The missile, which was first test-fired in December 2017, was launched from the Plesetsk spaceport in northern Russian Federation.
Dubbed a "powerful and modern" system by Russian President Vladimir Putin earlier this month, the Sarmat system is meant to have a worldwide rage, and to be able to bypass any current missile defense system. The Russian Defense Ministry posted video footage of the launch.
The U.S. joined the United Kingdom and several European Union nations in punishing Russian Federation after a former double agent and his daughter were attacked with a nerve agent on the streets of Salisbury in the United Kingdom.
The first launch of this rocket took place in late December past year. The U.S. and other countries have expelled some Russian diplomats.
Putin has made much of developing such "invincible" systems as a counter to costly U.S. missile defense programs.
The supersonic RS-28 Sarmat is believed to be capable of carrying up to 10 or 15 nuclear warheads.
The secretary general of the United Nations, António Guterres, said the crisis recalled the Cold War, The New York Times reported, only without the controls and channels of communication established before the 1991 collapse of the Soviet Union "to make sure things would not get out of control when tensions rise".
"It's a response to USA abandoning anti-missile defense treaty and building up its potential".
He said the Sarmat missile is "a new weapon in response to the deployment of missile defense by the US overseas".
"It can attack any target, through the North or South Pole, it is a powerful weapon and no missile defence system will be able to withstand", he said.
