Russia has tested the nuclear-armed Sarmat missile Satan-2

According to the country's president, Vladimir Putin, the missile - said to be capable of carrying several nuclear warheads simultaneously - has a range of over 35,000 kilometers.

It is to replace its predecessor, the R-36M, which had less than half the range and was given the NATO reporting name "Satan".

The Sarmat was first announced in 2018. Now Putin claims that the missile could begin to be deployed and reach combat readiness by the end of the year.
