Previous posts have described the count of nuclear weapons in the U.S. inventory and how they are deployed. Future posts will dive into the inventory of other nuclear powers. Plan to have some discussion of the U.S. inventory at various times in the past.
Reading the various articles made me wonder how many weapons are available in what time frame.
For example, the Minuteman-III loaded with the Mk12A reentry vehicle can carry 3 warheads but are only loaded with 1. It would take months to reconfigure 200 missiles with another 400 warheads.
Of the 12 Ohio-class subs not in refueling, 8 are usually at sea with 4 of those on-station. The other 4 are hours or days away from their assigned station.
There are guessed 200 ALCMs at Minot and 100 gravity bombs at Whiteman which would take a fair amount of time to load. It would take an even long time to transport the remaining 550 weapons out to Minot and Whiteman.
So, I took a wild guess at how many weapons are available to the president immediately and long it would take to get the remaining inventory on line.
