A sniper fires on American troops in Iraq. In the milliseconds before the bullet hits - in fact, before the shot is even heard -- a computer screen reveals the gun's model and exact location. That's the kind of intelligence that can save soldiers' lives. The Army is currently testing the technology in combat.
The devices are made by Radiance Technologies, a small Alabama company, and differ in their approach to gunfire detection from systems already deployed in Iraq that rely on acoustics. Radiance's invention, WeaponWatch, is powered by infrared sensors that detect missiles or gunfire at the speed of light.
"Obviously when the first shot is fired, you can't do anything about it," said George Clark, president of the company founded in 1999. "But what it does do is it allows you to not have a second fired."
WeaponWatch is a major reason that Radiance, which had only three employees six years ago, now has 275. Over that period, it's been one of the 500 fastest-growing small businesses in the United States.
Nobody seems to dispute that WeaponWatch is the fastest such system on the market, but the challenge for company executives was persuading the Pentagon that those few extra nanoseconds provide any practical advantage over the existing sonar versions, which have a wider field of vision.
After all, human reflexes are far more sluggish than either light or sound.
Cambridge, Massachusetts, company BBN Technologies makes one of the leading acoustic devices. Its system detects enemy gunfire with an array of microphones and is known as Boomerang. Funded by the Defense Advanced Research Projects Agency, it was deployed in Iraq last year.
More than 100 of its units have been built, though the company is unsure how many are being used by soldiers.
Stephen Milligan, BBN's technology director, says a likely advantage of sonar is that it produces fewer false alarms than infrared.
"There are many ways to create an infrared flash," Milligan said. "I would guess it is ultimately possible to spook it."
But Charles Kimzey, who manages the Pentagon's research program that includes weapon detection systems, says that while both acoustic and infrared each have their advantages, early tests indicate Radiance's device is superior.
"The feedback we've gotten has been quite favorable," Kimzey said.
For security reasons, Pentagon officials refuse to disclose which U.S. military units have used WeaponWatch and where.
Walt Smith, a technology director at Radiance who traveled with the system to Iraq during its March 2004 launch, said soldiers like it because of its precision.
"A person who has a rugged tablet personal computer can see an image," Smith said. "Someone on the second floor, third window from the right, shot from that location."
The system was tested on top of a building where there was a high concentration of insurgent gunfire. Within a few days, American troops were able to use WeaponWatch to return fire more rapidly, Smith said, resulting in a noticeable drop in enemy attacks.
And that was the old 400-pound version -- clunky, cumbersome and highly susceptible to damage from high temperatures and the sand kicked up by desert winds. The newest version is less than 30 pounds and about the size of a lunch box. It can be stationary or placed on Humvees, tanks, helicopters and unmanned aerial vehicles.
"It has limitations like all technology," Smith said. "There's no perfect, silver bullet. But it's very effective in certain circumstances in an urban environment. In a desert environment it can be extremely effective."
WeaponWatch picks up on the infrared signature of every weapon the moment it is fired, instantly identifying it from a database of thousands of weapons muzzle flashes.
Kimzey said that because the technology has become so mobile and keeps getting smaller, there's virtually no end to the possibilities. For example, the Marines recently tested a program that links the infrared detector to an automatic weapon. It would allow the combatant wielding that weapon to get a shot off almost immediately after the enemy fired.
Kimzey said such an invention could be problematic because military rules of engagement require that a human being, and not a machine make firing decisions in the field of combat.
The federal government has invested nearly $15 million over five years in developing the infrared technology. Besides the four test models being used in Iraq, another 20 have been ordered.
Kimzey said it's unclear how much the Pentagon will spend on the program when it moves from research to deployment, but he said it's definitely an investment the Defense Department plans to make.
"As the sensor develops its capability and becomes convincing, folks are knowing about it and they're asking for it," Kimzey said.
