying that another Russian plane is expected to carry a second batch of S-400 missiles to Turkey in the near future.
The source added that the third shipment, carrying "220 anti-aircraft missiles of various types" will be delivered "expected to be by the end of the summer, by sea".
TASS also quoted a source as saying that Turkish S-400 operators will travel to Russia for training in July and August. About 20 Turkish soldiers were trained at a Russian training center in May and June.
Turkey's cooperation with Russia in this missile system has been strongly criticized by the NATO and US alliances. In April, the Pentagon said Turkey's use of Russian-made missiles could pose a security risk to F-35 fighters and NATO defense systems, and threatened to stop selling the F-35 unless Turkey canceled the S-400 contract.
However, Turkey has not given up under pressure from the US, emphasizing that buying any weapons is a matter of national sovereignty and does not target any third country.
Turkey and Moscow signed a $2.5 billion deal to buy two S-400 complexes, Russia's most advanced long-range anti-aircraft missile system.
Turkey is the first NATO member to purchase the equipment.
