quote [ A leaked copy of the Pentagon’s Nuclear Posture Review states that Russia is developing a “new intercontinental, nuclear-armed undersea autonomous torpedo.”

But what really makes Kanyon nightmare fuel is the drone torpedo's payload: a 100-megaton thermonuclear weapon.

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. ]
