Russian footage shows ballistic missile launch
STORY: The test of the Sarmat, under development for years, did not surprise the West, but came at a moment of extreme geopolitical tension. Russia has yet to capture any major cities since it sent tens of thousands of troops into Ukraine on Feb. 24.
Ukraine's defense ministry was not immediately available for comment.
Announcing what Russia calls a special military operation eight weeks ago, Putin made a pointed reference to Russia's nuclear forces and warned the West that any attempt to get in its way "will lead you to such consequences that you have never encountered in your history."
Days later, he ordered Russia's nuclear forces to be put on high alert.
Russia's defense ministry said on Wednesday the Sarmat was fired from a silo launcher at 1512 Moscow time (1212 GMT).
