Serial production of the newest S-500 Prometheus air defense system could begin as early as 2020. This was stated by the head of Rostec Corporation Sergey Chemezov in an interview with RBC on September 16. At the same time, he stressed that the issue of any deliveries of the system abroad has not yet been raised and in the next 5 years it is likely not to be raised. According to Chemezov, this is due to two reasons. The first is the need to provide the Russian Armed Forces with a new anti-aircraft missile system. And the second: the huge demand on the international market of the older System S-400, which, as noted by the businessman, is well-sold. In addition, Chemezov also noted that individual components of the S-400 will be produced under license in Turkey in the coming years, as well as possibly in India and China. At the same time, the head of Rostec refused to answer the question of whether Beijing would become the first foreign buyer of the S-500 air defense system (as previously reported by the media).
