DARPA's Extreme Accuracy Tasked Ordnance (EXACTO) program, which developed a self-steering bullet to increase hit rates for difficult long-distance shots, completed in February its most successful round of live-fire tests to date. An experienced shooter using the system repeatedly hit moving and evading targets. A novice shooter using the system for the first time also hit a moving target. This video shows EXACTO rounds maneuvering in flight to hit targets that are moving and accelerating. 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 can impede successful hits.
