[2] In mid-2016, Russia revealed it was developing a similar "smart bullet" weapon designed to hit targets at a distance of up to 10 kilometres (6.2 mi).
As the bullet approaches its final destination, it adjusts its flight path in real time to allow an equivalent amount of light from the laser to enter each eye.
The bullet would not travel in multiple directions as though it were an autonomous vehicle, but instead, would make small adjustments to its flight path to hit the target precisely where the laser was placed.
[6] Barrett went to great lengths to model the airflow of the bullet, studying butterflies with speed bumps to evaluate the effects of protruding surfaces.
[8] Honeywell Aerospace has produced inertial measurement units based on MEMS and microelectronics technologies that it claims can survive the shock of being fired out of a gun.
