Secret "e-bomb" _ which can disrupt electronics _ appears ready for battlefield test in Iraq
By Matt Crenson; Associated Press Writer
Military analysts predict U.S. forces will test a new "E-bomb" during the expected invasion of Iraq as part of a 21st century blitzkrieg designed to render Iraqi leader Saddam Hussein's forces blind, deaf, dumb and incapable of retaliation - electronically.
The highly classified bombs creates a brief pulse of microwaves powerful enough to fry computers, blind radar, silence radios, trigger crippling power outages and disable the electronic ignitions in vehicles and aircraft.
"They would be useful against any adversary that is dependent on electronic systems," said Loren Thompson, a defense analyst at the Lexington Institute, a think-tank based in Arlington, Virginia.
In modern warfare, electronics undergird virtually every weapon more sophisticated than a rifle or hand grenade. For that reason, Air Force scientists have worked for decades on a practical way of producing powerful but brief pulses of microwaves that can incapacitate electronic equipment without damaging buildings or harming people.
Officially, the Pentagon does not acknowledge the weapon's existence. Asked about it at a March 5 news conference at the Pentagon, Gen. Tommy Franks said: "I can't talk to you about that because I don't know anything about it."
However, military analysts say a number of unclassified documents suggest that such a device is ready for the battlefield.
"There's been a lot of discussion behind closed doors in the Pentagon and in the trade press that these things are now being tested," Thompson said.
According to a 2000 report by Air Force Col. Elaine M. Walling, scientists at Kirtland Air Force Base in New Mexico have created microwave sources that generate up to 10 times the amount of energy that Hoover Dam produces in a day.
Such powerful pulses can incapacitate electronic equipment without damaging buildings or harming people, making them an attractive weapon whenever civilian casualties are a concern.
In laboratory tests, microwave pulses can melt silicon chips, pushing their circuits far beyond their capacity to conduct electricity. But on the battlefield, even the most impressive E-bomb's effects rapidly diminish with distance. Although E-bombs' capabilities are classified, military analysts believe their range is a few hundred yards (meters) at most.
That relatively short range decreases the odds that hospitals, orphanages and other civilian infrastructure will be affected, unless they are directly adjacent to or networked with military targets.
"I think it is almost always more humane to use this compared to a conventional weapon," Thompson said.
The bombs' effects are also hard to predict, analysts say. The surge of electricity produced by a microwave pulse could go directly to the nearest bank of military supercomputers, or it could just as easily be shunted harmlessly into the ground.
"The effects are hard to focus. The moment the energy is absorbed into wiring or other electrically conductive material, you don't know where it's going to go," Thompson said.
Those uncertainties and others may prevent E-bombs' playing a major role in the anticipated U.S. offensive against Iraq, said Lt. Col. Piers Wood, a military analyst at the defense policy think-tank globalsecurity.org.
"There will be a few commanders who will see these and get to try them out," Wood said. "We're not talking about arsenals of these things."
Defense experts are particularly eager to see if E-bombs can reach into deep underground bunkers that could otherwise be neutralized only by tactical nuclear weapons. By shutting off the electricity, a microwave weapon could render a bunker uninhabitable by disabling lighting, security systems, ventilation and computers.
Evenually, Wood said, other nations may acquire high power microwave weapons; American forces, which depend so heavily on technology, would be particularly vulnerable to them.
He predicted that soon all military electronics will have to be protected from high power microwaves by metal casings, with sophisticated circuit breakers connected to any incoming wires.
