JF Ptak Science Books Post 1527 Part of the Atomic and Nuclear Weapons series
[Source: Conelrad blog and also at the website]
I stumbled on this bombing of Brooklyn article at the excellent Conelrad website--it is an excellent addition to my slight collection of vintage depictions of American cities being nuked. As part of the necessary scare tactics in the pursuit of the arms end of MAD, the destructive power of these weapons were shown against a background that Americans could readily understand. Thinking of atomic and then nuclear holocaust in terms of multiple units of Hiroshimas and Nagasakis was one thing--showing the effects of these weapons on an American grid was something else.
This next graphic shows the difference in destructive capacity of an atomic bomb (small circle beneath an air-burst detonation) and a hydrogen bomb (the large circle showing area of total destruction, which in this case would be about 50 square miles) on the city of Chicago.

The next image is much like the preceding, only showing a profile of Manhattan and the difference between the explosions of a Hiroshima bomb and a hydrogen bomb (of 20 megatons).

But don't worry, even if the Chicago and Brooklyn and New York and so on were destroyed, the U.S. Navy would survive, which would be either great or horrible if you were a sailor:]
And as usual, the point is made with one weapon being detonated, rather than the x-number that would actually be deployed. Depicting, say, 10 weapons being used against these cities--while being a more accurate portrayal of what nuclear war might look like--might have looked like something beyond the usefulness of propaganda.
