It seems that when a nuke is detonated it produces a rather powerful EMP which could fry the guidance systems of nearby missiles. Question: Is there a known ratio of yield to effective guidance system frying radius?
Depends on how hardened the guidance system is. You can harden a system to any degree you like, so there's no one radius.
OK coupl'a questions 1)Just how hardened can a guidance system be if it requires gps inputs? 1a)How hardened can a guidance system be if you forsake accuracy with a programmed course? 2)what power emp would be expected over the range of 17 kilotons to 100 megatons eg 2etc.)could a 17k fry a car's electrical system at 1 mile? 5 miles? etc... could a 100m fry a car's electronics at 100 miles? 200 miles? how about the electricity grid? Power needed for emp to disable the switches?
this is quite a good article on EMP weapons. http://www.globalsecurity.org/military/library/report/1996/apjemp.htm
