High Power Microwaves To Be America’s Secret Weapon in War

January 19, 2003

Every war has its wonder weapon. In Afghanistan, it was the Predator, the unmanned drone that would loiter, invisibly, over the battlefield before unleashing a Hellfire missile on an unsuspecting target. The Gulf War marked the debut of precision-guided munitions, and in Vietnam helicopters came of age. World War II gave us the horror of nuclear weapons, and World War I introduced the tank. If there's a second Gulf War, get ready to meet the high-power microwave.

HPMs are man-made lightning bolts crammed into cruise missiles. They could be key weapons for targeting Saddam Hussein's stockpiles of biological and chemical weapons. HPMs fry the sophisticated computers and electronic gear necessary to produce, protect, store and deliver such agents. The powerful electromagnetic pulses can travel into deeply buried bunkers through ventilation shafts, plumbing and antennas. But unlike conventional explosives, they won't spew deadly agents into the air, where they could poison Iraqi civilians or advancing U.S. troops.

The HPM is a top-secret program, and the Pentagon wants to keep it that way.
