“It’s categorized as IW, which stands for Information Warfare. Our first experience with it occurred during Desert Storm in Baghdad in early 2001. We demonstrated that with the application of air power this was the most practical means of crushing Saddam Husain’s Command and Control informational systems. Electromagnetic bombs were built and used extensively for this purpose. Such bombs were characterized by the creation of short bursts- and I’m talking nanoseconds here- of intense electromagnetic pulses moving away from the source. The detonation had to be high above the target with an ever intensifying effect. This electromagnetic pulse is like an electrical shock wave which is similar to lightening only far more intense. It creates a field of electrical energy strong enough to produce transient voltage. It’s called variable kilovolts on exposed electric conductors, such as wires or conductive tracks on printed circuit boards, and the effect is melting them beyond recovery or repair.
“Commercial computer equipment is especially vulnerable to electromagnetic pulse because it’s all built with high-density metal oxide semi-conductor devices which are unshielded. Even if the pulse itself was not strong enough to completely destroy the targeted equipment, the equipment’s own internal power supply would be damaged sufficiently to complete the destructive process.”
Jack refilled Danny’s coffee cup from the carafe.
“Couldn’t the computers be shielded by the lead lining of the computer housing?” asked Sam.
“Good question. Not really,” replied Danny. “Any cables running into and out of the computers act as antennae- in effect, guiding the high voltage transients into the equipment by its own proprietary wiring.”
Jack asked, “Are standard computers the only electrical equipment that is vulnerable to this?”
“No. Any equipment that relies on programmed devices is highly susceptible, such as data processing systems, communications systems, displays, industrial control applications,all signal processors including road and rail signaling, electronic flight controls and digital engine control systems found in all types of vehicles, are all extremely vulnerable to EMP effect.”

“What else would be affected?” asked Sam, gravely.
“Oh God,” replied Danny, sullenly. “High frequency transistors and diodes found in all types of communication equipment would be easily destroyed. This includes radar and electronic warfare equipment, missile guidance systems, satellites, microwave, VHF, UHF, HF and even low-band communications equipment such as that used by police, fire departments and all EMS services, and all regular AM and FM radio and television communication would be gone as well as all telephones, both landline and cellular. The internet, also, would be toast.”
“It sounds to me,” said Jack, “That a detonation of such a device high above a major American city would completely destroy the ability of that city to function.”
“For all intents and purposes, Jack, it would bring us back to the time before Mr. Ben Franklin invented electricity. Yes, such a city would cease to function because everything we do today involves electricity and computers. The explosions would destroy all electronic infrastructure. We’d be back to using horses for everything and pumping water out of the ground by hand, assuming you could even find a hand pump today.”
“This is all very hard to believe,” commented Sam. “But it would only affect one city, like maybe Cleveland or someplace, but the whole country wouldn’t be involved, right?”
“Well,” said Danny. “Your hypothesis presumes that detonations wouldn’t take place over dozens of American cities simultaneously. What if that was the game plan?”
“Good Lord!” exclaimed Jack.
