“Our .50-caliber bullet can guide itself to a hit half a mile away”

For years, people have tried to come up with ways to steer bullets, and everyone has consistently said you can’t do it. And you couldn’t—if the bullet was spinning. A spinning bullet is too stable; you can’t apply enough force to turn it off its axis of revolution. The secret sauce is that our bullet doesn’t spin. It’s kind of like a musket ball, which doesn’t rotate, but with technology added to let us control where it goes.
Precision guided weapons are usually the purview of larger weapons platforms, like naval vessels, combat aircraft, or assault vehicles. But a couple of Sandia National Labs engineers are bringing the guided munition down from the mountaintop and putting it into the hands of the average infantryman. The engineers have developed and patented a new breed of self-guided bullet that can navigate its way to a laser-designated target at ranges of more than a mile.
