"The value of the deal with Turkey for the S-400 has exceeded USD2 billion," he said not providing any additional details.

Previously, the Presidential Aide for Military-Technical Cooperation Vladimir Kozhin said in an interview with TASS that Russia and Turkey had signed the contract for the S-400, and the preparation for its implementation had started. Later, he added that Ankara had already paid a deposit for the systems. At the same time, the Undersecretary of Turkey's Savunma Sanayii Mustesarligi (SSM, the Undersecretariat for Defense Industries) Ismail Demir said that the deliveries of the S-400 systems would start within two years.

In May 2017, it was announced that Turkey and Russia have reached principal agreements on the issue of the S-400 air defense missile systems acquisition.

The negotiations between Turkey and Russia over the acquisition of S-400 became known in November 2016. In March, the head of the Rostec state corporation Sergei Chemezov said that Turkey had revealed its willingness to receive a credit from Russia for arms acquisition including S-400. In February, Chemezov said that Turkey showed its interest in S-400 and the sides were conducting negotiations over potential deliveries.

In July 2014, China has decided to purchase the S-400 and was the first foreign customer of the Russian missile system. India is the second country after China, which ordered six S-400 battalions in 2014, to receive one of Russia’s most advanced air defense systems. China is expected to receive the first S-400 units in 2018.

The S-400 is a Russian-made air defense missile system, capable of carrying four different types of missiles able to destroy aerial targets at short, medium, long and very-long ranges between 40 and 400 km.
