Russian Deputy Prime Minister Yuri Borisov announced that the next-generation missile system, the S-500 Prometey (Prometheus), has entered the acceptance test phase. Borisov added that they are continuing to purchase parts for mass production of the system.

Russian Defence Minister Sergey Shoigu said the delivery of the S-500 missile system to troops would begin in 2020.

The Military Aviation Academy in Tver has been training experts to use the new system since 2017.

The S-500, which is said to destroy hypersonic weapons along with aerodynamics and ballistic targets, is expected to neutralize targets from a distance of 600 km.
