Russia's S-400 are the best missile defense systems in the world, Turkish President Recep Tayyip Erdogan said on Monday, TASS reports.
"S-400 deliveries to Turkey have begun. What has been said about this? It was said that we will be unable to purchase them and get them delivered. By April 2020, these systems will be fully deployed on the territory of our country. We hold true to our words as Turkish people. S-400 is the best missile defense system. I hope that we will produce it together with Russia," Erdogan said.
