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. 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.
