More like so Erdogan has something to masturbate about.
Speaking of the dude, he and Putin have struck a deal that will see more S-400's delivered to Turkey. Four systems worth 2.5B USD will be delivered bringing Turkey's arsenals up to eight systems in total. Apparently, one system consists of eight launchers. (

Most of their tech is still of German or American made and obviously subject to NATO standardisation. Integrating the S-400 into their air defences must be a real bitch. The S-400 seems to be an immensely capable platform alright, but I'd really like to know if Erdogan's generals share his enthusiasm.
