Russia Building Underwater Nuclear Drone

An internal Pentagon nuclear study confirms Russia is developing an intercontinental-range nuclear-armed underwater drone.

The autonomous torpedo is among an array of new strategic weapons being developed by Moscow as part of a nuclear modernization underway over the past decade.

Russian nuclear modernization includes multiple upgrades for older missiles, launchers, bombers, and submarines, according to an internal draft of the Nuclear Posture Review, a major policy study to be made public in final form later this month.
