Raytheon has developed an active denial system (ADS) which behaves much like a ray gun. It projects microwave-like radiation for distances of more than 500 yards, creating an excruciating, full-body burning sensation in anyone caught in its beam. The millimetre-wave rays penetrate skin to a depth of about 1/64in but cause no permanent damage, according to Raytheon, the system’s US-based maker. Prototypes of the weapon, called Silent Guardian, weighed about three tons and were mounted on trucks. Both the British and U.S. governments are evaluating it for use by police and military.
The Silent Guardian™ protection system by Raytheon is a revolutionary less-than-lethal directed energy application that employs millimeter wave technology to repel individuals or crowds without causing injury. The system provides a zone of protection that saves lives, protects assets and minimizes collateral damage. Silent Guardian produces precise effects at longer ranges than current less-than-lethal systems and provides real-time ability to establish intent and de-escalate aggression. Various commercial and military applications include law enforcement, checkpoint security, facility protection, force protection and peacekeeping missions. The system is available now and ready for action.
