Russia has declassified the first ever image of its new thermonuclear-armed intercontinental ballistic missile, the RS-28 Sarmat.

In May this year Sputnik, a Russian publication aligned with the Kremlin, claimed the missile could carry a payload capable of wiping a landmass "the size of Texas or France".

Known colloquially as "Satan 2" the missile will replace its predecessor, the RS-36M, dubbed "Satan" by NATO after entering service in the 1970s.
