Just for the record a short notice from Russia...
"Supreme Commander-in-Chief of the Russian Federation Armed Forces Vladimir Putin received a report via videoconference from Commander of the Strategic Missile Forces Sergei Karakayev on the successful test of the Sarmat missile.
...
First, it is the most powerful missile system in the world, comparable in strength to the Voyevoda missile system previously in service, which, as mentioned earlier, was developed during the Soviet era. The combined yield of the payload is more than four times greater than that of any existing Western counterpart
...
Secondly, and most importantly, the missile is capable of travelling not only along a ballistic trajectory, but also along a suborbital one. This, and this is the third point, extends its operational range to over 35,000 kilometres while simultaneously doubling the accuracy. Finally, it makes the missile capable of penetrating any missile defence systems that are in service or in development at this time. The Sarmat will indeed be placed on combat duty by the end of this year."
