Laser gunship hits $30 million bulls-eye

Tuesday, Oct 21, 2008

The U.S. Air Force has awarded Boeing a new contract worth up to $30 million for the next phase of development on the Advanced Tactical Laser.

The ATL is a C-130H aircraft outfitted with a 12,000-pound high-energy chemical laser module that would be used as a weapon against ground targets. Its the smaller sibling of the Airborne Laser, a highly modified 747 under development that packs a similar weapon but that would be used against ballistic missiles.

The Advanced Tactical Laser will use a rotating ball turret to fire its laser weapon at ground targets.

While the 747-centric ABL is designed to fire its laser through a bulbous nose apparatus, the ATL totes a belly turret reminiscent of the manned versions used in some World War II bombers.

The new Extended User Evaluation contract marks the start of a transition for the ATL, which Boeing has been working on as an Advanced Concept Technology Demonstration project. The EUE phase means another round of ground and flight tests, along with hands-on operation for the Air Force and other potential users.

Why use a laser when the Air Force already has a wide array of missiles and bombs at its disposal? (The standard gunship variant of the C-130 can already be equipped with 40mm and 105mm cannons.) Little to no collateral damage, Boeing says, thanks to the laser weapons ultra-precision engagement capability. That is, think laser pointer with extreme prejudice.

In addition, the laser would presumably strike more or less silently no thump-thump-thump or rat-a-tat-tat.

For use against missiles, mortars, and the like, laser weapons are intended to heat up and weaken the metal skin of the projectile, causing it to rupture while in flight. Against ground targets, the ATL could, say, zap fuel tanks or even vehicle tires if it could hold focus long enough.

In a Medill Reports story on the ATL, Northwestern University engineering professor Manijeh Razeghi said there is a range of potential military uses for lasers.

Lasers can create fires. They can kill, said Ragezhi, who has worked on lasers for the military. Each (laser) wavelength has some application. Some of them you know about; some of them are classified, and we cannot speak about them.

The National Academies of Science, meanwhile, is raising questions about the overall costs of laser weapons programs, the power requirements for the systems, and just how much collateral damage might actually occur, according to Wired's Danger Room blog.
