The United States has sent the world's largest underwater nuclear missile submarine, USS Rhode, to European waters, sending a stern message to Russia; here is all you need to know 

The USS Rhode Island also goes by the name “Horsemen of the Nuclear Apocalypse” as it can carry 150-200 nuclear warheads. 

The massive submarine can carry 24 Trident II ballistic missiles. The maximum range of these missiles is 18,000 km and their flight speed is 29,000 km/h.

Military experts believe sending the USS Rhode Island should influence Russia and force it to abandon possible plans for a nuclear strike on Ukraine. 

USS Rhode Island is supposed to head over to a strategic position in the Black sea in response to the Russian nuclear submarine Generalissimus Suvorov testing a ballistic missile

The Italian newspaper la Repubblica labeled the appearance of USS Rhode Island in the European region "a message to Putin".
