“You have to feel the ray gun to believe it,” says 60 Minutes correspondent David Martin, speaking about a non-lethal weapon the Pentagon has developed, “and there’s only one way to do that.”
Martin was reportedly “zapped” 17 times for this piece, demonstrating the effects, as well as the possibility that a person could reduce the impact with shields of various materials.
“The gun is really an antenna which shoots out this very high-frequency radio beam that penetrates the skin to a depth of 1/64 of an inch, which is just deep enough to hit the nerves,” says Martin. “And it creates this instantaneous sensation of heat which makes anyone who is hit with it try to get out of the way as fast as possible.
“And the second you do get out of the way, the pain goes away,” Martin continued. “And the point is that this gun, which has a range of roughly half a mile – the exact range is classified – can make you stop whatever it is you’re doing.”
It seems that is the intended benefit of this weapon, which Martin says causes the sensation of being scalded with hot water.
He asks, “How many innocent lives have been lost by someone approaching a check-point and not heeding the warning signs that American soldiers were giving them …? Now you have this gun. If you shoot that ray gun at someone and they keep coming you can safely assume that they have evil intent and have cleared the way to use more lethal force, which would be their rifle.”
HOW HEAT-RAY GUN WORKS
1 360-degree operation for maximum effect
Antenna, linked to transmitter unit, can be mounted on vehicle
Automatic target tracking
2 Antenna sealed against dust and can withstand bullet fire
3 Invisible beam of millimetre-wave energy can travel over 500m
4 Heat energy up to 54C (130F) penetrates less than 0.5mm of skin
Manufacturers say this avoids injury, although long-term effects are not
The US military has given the first public display of what it says is a revolutionary heat-ray weapon to repel enemies or disperse hostile crowds.
Called the Active Denial System, it projects an invisible high energy beam that produces a sudden burning feeling.
Military officials, who say the gun is harmless, believe it could be used as a non-lethal way of making enemies surrender their weapons.
Officials said there was wide-ranging military interest in the technology.
“This is a breakthrough technology that’s going to give our forces a capability they don’t now have,” defence official Theodore Barna told Reuters news agency.
“We expect the services to add it to their tool kit. And that could happen as early as 2010.”
‘Blast from an oven’
The prototype weapon was demonstrated at the Moody Air Force Base in Georgia.
A beam was fired from a large rectangular dish mounted on a Humvee vehicle.
The beam has a reach of up to 500m (550 yds), much further than existing non-lethal weapons like rubber bullets.
It can penetrate clothes, suddenly heating up the skin of anyone in its path to 50C.
But it penetrates the skin only to a tiny depth – enough to cause discomfort but no lasting harm, according to the military.
A Reuters journalist who volunteered to be shot with the beam described the sensation as similar to a blast from a very hot oven – too painful to bear without diving for cover.
Military officials said the weapon was one of the key technologies of the future.
“Non-lethal weapons are important for the escalation of force, especially in the environments our forces are operating in,” said Marine Col Kirk Hymes, director of the development programme.
The weapon could potentially be used for dispersing hostile crowds in conflict zones such as Iraq or Afghanistan.
It would mean that troops could take effective steps to move people along without resorting to measures such as rubber bullets – bridging the gap between “shouting and shooting”, Col Hymes said.
A similar “non-lethal” weapon, Silent Guardian, is being developed by US company Raytheon.
