DARPA has managed to create a bullet, which can be fired by an expert or a novice, that moves in the air and steers itself to its target.

The agency’s Extreme Accuracy Tasked Ordnance (EXACTO) was created to increase the hit rates for long-range shots.

The latest round of testing, held in February, went better than officials were expecting with the programme manager, Jerome Dunn, going as far to say it “demonstrated what was once thought impossible”.
