> And what of the submarine? Very good point. When I used to work in that stuff, it was assumed that once know where a sub was, it was easy to kill it -- just pop off a nuke and let the resulting pressure wave in the water crush the hull of the sub. Sounds like the Soviet nuke torpedo was a very low yield nuke -- if the sub would survive, then the explosion would not have been big enough to have been a trigger of full nuke war like, say, a 10 megaton nuke over a major city.
