Russia test-launched a new nuclear-capable intercontinental ballistic missile on Wednesday, Russia's defence ministry said.
The Sarmat missile had been test-launched for the first time from Plesetsk in northwest Russia and hit targets in the Kamchatka peninsula, nearly 6,000 km away.
The Sarmat was fired from a silo launcher at 1512 Moscow time (12:12 GMT).
Russia's nuclear forces will start taking delivery of the new missile "in the autumn of this year" once testing is complete, TASS cited head of the Roscosmos space agency Dmitry Rogozin as saying.
