Leaked Pentagon documents provide detail on "Kanyon," a Russian undersea autonomous torpedo
that is being described as "nightmare fuel": the payload is a 100-megaton thermonuclear weapon, equivalent to 100,000,000 tons of TNT. It is supposedly capable of penetrating ballistic missile defenses.

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.
