The British also had about a few dozen warheads and several hundred decoys aimed at Moscow starting in the early 1980s. This was actually pretty sensible: the British wanted an independent deterrent, and with a small force, their solution was to deter the USSR by making sure Moscow would be destroyed. The large number of warheads and decoys was needed to guarantee success against the Soviet missile defense system around Moscow. Smaller players with their own arsenals can complicate things considerably. A major problem when trying to decode nuclear war strategy is that the rational thing to do after the missiles have started flying is different from the rational thing to threaten beforehand. If your goal is nuclear war, you want to threaten the enemy with complete and utter destruction from which they will never recover. Once it starts, you want to focus on the enemy's ability to attack you further, and probably ignore the enemy's civilian population and infrastructure. But it's hard to present the "total destruction" option as a credible threat unless you actually set up your forces to go through with it.

Of course the UUSR government would have evacuated and dispersed into remote outposts, just as the US and UK planned to. (Although lacking space and possibly security, it's not obvious the UK government centres would have survived for long.) A more challenging question is - what happens when you get hundreds of warheads detonating in a small area? At a guess that number of explosions would punch its way down into the bedrock. It might even leave a lake of molten crust that would take years, if not decades, to cool. Detonations in seismic areas might trigger huge earthquakes. (SF would be a very bad place to be.) Whatever the outcome, it's a fair guess there would be unplanned consequences of all kinds. Most would be very negative, which makes rational (?) planning difficult.

  I can only guess that the initial explosion(s) would knock out the systems on ones coming after, so a huge percentage of them would be dead on arrival, unless they were decently spaced out, or somehow all arrived and detonated at the same time. (I guess explosion interference from previous explosion is a serious topic of research when it comes to nuclear warfare, if anyone has any good reading material on this please post)

    Your guess is correct! See: https://en.wikipedia.org/wiki/Nuclear_fratricide https://en.wikipedia.org/wiki/Nuclear_fratricide Key quote: "It appears that two weapons targeted on a silo must arrive at least ten seconds apart to avoid fratricidal fireball effects, and less than one minute or more than one hour apart to avoid fratricidal nuclear dust cloud effects."
