Defending against Russia’s 100 megaton nuclear tsunami drone torpedos in Cold War 2.0

by

Russia has development of 100 megaton and megaton class tsunami generating nuclear drone weapons.

The weapon could explode in shallow waters off of a coastline and generate a tsunami hundreds of feet high. Such a tsunami could devastate all of Florida and the east coast of the United States.

On November 27, 2016, had a successful test launch of the drone submaroine from the Sarov submarine.

Characteristics expected of Russia’ drone weapon:

Diameter 1.6 meter
Length – 24 meters
Working depth – up to 1000 meters.
Drivers – water jet
Nuclear reactor – 8 MW, small-sized on liquid-metal coolant
Cruising speed – up to 55 km / h
The maximum speed is 100 – 185 km / h.
The range is up to 10 thousand km.
The warhead – with a cobalt section, for maximum radioactive contamination of a huge territory.
The power of the warhead is 100 Mt.
Low-visibility for hydroacoustics SOSSUS – up to 2 – 3 km at cruising speed of the vehicle

a one-hundred megaton weapon could be exceedingly heavy and thus “difficult to control.” Monterey nuclear weapons expert Jeffrey Lewis is quoted reassuringly as saying: “I think we could build defenses against it … It should be easier than intercepting an ICBM missile.

The US and other countries would need to have better and more comprehensive sonar underwater monitoring networks.

There would need to be interceptor submarines and drones to prevent this kind of weapons from reaching within 400 to 1000 miles of a coastline.

The flaws in terms of moving and controlling the nuclear drone submarine could be addressed if there were an arms race. The next versions could have more size and speed and stealth.

Maintaining command and control would be an issue. Russia would not want an opponent to capture an unmanned nuclear weapon.
