U.S. Army developing smart munitions for future weapons like rail gun that can chase a Tank or a Fighter Jet

Gun-launched guided munitions are of tremendous interest to the U.S. Army. These technologies offer more accuracy, extended range through glide, more favorable terminal approach for lethality, and the ability to engage advanced threats like partially hidden (defilade) and moving ground and air targets. Current gun-launched guided munition technologies are limited to indirect fire against stationary targets on the ground.

Research conducted 10+ years ago was pivotal in providing capabilities of guided shells which could adjust its trajectory in flight to the U.S. Army. The M982 (Excalibur), fielded in the mid-2000s, is a guided artillery projectile which delivers the warhead to within about 10m of the target compared with traditional unguided artillery which have a delivery accuracy of about 200m.
