No way does one EMP blast hobble the entire United States. Maybe 10-20 powerful EMP blasts would
“No way does one EMP blast hobble the entire United States. Maybe 10-20 powerful EMP blasts would”
I’m going to quote something from Department of the Army Pamphlet NO. 50-3 (March 1977) “THE EFFECTS OF NUCLEAR WEAPONS.”
Chapter XI The Electromagnetic Pulse and Its Effects
Subpara 11.15 “For and explosion of high yield at a sufficient altitude, the are covered by the high-frequency EMP extends in all directions on the ground as far as the line-of-sight, i.e., to the horizon........For a nuclear explosion at an altitude of 50 miles, for example, the affected area on the ground would have a radius of roughly 600 miles and for an altitude of 100 miles the ground radius would be about 900 miles. For an explosion at 200 miles above the center of the (conterminous) United States, almost the whole country, as well as parts of Canada and Mexico, could be affected by the high-altitude burst, the damage could conceivably extend to distances from ground zero at which all other effects, except possibley eye injury at night.....would be negligible. Furthermore, because the radiations travel with the speed of light, the whole area could be affected almost simultaneaously by the EMP from a SINGLE(emphasis added) high-altitude nuclear explosion.”
