Nuclear warfare was the nature of the threat during the cold
war. Today, cyber warfare is replacing the traditional types of military
engagement between countries with cyber capabilities. Having optimal national
security requires an ability to predict the next emerging and disruptive
technologies, and the capability to develop weapons and defense systems for
these threats. As electronics become ever more integrated into the functioning
of daily life, electronic weapons with the capability to disrupt society will
become and increasing threat.
Electronic weapons function by releasing electromagnetic
pulses into the atmosphere. Most people may be aware of the electromagnetic
pulse that can be generated by a nuclear bomb. There has been much hysteria
surrounding the results of a successful EMP attack that could destroy
electronics that run our hospitals, transportation systems, satellites, and
communication systems. How could society function if the world were to suddenly
go dark?
These new type of weapons, already being developed by key defense
contractors like Raytheon, are designed differently. These devices are pointed
energy systems that focus a large amount of electromagnetic energy on a single
point instead of releasing it as a spread in the atmosphere. The literature
on these types of weapons suggests that they would only do significant
damage to electronics and not to humans. Though it is true that the
electromagnetic energy generated from common devices, such as cell phones, do
not cause bodily harm, it would seem unlikely that such a concentrated amount
of energy couldn’t do damage to the human body.
Nonetheless, these devices are already being developed and
implemented by the United States Military. Planes such as the F-35 and Bowing
Growler use this technology for defensive and offensive purposes respectively.
Ships are being fitted with active electronically scanned array (ASEA) guns
that have to capacity to disrupt a swarm of 30 boat motors. The explosive payload
on missiles has been replaced with this type of technology to target
electronics as well.
Besides these common military applications however, Raytheon
has developed the most interesting implementation of electromagnetic weaponry.
The Active Denial System (ADS) is designed to heat the moisture in a persons
skin, resulting in a reaction to flee the area. These systems were even shipped to Iraq, but were never
implemented in combat before they were sent home.
There have also been many developments in ways to defend against an electronic attack. Most notably would be the implementation of Faraday cages to shield any emittance of electromagnetic energy by using conductive materials. Planes can be fitted with faraday cage shields in order to thwart ASEA attacks. Even materials such as concrete are being added with conductive material to provide potential shields for buildings.
There are a variety of ethical issues surrounding the use of
these weapons. Until studies can be conducted that conclusively show high
levels of electromagnetic radiation can cause damage to humans (such as cancer
development) these devices will continue to be marketed as the newest and best
way to engage in warfare with few casualties. For the time being though, most
of these weapons will be designed to target electronics and not humans as a result of their negative, sci-fi personification by most of the general public.
