the idea is simpel
your build a weapon, which could destroy all life on the Earth.
and used it to defend your self
"Try to attack me, Its shall destroy the world"
look like a wacky Sci-fi Idea from Dr Strangelove...
But Its a REAL idea by strategist Herman Kahn and risk analyst Ian Harold Brown from RAND corp !
a computer with sensors linked to a stockpile of dirty H-bombs.
if the computer recognizes a Nuclear Attack, it detonate the H-bombs
and Radioaktiv Fallout and Nuclear winter do the rest
lucky for us the U.S. or Soviets never bulid one of these
But wat If ?
how looks a Cold War with Doomsday Devices ?
like no Cuba missile Crisis but a "Doomsday Surprise" in 1962
how to maintenance and how they are defused them after Cold War ?
the Device operate fully automatically and has a Fail Safe against defuse !
Real Doomsday proposals
USAF proposed the use of ground launch Orion (the Nuclear Puls Engine)
Payload a 1500 metric Tons heavy H-bomb, that would be 1-2 giga ton TNT
PLUTO / SLAM can be also consider as Doomsday weapon
It a nucklear power Ramjet Cruise missle with 20 H-bomb
after the mission, they flights for months in Soviet airspace producing radioaktive fallout
The Soviet Union had plans for the World largest Kobalt Bomb
build inside a Cargo ship means a bomb of weight of 10000 metric Tons !
building such big H-bomb is no problem, so long they is fuel, the Fusion reactions goes on.
