The Pentagon is tossing $22 million at developing guided bullet technology that would enable a bullet to change course midflight because it wasn't shot right first in the first place, the wind changed, or the head you were aiming at moved. *closing blinds* Greeeaaaaat.Darpa won't say, publicly, how far, how long and how accurate they want the new bullets to be -- all that information is classified. But they will say that Exacto should contain a next-gen scope, a guidance system that provides information to direct the projectile, an "actively controlled .50-caliber projectile that uses this information for real-time directional flight control," and a rifle. "Technologies of interest may include: fin-stabilized projectiles, spin-stabilized projectiles, internal and/or external aero-actuation control methods, projectile guidance technologies, tamper proofing, small stable power supplies, and advanced sighting, optical resolution and clarity technologies."
