MOSCOW - (AP) -- President Vladimir Putin says Russia has tested new nuclear weapons, including a nuclear-powered cruise missile and a nuclear-powered underwater drone, that would be immune to enemy intercept.
Speaking in a state-of-the-nation speech Thursday, Putin said that the nuclear-powered cruise missile tested last fall has an unlimited range and high speed and is capable of penetrating any missile defense.
He said the high-speed underwater drone capable of carrying a nuclear warhead could target both aircraft carriers and coastal facilities.
Putin said that Russia also tested a new heavy intercontinental ballistic missile, called Sarmat, with a range and number of warheads exceeding its predecessor.
