The Pentagon's quest for
nonlethal arms is amazing. But is it smart?
(From US News)
BY DOUGLAS PASTERNAK
Tucked away in the corner of
a drab industrial park in Huntington Beach, Calif., is a windowless,
nondescript building. Inside, under extremely tight security, engineers and
scientists are working on devices whose ordinary appearance masks the oddity
of their function. One is cone shaped, about the size of a fire hydrant.
Another is a 3-foot-long metal tube, mounted on a tripod, with some black
boxes at the operator's end. These are the newest weapons of war.
For hundreds of years, sci-fi
writers have imagined weapons that might use energy waves or pulses to knock
out, knock down, or otherwise disable enemies--without necessarily killing
them. And for a good 40 years the U.S. military has quietly been pursuing
weapons of this sort. Much of this work is still secret, and it has yet to
produce a usable "nonlethal" weapon. But now that the cold war has ended and
the United States is engaged in more humanitarian and peacekeeping missions,
the search for weapons that could incapacitate people without inflicting
lethal injuries has intensified. Police, too, are keenly interested. Scores
of new contracts have been let, and scientists, aided by government research
on the "bioeffects" of beamed energy, are searching the electromagnetic and
sonic spectrums for wavelengths that can affect human behavior. Recent
advancements in miniaturized electronics, power generation, and beam aiming
may finally have put such pulse and beam weapons on the cusp of
practicality, some experts say.
Weapons already exist that
use lasers, which can temporarily or permanently blind enemy soldiers.
So-called acoustic or sonic weapons, like the ones in the aforementioned
lab, can vibrate the insides of humans to stun them, nauseate them, or even
"liquefy their bowels and reduce them to quivering diarrheic messes,"
according to a Pentagon briefing. Prototypes of such weapons were recently
considered for tryout when U.S. troops intervened in Somalia. Other,
stranger effects also have been explored, such as using electromagnetic
waves to put human targets to sleep or to heat them up, on the
microwave-oven principle. Scientists are also trying to make a sonic cannon
that throws a shock wave with enough force to knock down a man.
While this and similar
weapons may seem far-fetched, scientists say they are natural successors to
projects already underway--beams that disable the electronic systems of
aircraft, computers, or missiles, for instance. "Once you are into these
antimateriel weapons, it is a short jump to antipersonnel weapons," says
Louis Slesin, editor of the trade journal Microwave News. That's
because the human body is essentially an electrochemical system, and devices
that disrupt the electrical impulses of the nervous system can affect
behavior and body functions. But these programs--particularly those
involving antipersonnel research--are so well guarded that details are
scarce. "People [in the military] go silent on this issue," says Slesin,
"more than any other issue. People just do not want to talk about this."
Projects underway. To
learn what the Pentagon has been doing, U.S. News talked to more than
70 experts and scoured biomedical and engineering journals, contracts,
budgets, and research proposals. The effort to develop exotic weapons is
surprising in its range. Scores of projects are underway, most with funding
of several hundred thousand dollars each. One Air Force lab plans to spend
more than $100 million by 2003 to research the "bioeffects" of such
The benefits of bloodless
battles for soldiers and law enforcement are obvious. But the search for new
weapons--cloaked as they are in secrecy--faces hurdles. One is the
acute skepticism of many conventional-weapons experts. "It is interesting
technology but it won't end bloodshed and wars," says Harvey Sapolsky,
director of the Security Studies Program at MIT. Says Charles Bernard, a
former Navy weapons-research director: "I have yet to see one of these ray
gun things that actually works." And if they do work, other problems arise:
Some so-called nonlethal weapons could end up killing rather than just
disabling victims if used at the wrong range. Others may easily be thwarted
Sterner warnings come from
ethicists. Years ago the world drafted conventions and treaties to attempt
to set rules for the use of bullets and bombs in war. But no treaties govern
the use of unconventional weapons. And no one knows what will happen to
people exposed to them over the long term.
Moreover, medical researchers
worry that their work on such things as the use of electromagnetic waves to
stimulate hearing in the deaf or to halt seizures in epileptics might be
used to develop weaponry. In fact, the military routinely has approached the
National Institutes of Health for research information. "DARPA [Defense
Advanced Research Projects Agency] has come to us every few years to see if
there are ways to incapacitate the central nervous system remotely," Dr. F.
Terry Hambrecht, head of the Neural Prosthesis Program at NIH, told U.S.
News. "But nothing has ever come of it," he said. "That is too science
fiction and far-fetched." Still, the Pentagon plans to conduct human testing
with lasers and acoustics in the future, says Charles Swett, an assistant
for Special Operations and Low-Intensity Conflict. Swett insists that the
testing will be constrained and highly ethical. It may not be far off. The
U.S. Air Force expects to have microwave weapons by the year 2015 and other
nonlethal weaponry sooner. "When that does happen," warns Steven Metz,
professor of national security affairs at the U.S. Army War College, "I
think there will be a public uproar. We need an open debate on them now."
What happened with U.S.
forces in Somalia foreshadows the impending ethical dilemmas. In early 1995,
some U.S. marines were supplied with so-called dazzling lasers. The idea was
to inflict as little harm as possible if Somalis turned hostile. But the
marines' commander then decided that the lasers should be "de-tuned" to
prevent the chance of their blinding citizens. With their intensity thus
diminished, they could be used only for designating or illuminating targets.
On March 1, 1995, commandos
of U.S. Navy SEAL Team 5 were positioned at the south end of Mogadishu
airport. At 7 a.m., a technician from the Air Force's Phillips Laboratory,
developer of the lasers, used one to illuminate a Somali man armed with a
rocket-propelled grenade. A SEAL sniper shot and killed the Somali. There
was no question the Somali was aiming at the SEALs. But the decision not to
use the laser to dazzle or temporarily blind the man irks some of the
nonlethal-team members. "We were not allowed to disable these guys because
that was considered inhumane," said one. "Putting a bullet in their head is
somehow more humane?"
Despite such arguments, the
International Red Cross and Human Rights Watch have since led a fight
against antipersonnel lasers. In the fall of 1995, the United States signed
a treaty that prohibits the development of lasers designed "to cause
permanent blindness." Still, laser weapons are known to have been developed
by the Russians, and proliferation is a big concern. Also, the treaty does
not forbid dazzling or "glare" lasers, whose effects are temporary. U.S.
military labs are continuing work in this area, and commercial contractors
are marketing such lasers to police.
The next debate may well
focus on acoustic or sonic weapons. Benign sonic effects are certainly
familiar, ranging from the sonic boom from an airplane to the ultrasound
instrument that "sees" a baby in the uterus. The military is looking for
something less benign--an acoustic weapon with frequencies tunable all the
way up to lethal. Indeed, Huntington Beach-based Scientific Applications &
Research Associates Inc. (SARA) has built a device that will make internal
organs resonate: The effects can run from discomfort to damage or death. If
used to protect an area, its beams would make intruders increasingly
uncomfortable the closer they get. "We have built several prototypes," says
Parviz Parhami, SARA's CEO. Such acoustic fences, he says, could be deployed
today. He estimates that five to 10 years will be needed to develop acoustic
rifles and other more exotic weapons, but adds, "I have heard people as
optimistic as one to two years." The military also envisions acoustic fields
being used to control riots or to clear paths for convoys.
SARA's acoustic devices have
already been tested at the Camp Pendleton Marine Corps Base, near the
company's Huntington Beach office. And they were considered for Somalia. "We
asked for acoustics," says one nonlethal weapons expert who was there. But
the Department of Defense said, "No," since they were still untested. The
Pentagon feared they could have caused permanent injury to pregnant women,
the old, or the sick. Parhami sees acoustics "as just one more tool" for the
military and law enforcement. "Like any tool, I suppose this can be abused,"
he says. "But like any tool, it can be used in a humane and ethical way."
Toward the end of World War
II, the Germans were reported to have made a different type of acoustic
device. It looked like a large cannon and sent out a sonic boomlike shock
wave that in theory could have felled a B-17 bomber. In the mid-1940s, the
U.S. Navy created a program called Project Squid to study the German vortex
technology. The results are unknown. But Guy Obolensky, an American
inventor, says he replicated the Nazi device in his laboratory in 1949.
Against hard objects the effect was astounding, he says: It could snap a
board like a twig. Against soft targets like people, it had a different
effect. "I felt like I had been hit by a thick rubber blanket," says
Obolensky, who once stood in its path. The idea seemed to founder for years
until recently, when the military was intrigued by its nonlethal
possibilities. The Army and Navy now have vortex projects underway. The SARA
lab has tested its prototype device at Camp Pendleton, one source says.
The Soviets were known to
have potent blinding lasers. They were also feared to have developed
acoustic and radio-wave weapons. The 1987 issue of Soviet Military Power,
a cold war Pentagon publication, warned that the Soviets might be close to
"a prototype short-range tactical RF [radio frequency] weapon." The
Washington Post reported that year that the Soviets had used such
weapons to kill goats at 1 kilometer's range. The Pentagon, it turns out,
has been pursuing similar devices since the 1960s.
Typical of some of the more
exotic proposals are those from Clay Easterly. Last December, Easterly--who
works at the Health Sciences Research Division of Oak Ridge National
Laboratory--briefed the Marine Corps on work he had conducted for the
National Institute of Justice, which does research on crime control. One of
the projects he suggested was an electromagnetic gun that would "induce
epilepticlike seizures." Another was a "thermal gun [that] would have the
operational effect of heating the body to 105 to 107" degrees Fahrenheit.
Such effects would bring on discomfort, fevers, or even death.
But, unlike the work on
blinding lasers and acoustic weapons, progress here has been slow. The
biggest problem is power. High-powered microwaves intended to heat someone
standing 200 yards away to 105 degrees Fahrenheit may kill someone standing
10 yards away. On the other hand, electromagnetic fields weaken quickly with
distance from the source. And beams of such energy are difficult to direct
to their target. Mission Research Corp. of Albuquerque, N.M., has used a
computer model to study the ability of microwaves to stimulate the body's
peripheral nervous system. "If sufficient peripheral nerves fire, then the
body shuts down to further stimulus, producing the so-called stun effect,"
an abstract states. But, it concludes, "the ranges at which this can be done
are only a few meters."
laboratories and private contractors are pursuing numerous similar programs.
A 1996 Air Force Scientific Advisory Board report on future weapons, for
instance, includes a classified section on a radio frequency or "RF
Gunship." Other military documents confirm that radio-frequency
antipersonnel weapons programs are underway. And the Air Force's Armstrong
Laboratory at Brooks Air Force Base in Texas is heavily engaged in such
research. According to budget documents, the lab intends to spend more than
$110 million over the next six years "to exploit less-than-lethal biological
effects of electromagnetic radiation for Air Force security, peacekeeping,
and war-fighting operations."
From 1980 to 1983, a man
named Eldon Byrd ran the Marine Corps Nonlethal Electromagnetic Weapons
project. He conducted most of his research at the Armed Forces Radiobiology
Research Institute in Bethesda, Md. "We were looking at electrical activity
in the brain and how to influence it," he says. Byrd, a specialist in
medical engineering and bioeffects, funded small research projects,
including a paper on vortex weapons by Obolensky. He conducted experiments
on animals--and even on himself--to see if brain waves would move into sync
with waves impinging on them from the outside. (He found that they would,
but the effect was short lived.)
By using very low frequency
electromagnetic radiation--the waves way below radio frequencies on the
electromagnetic spectrum--he found he could induce the brain to release
behavior-regulating chemicals. "We could put animals into a stupor," he
says, by hitting them with these frequencies. "We got chick brains--in
vitro--to dump 80 percent of the natural opioids in their brains," Byrd
says. He even ran a small project that used magnetic fields to cause certain
brain cells in rats to release histamine. In humans, this would cause
instant flulike symptoms and produce nausea. "These fields were extremely
weak. They were undetectable," says Byrd. "The effects were nonlethal and
reversible. You could disable a person temporarily," Byrd hypothesizes. "It
[would have been] like a stun gun."
Byrd never tested any of his
hardware in the field, and his program, scheduled for four years, apparently
was closed down after two, he says. "The work was really outstanding," he
grumbles. "We would have had a weapon in one year." Byrd says he was told
his work would be unclassified, "unless it works." Because it worked, he
suspects that the program "went black." Other scientists tell similar tales
of research on electromagnetic radiation turning top secret once successful
results were achieved. There are clues that such work is continuing. In
1995, the annual meeting of four-star U.S. Air Force generals--called
CORONA--reviewed more than 1,000 potential projects. One was called "Put the
Enemy to Sleep/Keep the Enemy From Sleeping." It called for exploring
"acoustics," "microwaves," and "brain-wave manipulation" to alter sleep
patterns. It was one of only three projects approved for initial
As the military continues
its search for nonlethal weapons, one device that works on contact has
already hit the streets. It is called the "Pulse Wave Myotron." A sales
video shows it in action. A big, thuggish-looking "criminal" approaches a
well-dressed woman. As he tries to choke her, she touches him with a white
device about the size of a pack of cigarettes. He falls to the floor in a
fetal position, seemingly paralyzed but with eyes open, and he does not
recover for minutes.
"Contact with the Myotron,"
says the narrator, "feels like millions of tiny needles are sent racing
through the body. This is a result of scrambling the signals from the motor
cortex region of the brain," he says. "It is horrible," says William Gunby,
CEO of the company that developed the Myotron. "It is no toy." The Myotron
overrides voluntary--but not involuntary--muscle movements, so the victim's
vital functions are maintained. Sales are targeted at women, but law
enforcement officers and agencies--including the Arizona state police and
bailiffs with the New York Supreme Court--have purchased the device, Gunby
says. A special model built for law enforcement, called the Black Widow, is
being tested by the FBI, he says. "I hope they don't order a lot soon," he
adds. "The Russian government just ordered 100,000 of them, and I need to
replenish my stock."
The U.S. military also has
shown interest in the Myotron. "About the time of the gulf war, I got calls
from people in the military," recalls Gunby. "They asked me about bonding
the Myotron's pulse wave to a laser beam so that everyone in the path of the
laser would collapse." While it could not be done, Gunby says, he
nonetheless was warned to keep quiet. "I was told that these calls were
totally confidential," he says, "and that they would completely deny it if I
ever mentioned it."
Some say such secrecy is
necessary in new-weapons development. But others think it is a mistake.
"Because the programs are secret, the sponsorship is low level, and the
technology is unconventional," says William Arkin of Human Rights Watch Arms
Project, "the military has not done any of the things to determine if the
money is being well spent or the programs are a good idea." It should not be
long before the evidence is in.
