An electromagnetic pulse attack on America could completely disable our defense systems, leaving the U.S. in a technology world equivalent to the stone age. IF such an attach were to happen we wouldn’t even be able to figure out who attacked us.
An EMP weapon would take out electronic devices including targeting, communications, navigation and sensor systems, and it would cripple our ability to defend ourselves against a land invasion. The more we use electronic devices, the more dependent we are on them, and the more vulnerable we are to this sort of threat.
What is an EMP?
An EMP is a blast of electromagnetic energy that can disrupt — if not destroy — electronic devices within an affected area. You can’t smell, taste or feel EMP radiation, which can be unleashed by nuclear explosions as well as by solar storms and devices.
From a low-level electromagnetic pulse that could jam electronics systems temporarily to megabursts that would utterly fry electronic equipment, any sort of pulse would be bad news.
Planes could fall from the skies, transportation could come to a screeching halt, water and sewage systems could suddenly cease to work. An EMP can destroy electrical components permanently; they could not be repaired.
