In his state-of-the-nation speech Thursday, Putin said the nuclear-powered cruise missile tested last fall has an unlimited range and high speed and is capable of penetrating any missile defence.

He said the high-speed underwater drone capable of carrying a nuclear warhead could target both aircraft carriers and coastal facilities.

Putin said Russia also tested a new heavy intercontinental ballistic missile, called Sarmat, with a range and number of warheads exceeding its predecessor.
