"There are many [states] that want our air defense complexes. First of all, Turkey has an option," the official said.
In December 2017, Russia and Turkey signed a loan agreement to supply S-400s to Ankara. According to a statement by the Turkish defense industry secretariat, two S-400 batteries will be operated and serviced by the Turkish military.
The S-400 Triumf system is a next-generation mobile air defense system, which is capable of destroying aerial targets at an extremely long range of up to 400 kilometers (almost 250 miles).
