Urgent Search for Speed

WESTMINSTER,
Md. -- In soldier slang, the interval between a gun's recoil and the shell's
explosion is known as "flash-to-bang time." In combat, the shorter
it is, the better.
With war
looming in Iraq, the term has taken on broader significance in
both the business of war and the business of supplying warriors. Everyone
wants shorter flash-to-bang from the moment a target is spotted
to the moment it is destroyed, from the moment a march is ordered to the
moment troops arrive, from the moment of invention to the moment of production
and delivery.
That is why, here in the rural hills of Maryland, at a robotics laboratory
owned by General Dynamics, the engineers boast that their new driverless
vehicles, little armored off-road trucks bulging with lenses and antennae,
can maneuver through the woods and fields at a snappy 15 or 20 miles an
hour (10 at night).
And that
is why General Dynamics, after just two years working on the vehicles,
is ready to brief the brass on how robotic vehicles like this could transform
combat units. The company says the firepower of a full infantry battalion
could be packed into a unit of about one-third the people: 270 soldiers
equipped with 140 robots.
The same
quick tempo can be seen across the military industrial complex. Faster-moving
infantry, smarter bombs, newer satellites, pilotless vehicles are
all being propelled by a wartime sense of urgency in what is sure to be
a costly quest for speed. The average time between finding a target and
hitting it dropped to 15 minutes in Afghanistan a year ago from 45 minutes
in the Persian Gulf war of 1991. And the Pentagon is pushing to trim that
even more.
At Boeing,
thousands of kits are being produced each month to turn unguided bombs
into the satellite-guided smart bombs that were used more widely in Afghanistan
than in any previous war. Pentagon leaders have promised that if there
is war in Iraq, there will be plenty of smart bombs.
Before a
satellite can guide a bomb to target, the satellite must carry target
information among soldiers, pilots and commanders. With today's satellites
swamped by a growing demand, manufacturers like Boeing and Lockheed Martin
are eagerly awaiting the order to move ahead with a next-generation satellite,
using lasers for the first time to communicate in outer space.
The lessons
of Afghanistan, as well as the pressing possibility of war against Iraq,
are speeding production of remote-controlled aircraft like the Predator,
which the military uses to track targets and the C.I.A. has used to kill
people identified as Al Qaeda leaders in Afghanistan and Yemen. This year,
Congress is allowing $131 million to buy 22 more Predators, made by General
Atomics Aeronautical Systems. And $129 million more is to be spent on
three of the Predator's much larger, more capable and more expensive cousin,
the Global Hawk surveillance drone, made by Northrop Grumman. Global Hawk
was rushed into service in Afghanistan, and its capabilities are still
being upgraded with new sensors. (The price of a souped-up model would
be about twice as much.)
"Speed
is helpful if you know what you're looking at and can identify in near
real time what your targets are," said Stephen A. Cambone, the under
secretary of defense for policy, in a recent briefing on the military's
spending priorities. "You say, `Gee, if I can get that kind of real-time
information, speed then is worth having.' " But, he stressed, "speed's
expensive."
With American
troops still engaged in Afghanistan and getting ready for a possible war
against Iraq, and with the Bush administration promising a "transformation"
of the military, Congress appears willing to pay the price. In recent
years, it has increased the military's budget beyond what the president
requested, and military spending is now growing at its highest rate in
20 years. With Republicans controlling both chambers, President Bush is
sure to get a warm reception for another spending increase in 2004.
David Strauss,
who follows the military industry for UBS Warburg, predicts that spending
on research, development and procurement will accelerate to 8 or 10 percent
annually over the next few years, adjusted for inflation, after real growth
of 4 percent annually since 1996. (In the early 1990's, he says, the Pentagon
went on a "procurement holiday.")
Of the total
military budget of about $370 billion, procurement this year will come
to about $71.6 billion, up $10.7 billion from 2002, while spending on
research and development will come to $58.6 billion, up $9.9 billion,
in the spending bill signed by President Bush on Oct. 23. It sounds like
a lot, but in fact the money for procurement is roughly 40 percent less
than it was 20 years ago, adjusted for inflation. In 1983, during the
Reagan military buildup, procurement spending came to $121 billion in
today's dollars.
More notable
than the spending spree itself, though, is where the money is being focused.
President
Bush made the new emphasis clear last December, when he gave a major speech
on military transformation. He highlighted three trends that were already
becoming evident in the war in Afghanistan: the increasing use of robotic
vehicles, the wider use of precisely guided bombs and the reliance on
information-sharing networks.
"Our
commanders are gaining a real-time picture of the entire battlefield and
are able to get targeting information from sensor to shooter almost immediately,"
he said.
"Every
soldier is a sensor," said Scott D. Myers, the president of the robotic
systems division at General Dynamics and vice president of its Eagle Enterprises
subsidiary, which is bidding on the modernization of equipment for foot
soldiers. "And from the time he lases the target until the time the
robotic vehicle selects its weapon and fires will be about five seconds."
The Army
has been moving in this direction for years.
Late one
night in September 2000, 45 paratroopers of the 82nd Airborne Division
dropped from the dark skies over Fort Polk, La., for a mock combat drill
against other Army troops. They wore an unconventional assortment of night-vision
goggles, miniature computers and communications gear, a prototype of what
the Army calls its Land Warrior system. The equipment had been cobbled
together in just a year, and this was its first test.
The results
were good enough that only a year later, similar equipment was delivered
to American Special Forces units, which used it in Afghanistan.
It might
cost billions of dollars to equip tens of thousands of soldiers with the
full array of this gear, according to a report by the Pentagon's inspector
general. But the Army is phasing it in even as it begins a program
to invent an even more elaborate set of tools for foot soldiers.
The competition
to design the new combat kit pits General Dynamics, a giant with $14 billion
in annual revenue, against a tiny entrepreneurial company, Exponent Inc.,
which has not been a traditional military contractor. Exponent has enlisted
several partners, including Hamilton Sunstrand, a unit of United Technologies,
whose expertise in making spacesuits for NASA is a big advantage. Conversely,
General Dynamics has turned to its Eagle Enterprise unit, acquired a few
years ago, to be the kind of entrepreneur the Army is looking for. Each
team has been given $7.5 million to produce conceptual designs and some
prototypes, with an April deadline.
The ultimate
goal is to reduce the amount of equipment carried by an individual soldier
to roughly 50 pounds from more than 100, while greatly increasing the
lethality of his weapons. Pentagon budget documents call the program "a
leap ahead" and promise that it will achieve "revolutionary
capabilities." The Army has projected spending of about $60 million
a year for the next several years on research into the program and has
projected that the new equipment will be ready for combat use in a half-dozen
years or so.
Each soldier
will have hand-held computers to control weapons, check maps and view
pictures of the surrounding terrain. Individual radios will link the group
into a tight team even as they spread out in the darkness; each team will
be linked to others and to robots. In a squad of soldiers, one might carry
a miniature drone aircraft capable, for instance, of flying around a city
block to look for the enemy.
Even combat
fatigues will be transformed. Synthetic undergarments will put sensors
on the soldier's skin to monitor his physical condition, reporting if
he needs medical attention. Several layers of lightweight clothing would
include body armor and protection against chemical or biological attack.
With a vest
or other garment designed like an electric blanket, a soldier might even
be able to run a cord back to one of the robotic vehicles, which would
provide a power supply for the many electronic devices each soldier would
carry. (New batteries, carried by each soldier, are also being investigated;
designed to last for many hours, they would be recharged by the robotic
vehicles.)
But there
are many kinks in any such futuristic scheme. Congressional committees,
while supporting the Pentagon's development of hybrid-electric power for
vehicles like the robots the Army wants, have asked for periodic progress
reports, citing worries that they might not function well in extreme cold.
That would be a problem, for example, for a unit deployed in the mountains
of the Hindu Kush in Afghanistan in the dead of winter, unable to recharge
communications batteries or warm up soldiers' uniforms.
All the
emphasis on seamless communications among troops, ships and planes, and
the visions of individual soldiers sending maps and photographs back and
forth, or robots sending home streams of videos, have a glaring weakness:
there is not enough telecommunications capacity, or bandwidth, on the
military's satellites.
"You
need a lot of bandwidth to move that kind of data around," said Mr.
Cambone at the Pentagon. "Think about whether you would have been
able to use your 286 computer to work the Internet as it exists today.
You can't do it."
According
to Boeing, one satellite maker, that became clear when American forces
in Afghanistan found themselves short of enough radio channels even for
their more limited tactical communications. To fill the gap, the Navy
activated a nine-year-old satellite that had been put in orbit over Africa
as a spare. The old satellite added 15 percent more communications capability
to the military forces in the region.
The problem
has been known for some time. After the military's deployment in Bosnia,
the Defense Advanced Research Projects Agency reported that only a few
select headquarters were able to get enough bandwidth for large-scale
exchanges of information.
"One
thing we've learned," said Lt. Gen. Harry D. Raduege Jr., the director
of the Defense Information Systems Agency, "is that with each conflict
that we have, we certainly increase the amount of bandwidth that is required
for our deployed war fighters."
The need
for a new satellite system to carry videoconferences between commanders,
let alone the huge amounts of data shared by troops on the ground, became
especially evident after Sept. 11, according to a Pentagon document. In
response, the Pentagon has proposed a crash program to design and field
a new satellite system, known as the Advanced Wideband System, starting
this year and with the first launching in 2006.
Unlike previous
satellite communications systems, this one would use a new kind of link
entirely: one based on laser communications. As a mark of its importance
to the technology revolution the Pentagon is seeking, it is being called
by a new name: the transformational satellite.
Nobody can
say yet how much this will cost. But for a sense of the project's scale,
a set of satellites viewed as a temporary solution and known as the Wideband
Gapfiller Satellite is being built for $1.3 billion by a team led by Boeing.
In a change from past practices, the satellite relies heavily on commercial
technology, which will make it available earlier but will leave it more
vulnerable to certain kinds of attack, like the electromagnetic pulse
of a nuclear explosion in space.
Another
upgrade of satellites using extremely high frequency, or EHF, signals,
known as the Advanced EHF Satellite and set for launching in 2006, is
being built by Lockheed Martin Space Systems and TRW Space and Electronics
for $2.7 billion.
Air Force
officials have said that if the laser technology comes along fast enough,
they may decide not to buy the fourth and fifth Advanced EHF satellites,
instead moving quickly to the laser-based version. But they will not be
ready for that decision until the end of 2004. "Depends a little
bit on how much risk has been reduced by that point," said Peter
B. Teets, the Air Force under secretary.
MILITARY
analysts have already wondered whether all this communications capability
is too expensive. Marco A. Caceres, an analyst at the Teal Group, an aerospace
research firm, warned at an industry conference in January that some satellite
systems are already behind schedule, and that there will be pressure on
the military to lease capacity from commercial satellites rather than
building its own so hastily.
Others,
like Loren B. Thompson of the independent Lexington Institute, caution
that the Pentagon may commit too much, too soon to technologies that may
be overrated on the basis of unusual recent wars notably the victory
over the poorly trained and under-equipped Taliban forces in Afghanistan.
"The
incompetence of our adversaries has given us an exaggerated idea of how
much progress we have made in transforming our forces," he said.
