MOODY AIR FORCE BASE, Georgia - The military's new weapon is a ray gun that shoots a beam that makes people feel as if they will catch fire.

The technology is supposed to be harmless a non-lethal way to get enemies to drop their weapons.

Military officials say it could save the lives of innocent civilians and service members in places like Iraq and Afghanistan.

The weapon is not expected to go into production until at least 2010, but all branches of the military have expressed interest in it, officials said.

During the first media demonstration of the weapon Wednesday, airmen fired beams from a large dish

An unidentified airman looks over the military's Active Denial System, a non-lethal ray gun that was demonstrated at Moody Air Force Base, Ga. The system shoots a beam of energy that makes people feel they are about to catch fire.

The crew fired beams from more than 500 yards (450 meters) away, nearly 17 times the range of existing non-lethal weapons, such as rubber bullets.

While the sudden, 130-degree Fahrenheit (54-degree Celsius) heat was not painful, it was intense enough to make participants think their clothes were about to ignite.


"This is one of the key technologies for the future," said Marine Col. Kirk Hymes, director of the non-lethal weapons program which helped develop the new weapon. "Non-lethal weapons are important for the escalation of force, especially in the environments our forces are operating in."

The system uses millimeter waves, which can penetrate only 1/64th of an inch of skin, just enough to cause

discomfort. By comparison, common kitchen microwaves penetrate several inches of skin.
The millimeter waves cannot go through walls, but they can penetrate most clothing, officials said. They refused to comment on whether the waves can go through glass.

Two airmen and 10 reporters volunteered to be shot with the beams, which easily penetrated various layers of winter clothing.
