A new congressional report contends that a North Korean electromagnetic pulse (EMP) attack on the U.S. would ultimately wipe out 90 percent of the population.
To date, most discussion concerning the North Korean threat has been on whether the rogue state can accurately hit U.S. cities with its ICBMs. But in an EMP attack, such accuracy is not necessary because the pulse radius would be so large, says Peter Vincent Pry, who recently testified about the EMP threat before a congressional Homeland Security subcommittee. His conclusions are that such an EMP attack would wreak havoc across the whole of the continental U.S.
Unlike a conventional ICBM which launches and then goes into a suborbital flight before re-entering Earth’s atmosphere, an EMP warhead need not re-enter Earth’s atmosphere before exploding hundreds of kilometers above its target. Super-EMP weapons are designed to produce a high level of gamma rays, which generate the sort of high-frequency electromagnetic pulse that is most damaging to the broadest range of electronics, the report concludes.
And if the EMP device just happens to be part onboard an orbiting satellite, North Korea need only detonate the device remotely via encoded signal. Pry, Chief of Staff of the now de-funded Congressional EMP Commission, told me that at an altitude of 300 kilometers, the resulting electromagnetic pulse would affect all 48 contiguous states.
