True, Dora might have been able to fire one as a tactical nuke, but it's range was only about 29 miles, so the crew (and all those closer to the target, seeing as it wouldn't have been right on the front line) would have had some problems with radiation.
What about the giant thing the Russians tested in Siberia in the 50,s or maybe 60's , it was such a blast that I think it scared the crap out of the Russians as much as the Americans who recorded it. Any way it is not there any more. But they are bragging about a rocket that can carry a nuke to London in 13 minutes going so fast that it can't be shot out of the sky, BUT, i bet the Yanks have got one too. Is this a d**k swinging competition?
