"Russian strategic missile troops reportedly launched an RS-18 ballistic missile on Tuesday. The launch may have been a test of the advanced hypersonic glider warhead, which would be able to defeat US anti-missile systems.
The test was conducted at midday from a site near the town of Yasny, Orenburg region, in the southern Urals, and reached the Kura test range in Kamchatka in Russia’s Far East.
“The test was a success. The warhead was delivered to Kura field,” the Defense Ministry reported."
