Self-steering bullet researched by US weapons experts
A self-guiding bullet that can steer itself towards its target is being developed for use by the US military.
The bullet uses tiny fins to correct the course of its flight allowing it to hit laser-illuminated targets.
It is designed to be capable of hitting objects at distances of about 2km (1.24 miles). Work on a prototype suggests that accuracy is best at longer ranges.
