DARPA's Extreme Accuracy Tasked Ordnance (EXACTO) program recently conducted the first successful live-fire tests demonstrating in-flight guidance of .50-caliber bullets.
This video shows EXACTO rounds maneuvering in flight to hit targets that are offset from where the sniper rifle is initially aimed. EXACTO's specially designed ammunition and real-time optical guidance system help track and direct projectiles to their targets by compensating for weather, wind, target movement and other factors that could impede successful aim.
