After decades of being rejected, microwave weapons are beginning to be viewed as a serious military threat, prompting the Department of Defense to issue a request to equip U.S. soldiers with detectors for what it has. called “a growing threat on the battlefield”.
The weapons, some of which cause burning sensations, have already been considered for use on American soil. In June, a federal police officer requested a truck-sized vehicle microwave heat ray disperse the Black Lives Matter protests. The Trump administration considered using this same device against asylum seekers in 2018.
Now the Department of Defense wants American soldiers to be equipped with microwave weapon detectors. This was exhibited in a December 9 contract solicitation for “A small size, low weight, low cost portable radio frequency (RF) weapon exposure detector”, specifying high frequency microwaves, from the Department of Defense Health Program Defense.
Defense Ministry interest in microwave weapon detection comes Israel, China and Russia are said to be inventing their own versions of a microwave heat ray “Active refusal system”That the United States pioneered two decades ago. The United States continues to develop the technology: an Air Force research laboratory deploys a “electromagnetic counter-swarm weapon, Called THOR, to fry drones in mid-flight. A prototype Navy microwave weapon mounted on a standard gun holder was unveiled in 2018. The need to disable drones has become more real with the autumn war between Azerbaijan and Armenia, which the former won with drone fleets decimating the latter’s defenses.
Then, in December, a new report suggested that these weapons could cause neurological damage. National Academies of Science, Engineering and Medicine criticized report suggested that guns were the “most plausible” explanation for the puzzling neurological damage seen in at least 15 diplomatic personnel and their families in Cuba in 2016 and 2017.
“Without known models of [radiofrequency] injury to guide the diagnosis, it will be difficult to differentiate [microwave] injuries from other common sources of illness and injury such as heatstroke, ”explains the defense agency’s microwave weapon detector. program request, which ends in about two weeks. “This ambiguous symptomatology is compounded by the transient nature of RF energy. Without a sensor, it is possible that no residual evidence of RF attack is available.
The Defense Ministry declined to comment on the detector’s contract. However, experts contacted by BuzzFeed News suggested that the growing military interest in microwave weapons could stem from the advent of drone weapons and the NASEM report. The technology, they added, is remarkable as a new battlefield concern in the 21st century.
“I guess although the United States has never deployed these weapons in a theater of war, there is a fear that other actors will,” said Andrew Wood of the Australian Center for Electromagnetic Bioeffects Research. by e-mail. They can easily be concealed behind fabric screens, he added, so that US military personnel experiencing burning sensations, for example, might need a detector to know if someone else is point a microwave gun at them.
The demand for the contract for a portable sensor that can fit in a rifle magazine pouch and can be attached to a vest also indicates concerns over accidental microwave exposure by workers at the military test site, said the environmental epidemiologist Marloes Eeftens of the Swiss Tropical and Public Health Institute. BuzzFeed News by email.
Despite the stinging sensation one can experience when in the beam of a “heat ray-like” weapon, Eeftens warned that it would be difficult to determine if a concentrated microwave field was. to blame. “You will come out without marks, so it’s hard to objectively determine if and how much someone has really been exposed,” she said.
There are detectors for other types of radio waves besides microwaves described in the Department of Defense tender, Paul Elliot of Magnetic Sciences Inc. in Acton, Massachusetts told BuzzFeed News. They are generally intended for people who work with electronics.
“The things we sell are the size of bricks, or at least half a brick,” he said. “You wouldn’t wear one.”
While microwaves that induce high temperatures, like those found in ovens, can cook foods and cause burns, the question of whether neurological disorders health effects may result from less potent a long lack of evidence and has been subjected to the types of conspiracy theories seen today on 5G cellphones.
US Air Force experiments set limits on human microwave exposure in the 1970s during studies of the electromagnetic pulses observed during nuclear explosions. These standards have since been widely adopted, but a NATO Technical Report 2018 called these limits scientifically unwarranted, saying they were not supported by any experience showing injury. A report by French researchers Last year that low-power pulsed microwaves were associated with cancer and behavioral changes in rats once again raised the issue of health effects, especially with systems such as THOR now being considered for use in the field against drones.
“I don’t expect major safety concerns for people in the beams, but on the other hand, the amount of research on the biological effects of these pulses is limited,” said bioengineer Ken Foster, of the University of Pennsylvania. “If the military wants to deploy these weapons, it would do much better to do some good security studies.”
