Smart Bullets


Have arrived:

The U.S. military has been after self-guided bullets for years. Now, government researchers have finally made it happen: a bullet that can navigate itself a full mile before successfully nailing its target. … Even with an ace marksman, researchers found that a typical unguided bullet — operating in real world conditions that might include crosswinds or changes in air density — would miss a target that was a half-mile away by nine meters. A guided bullet, however, could get within eight inches of that same target.
