digg_url = 'http://digg.com/gadgets/How_It_Works_The_Airborne_Laser_Cannon'; Creating a laser that can melt a soda can in a lab is a finicky enough task. Later this year, scientists will put a 40,000-pound chemical laser in the belly of a gunship flying at 300 mph and take aim at targets as far away as five miles. And were not talking aluminum cans. Boeings new Advanced Tactical Laser will cook trucks, tanks, radio stations—the kinds of things hit with missiles and rockets today. Whereas conventional projectiles can lose sight of their target and be shot down or deflected, the ATL moves at the speed of light and can strike several targets in rapid succession.
Using a laser on the battlefield may be a good thing. Mounting it in a slow flying unarmed aircraft sounds like a really bad idea. In fact, after the US has spent billions to develop the technology we can look forward to our next opponent stealing the technology and mounting it inside a steel shipping container (conex box) and using it as a fairly effective antiaircraft weapon (especially against slow low flying C-130's trying to locate and destroy ground targets with their lasers). After they've shot down a few planes with the shipping container AA system, they can just start moving empty shipping containers into an area to scare away attacking planes. Keep working on the laser, but re-think that platform idea.
