(14.6.2018) “Besides [the S-400s], I have made a proposal to Russia for the joint production of the S-500s,” Erdoğan said in a televised interview late June 13.

The S-500s are still under development and believed to be deployed by 2020 as a supplement but with a longer range to the existing S-400s sophisticated surface-to-air missiles. Turkey will procure the S-400s to augment its air defense by July 2019.

In reaction to some countries’ opposition against the Turkish purchasing of S-400s, Erdoğan recalled that Greece has an earlier version of Russian air defense systems, the S-300s, on its soils.
