Shipers says the technology has already cleared a hurdle that experts had said couldn’t be overcome: the survival of the battery and chip, despite their being fired out of a .50-caliber rifle. Launch tests found that the munition’s innards did indeed stand up to the crushing 120 000 g-force acceleration and 344.7 megapascals (50 000 pounds per square inch) of pressure as the bullet comes hurtling out of the barrel. The next step is to find a commercial partner that can turn the ideas now being bench-tested into a field-ready bullet. This "smart bullet" actually improves its accuracy with distance, and is capable of hitting a target a mile away within 8 inches.
