EMPs: The Next Great Threat to America

Posted By Jackson Marsteller On November 23, 2011 @ 1:50 pm In Security | Comments Disabled

This week at The Republican National Security Debate [1], hosted on CNN [2] by The Heritage Foundation and the American Enterprise Institute, an electromagnetic pulse attack (EMP) was mentioned as one of the most important national security issues that is not discussed often. This is true. Despite the gravity of the threat, the United States remains unprotected from the effects of an EMP.

An EMP [3] is a high-intensity burst of electromagnetic energy caused by a rapid acceleration of charged particles. The EMP would disrupt all electronic devices within its zone of impact. It would burn circuits and immobilize electronic components and systems. It addition, the EMP would flow through electricity transmission lines and would damage distribution centers and power lines.

Detonating a singular nuclear weapon at a high altitude can create an EMP large enough to envelop the entire continental United States. The nuclear weapon could be delivered by a long-range ballistic missile from Iran, China, Russia, or North Korea. Even a short-range nuclear-tipped missile launched off of the U.S. shore could cause a devastating EMP effect.

But not all causes of an EMP are man-made, as it can also be caused by a large solar flare called the Carrington effect. The last time such an event happened on a larger scale, it shocked telegraph operators unconscious and their machines caught on fire as the electromagnetic forces from the flare surged through the lines.

The effects of an EMP on today’s society would be even more devastating. According [4] to Heritage’s James Carafano, “communications would collapse, transportation would halt, and electrical power would simply be nonexistent. Not even a global humanitarian effort would be enough to keep hundreds of millions of Americans from death by starvation, exposure, or lack of medicine.”

There are some simple steps that can be taken to prevent against the crippling effects of an EMP attack. First, the U.S. needs to build and adequately fund a robust missile defense system [5] composed of Aegis ballistic missile capable ships, and Aegis Ashore, the land-based ballistic missile component. Second, both the public and private sectors should harden vital infrastructure [6] to make it more resilient and resistant to the EMP—to hedge against an attack or prepare for a solar flare. Third, the U.S. should develop a national plan to respond to EMP emergencies. This would involve educating federal, state, and local officials along with the public about the risks and response options.
