The U.S. Army Wants 'Bullets' That Can Chase a Tank or a Fighter Jet
The U.S. Army wants bullets and mortar shells that do more than hit a target. It wants projectiles that can hit a moving tank or even an aircraft in flight.
It's a worthy idea, except there is a problem. Building small projectiles with actuators—the mechanical parts and control surfaces that would adjust the projectile's trajectory—that can survive being shot out of a gun is a challenge.
