The US military is testing an 'intelligent' bullet (do you have any doubts about the previous definitions of intelligence in relation to weapons? Me too) within a research program called EXACTO (EXtreme Accuracy Tasked Ordinance): in these tests ( started in February 2015 and disclosed two weeks ago) all participants were able to hit a moving target with absolute precision.
The bullet benefits from a real-time laser guidance system that follows the target and corrects the trajectory if necessary, verifying the position 30 times per second. The result? Objective hit in all cases. No escape. Here is a small scheme of operation:
“This test clearly demonstrates how Exacto is capable of hitting moving and fleeing targets with incredible accuracy and in a range never reached by traditional weapons. Being able to pack the Exacto guidance system into a small .50 caliber is a revolutionary achievement, and paves the way for guided projectiles for every caliber, ”he says.
