ELECTROMAGNETIC PULSE (EMP): THREAT TO CRITICAL INFRASTRUCTURE
113th Congress (2013-2014)
Currently the nations of Russia and China have the technology to launch an EMP attack, and we have speculated that Iran and North Korea may be developing EMP weapon technology. This is why we must remain vigilant in our efforts to mitigate the effects of an EMP attack.
Iran—the world's leading sponsor of international terrorism—in military writings openly describes EMP as a terrorist weapon, and as the ultimate weapon for prevailing over the West: ``If the world's ´ industrial countries fail to devise effective ways to defend themselves against dangerous electronic assaults, then they will disintegrate ´within a few years . . . American soldiers would not be able to find ´food to eat nor would they be able to fire a single shot.’’
The threats are not merely words. The EMP Commission assesses that Russia has, as it openly declares in military writings, probably developed what Russia describes as a ``Super-EMP’’ nuclear weapon— specifically designed to generate extraordinarily high EMP fields in order to paralyze even the best protected U.S. strategic and military forces. China probably also has Super-EMP weapons. North Korea too may possess or be developing a Super-EMP nuclear weapon, as alleged by credible Russian sources to the EMP Commission, and by open-source reporting from South Korean military intelligence. But any nuclear weapon, even a low-yield first generation device, could suffice to make a catastrophic EMP attack on the United States. Iran, although it is assessed as not yet having the bomb, is actively testing missile delivery systems and has practiced launches of its best missile, the Shahab-III, fuzing for high-altitude detonations, in exercises that look suspiciously like training for making EMP attacks. As noted earlier, Iran has also practiced launching from a ship a Scud, the world's most common missile—possessed by over 60 nations, terrorist groups, and private collectors. A Scud might be the ideal choice for a ship-launched EMP attack against the United States intended to be executed anonymously, to escape any last-gasp U.S. retaliation. Unlike a nuclear weapon detonated in a city, a high-altitude EMP attack leaves no bomb debris for forensic analysis, no perpetrator ``fingerprints.’’
