CHARLOTTE, N.C. (AP/WCNC) - 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.

Former Central Intelligence Agency Director John Brennan spent Thursday afternoon at UNCC discussing national security. He said Putin’s speech underscores the importance of improving relations with Russia.

“We need to make sure we don’t allow Vladimir Putin to intimidate others, including ourselves,” Brennan said.
