The U.S. Army is working on a new artillery shell capable of locating enemy targets, including moving tanks and armored vehicles. The shell, called Cannon-Delivered Area Effects Munition (C-DAEM), is designed to replace older weapons that leave behind unexploded cluster bomblets on the battlefield that might pose a threat to civilians. The shell is designed to hit targets even in situations where GPS is jammed and friendly forces are not entirely sure where the enemy is.
In the 1980s, the U.S. Army fielded dual purpose improved conventional munition (DPICM) artillery rounds. DPICM was basically the concept of cluster bombs applied to artillery, with a single shell packing dozens of tennis ball-sized grenades or bomblets. DPICM shells were designed to eject the bomblets over the battlefield, dispersing them over a wide area. The bomblets were useful unprotected infantry troops and could knock out a tank or armored vehicle's treads, weapons, or sensors, disabling it.
