Airborne lasers. Electromagnetic Barriers. Bom Bots. They sound
like weapons used against the Rebel Alliance in Star Wars. Yet,
there’s no science fiction here. All are current Air Force
Research Laboratory technologies, some of which already have been
deployed to Iraq.
AFRL
developed and delivered what it calls Bom Bots. These are small,
remotely controlled robots that disable and dispose of roadside
bombs and improvised explosive devices used by insurgents in Iraq
against U.S. troops.
“The war fighters love them,” says Les McFawn, executive
director of AFRL. “They have asked for more of these because,
obviously, it keeps them out of harm’s way.”
The technologies available to detect IEDs, however, need to be
improved, McFawn tells National Defense. “There is an issue
with finding IEDs. If you found one, the Bom Bot is great, but clearly
there are a lot of these IEDs that we’re not finding. So we
need some techniques for either finding them or disrupting their
placement.”
Another AFRL effort got under way in June, when the lab awarded
a $1.5 million contract to Alliant Techsystems to develop high-power
microwave technologies that will be capable of disabling a variety
of IEDs, says Juvenito R. Garcia, a spokesman for AFRL directed
energy directorate, at Kirkland Air Force Base, N.M.
AFRL and Alliant, under a previous agreement, had developed a prototype
system, called Scorpion I. In tests at Yuma Proving Ground, Ariz.,
the Scorpion I neutralized approximately 74 percent of the IEDs
it encountered. “We are proud of that achievement and are
confident that we will continue to mature the technology with the
goal of developing a fieldable and deployable system as rapidly
as possible,” said Alliant spokesman Bryce Hallowell.
Under the most recent contract, AFRL and Alliant will adapt the
Scorpion I design to develop a portable device called Scorpion II,
which will find and disarm IEDs.
These projects are only small pieces of a broader Defense Department
effort to develop and field anti-IED technologies.
An organization dubbed the Joint IED Defeat Task Force is charged
with coordinating all Defense Department projects aimed at countering
IEDs. While the services sometimes pursue their own efforts, the
task force often coordinates and tries to consolidate redundant
development and production programs. In fiscal year 2005, the task
force spent $1.4 billion on new technologies.
In March, the task force issued a solicitation for industry bids,
under a “broad agency announcement.” From more than
800 responses, 32 were selected for additional evaluation. White
papers with varying degrees of information were requested for each
of the 32. “The review of those white papers is underway now,
and we expect to see initial contracts awarded this fall,”
according to Christine Devries, a spokeswoman for the IED Task Force.
“We have been successful at deploying technology and equipment
within weeks and months, rather than months and years,” she
says in written responses to questions from National Defense. “We
realize that we already have plucked the low-hanging fruit. The
next-generation technology requires development to meet specific
needs,” she adds. “Therefore, we also are prepared to
pursue and fund promising innovations that might have a longer lead-time
before showing return.”
Syracuse Research Corp. recently won a $550 million contract from
the Army to develop a counter-IED system, known as CREW Spiral 2
(Counter Remote Control Improvised Explosive Device Electronic Warfare
System).
The CREW Spiral 2 devices will be installed on Army vehicles and
will perform in similar ways to the Scorpion II. Work on this project
is estimated to be completed by 2010.
McFawn describes the process of developing and improving anti-IED
technologies as “boot strapping.” Troops take technologies
and weapons systems, and develop tactics, procedures, concepts of
operation, he explains, and “invariably they figure out better
ways to use them than we had originally envisioned. They learn how
to employ them and they feed back their experiences.”
A major challenge in countering IEDs is access to timely intelligence
about the enemy’s intent, says McFawn. “To what extent
can we anticipate and influence the actions of the enemy?”
Also, researchers at AFRL must try to predict how the enemy will
rework commercial technologies to improve the effectiveness of IEDs.
“Commercial technology is highly capable and can be adapted
for military use by groups like the terrorists, and we need to be
able to proactively adapt and rapidly develop technologies in response.
The whole issue of speed is key,” says McFawn.
Scientists at AFRL, meanwhile, also are focusing on technologies
that the military will need in 10 to 20 years. One example of such
research is in the field of nano-science, particularly with highly
energetic materials. AFRL envisions doubling the propulsive power
for missiles and rockets, or basically creating high-energy explosives
that, pound for pound, are 10 to 50 times greater than the ones
used today, McFawn says.
Other long-term projects include the development of speed-of-light
weaponry, large thin-film optics, electromagnetic protection and
airborne lasers. Speed-of-light weapons will be smaller, lighter
and more powerful than conventional systems, Garcia says. Large
thin-film optics, or mirrors the size of football fields, could
be used in space to direct energy from one site to another.
Directed energy can be applied in defensive systems, McFawn adds.
“You can envision a directed-energy system that basically
provides a total barrier around an air base or around an aircraft
… That concept of being able to have a sphere of electromagnetic
protection—be it high-power microwave or high-power laser—to
protect yourself, is a pretty powerful concept.”
In the near future, research will be pushed towards developing
the airborne laser, a megawatt-class device mounted aboard a Boeing
747-400 freighter to destroy ballistic missiles shortly after launch.
