I am still curious what the experts say, but my educated guess is, that concerning the United States we would end up with 10,000 warheads exploding on its soil.
That is 1 NUDET per 962 km². Is that a lot or not?
300 nukes on the UK would mean an average of 1 NUDET per 816 km², a rather similar result.
Assuming that 1MT bombs are used.
We know that the destructive radius of a 1MT bomb is roughly 20km and I even define destruction as encompassing a knocked out windows here.
A = pi x r²
A = 3.1416 x 20²
A = 3.1416 x 400
A = 1256.64 km²
Mathematically therefore, 10 000 nukes on the USA or 300 nukes on the UK would be sufficient to create a lot of destruction in the entire areas of said countries.
But we do know however that megaton range weapons have not been the main weapons used, at least in Europe (the USA will be hit by higher yield weapons however, as ICBM warheads are larger and more powerful on average). We also know that a significant amount of targetting would be redundant in case of failures and that some targets might be hit as much as ten or fifteen times (New York).
Consequently, and especially in the light of the fact that I have been using the higher end of the estimate for the damage radius, we can reliably expect that mathematically large areas of Britain, the United States or for that matter Germany, will be free of blast and thermal damage and will only have to content with fallout.
I will also restart that debate, but we must not forget that even if the USSR has 40 000 warheads in storage, it does not have enough missiles, planes and submarines to deliver even a third of this stockpile.
For weeks now, I have been reasearching the net to find an old interview I read in "Der Spiegel" about a decade ago. My attempts, however, were futile. So, without evidence, I have to bring the key points back from memory.
The paper interviewed an US military official who had taken part in the post-cold-war "cleaning up" of nuclear target lists during the 1990s.
He stated that most of the "streamlining" was simply being accomplished by taking redundant or targets of minor importance from the list. As an example for the latter he claimed "bridges in Siberia". From his point of view a clear example of the overkill of the late cold war. "There were so many warheads available, we hardly could imagine what to do with them."
He also confirmed the interviewer's suspicion that multi-targeting of important cities in the Soviet Union went in some cases beyond ten warheads. He didn't confirm the interviewer's suspicion that it was the Ukrainian capital Kiew.
Well, these are about the parts of it I remember. If anybody is more lucky with providing the interview... good luck.
I think that the overtargeting of cities is far far more likely that hiting up bridges in the middle of the Kolyma in my opinion. Moscow has likely recieved a hundred warheads from all the NATO allies. The same story is true for St Petersburg and certainly for Kiev as well. One thing worth remembering as well, is that the Soviet Union had a penchant for building up huge complexes and huge factories to meet the needs of their planned economy. The giant lorry factories in the Urals are the best example of this. Said facilities constitute targets in themselves. Whereas ten smaller factories are not necessarily strategic targets on their own.
Oh, I don't know, he's been pretty civil so far. Besides, constructive criticism is good for keeping people on their toes. If everyone were going "great job" then it'd be easy for one to start believing in their own hype, and then things go downhill. For examples of this, see: Slade, Stuart "TBO, Salvation War".
I have been the first one on the various Protect and Survive threads to criticise and point out what I felt were gaps or omissions. I was however always careful to back up my assertions with arguments, chiefly numbers where possible and sometimes links to other studies made by people who had far more time on their hands than I do now.
Someone involved in emergency planning in Britain (corditeman) also made numerous criticism and felt that in some cases Macragge timeline was too pessimistic, especially with regards to the mutated babies (something I too feel won't happen on a massive scale).
Having worked in SAC is not an automatic badge of expertise, especially if said work has bene very compartementalised and very narrow. The fact that someone works say in the HR department of an oil refinery, does not mean that this person is going to be an expert in oil refining or even to know anything about it. Similarily the fact that you know to operate the refinery and how the various processes work, does not mean that you will be the best person to hire new workers, or to decide where and when the products should be sold.
There is a saying which says that the map is very different from the reality on the ground. A 1MT nuclear bomb will have different effects depending on whether or not it has been dropped on London, Paris, Los Angeles or Kinshasa. In particular, there is a lot of evidence ponting out to the fact that an Hiroshima sized bombs would be far less destructive if dropped on a European city. Japanese houses are built of wood and paper, European ones of stones and cement ...
