Four inch laser guided bullet ranges up to 2000 meters - image

Sandia National Laboratories engineers have developed a design for a laser-guided bullet. The 4″-long laser-guided projectile has made hits at ranges up to 2000 meters.

The projectile shoots from a smooth-bore rifle and uses small, movable fins to adjust its trajectory. The fins are controlled by micro-sized actuators in response to signals from a tiny, onboard laser-sensor. Plastic sabots provide a gas seal and protect the delicate fins while the projectile is in the firearmís barrel.

The self-guided bullet homes in on a laser spot trained on a target from up to 1.4 kilometres away from its firing point. If the target is a moving truck, say, and it moves after the bullet is fired, the laser illumination as seen by a laser sensor in the bullet's nose instructs the bullet to finely twist tiny rudder-like fins on its rear end to keep it on target.
