The U.S. government has developed the first ever self-guided bullet.

The .50 caliber target tracking bullets, dubbed Extreme Accuracy Tasked Ordnance (EXACTO), can lock onto a target more than a mile away and maneuver midflight in order to hit its mark. Teledyne Scientific and Imaging is developing the bullet.

The system combines the maneuverable bullet with a real-time laser-guidance system to track and deliver the projectile to the target.



DARPA said on its website: “For military snipers, acquiring moving targets in unfavorable conditions, such as high winds and dusty terrain commonly found in Afghanistan, is extremely challenging with current technology. It is critical that snipers be able to engage targets faster, and with better accuracy, since any shot that doesn’t hit a target also risks the safety of troops by indicating their presence and potentially exposing their location.”
