On Thursday, the Defense Advanced Research Projects Agency (DARPA) successfully tested the world’s first small-caliber, self-guided bullet against a moving target 6,500 feet away.
The featured video shows an Extreme Accuracy Tasked Ordinance (EXACTO) .50-caliber bullet readjust its trajectory mid-flight to successfully strike a target that was purposefully moved.
Developed by Sandia National Laboratories and Lockheed Martin, this specialized bullet is 4-inches long and has an optical tip that detects and follows laser beams directed at targets. Inside, the bullet has actuators (small motors) that move tiny fins located along the surface of the bullet. These fins help redirect the bullet based on the information collected from the optical sensor at the tip that constantly assesses the position of the laser-designated target.

According to the program page, “The system combines a maneuverable bullet and a real-time guidance system to track and deliver the projectile to the target, allowing the bullet to change path during flight to compensate for any unexpected factors that may drive it off course.”
