World War III, The 36-Hour War of 1948

I would also assume those underground rocket-launching site and atomic bomb factory's are primary located in Colorado, Arizona, Nebraska, North Dakota, South Dakota, Montana, Wyoming and other western states away from heavily populated cities as the missile silos that are used today.

I do wonder if the interceptor rockets are also fired from the underground rocket-launching site and atomic bomb factory's ore that they have their own dedicated underground rocket-launching sites.

it is better that they have their own underground rocket-launching sites because switching every time from interceptor rockets to nuclear rockets and back if needed takes time, some thing they most likely did not have during the 36-Hour War.

They unlike the underground rocket-launching site and atomic bomb factory's who are located in the center of the United States will be located most likely at the coast so they can intercept enemy nuclear rockets coming in.

That is true i also can believe that by the end of the 36-Hour War the underground rocket-launching site and atomic bomb factory's will be the only nuclear arsenal the United States has left as the enemy most likely has targeted Strategic Air Command
(SAC basses across the country.

Also the United States has go more bombers in the form of the Boeing B-29 Superfortress and the Convair B-36 Peacemaker (flew in 1946 thus in service in 1948) as it main bombers while the enemy (lets not kid our self it is the Soviet Union) only has reverse-engineered copy of the Boeing B-29 Superfortress called the Tupolev Tu-4 in its innovatory.

But the Soviet Union is much larger, plus if the enemy has their first launch sites located in equatorial Africa it will take some time by the United States to react that the attack did not come directly from the enemy homeland but from secret rocket-launching sites.
