Guided Bullets

If the system works, it'll "provide a dramatic new capability to the U.S. military," Darpa says. "The use of an actively controlled bullet will make it possible to counter environmental effects such as crosswinds and air density, and prosecute both stationary and moving targets while enhancing shooter covertness. This capability would have the further benefit of providing increased accuracy and range while reducing training requirements."

"In other words," Sharon wrote last year, "it would be the ultimate sniper round."

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 the will say that EXACTO should contain 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."
