Russia Today:
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 the warhead 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.
Popular defense blog MilitaryRussia.ru says the launch was meant to test Russia’s hypersonic glider warhead, currently known by its developer designation, ‘object 4202’, or Aeroballistic Hypersonic Warhead.
