Kanyon is reportedly a very long range autonomous underwater vehicle that has a range 6,200 miles, a maximum depth of 3,280 feet, and a speed of 100 knots according to claims in leaked Russian documents.
But what really makes Kanyon nightmare fuel is the drone torpedo’s payload: a 100-megaton thermonuclear weapon. By way of comparison, the atomic bomb dropped on Hiroshima was 16 kilotons, or the equivalent of 16,000 tons of TNT. Kanyon’s nuke would be the equivalent of 100,000,000 tons of TNT. That’s twice as powerful as Tsar Bomba, the most powerful thermonuclear weapon ever tested. Dropped on New York City, a 100-megaton bomb would kill 8 million people outright and injure 6 million more.
Kanyon is designed to attack coastal areas, destroying cities, naval bases, and ports. The mega-bomb would also generate an artificial tsunami that would surge inland, spreading radioactive contamination with the advancing water. To make matters worse there are reports the warhead is “salted” with the radioactive isotope Cobalt-60. Contaminated areas would be off-limits to humanity for up to 100 years.
And being sea-based makes it immune to ballistic missile defense.
