Army delivers GPSguided mortars to soldiers in Afghanistan

first_imgWhen you think of a mortar most people think of a simple weapon soldiers drop into a tube that launches it when it hits the bottom. Once launched the accuracy of the mortar is dependent on the angle of the tube and the wind conditions, which is why a number of them are typically fired at once. In modern warfare, increased accuracy is key to ensure civilians aren’t injured, especially when fighting in urban environments. That’s why the U.S. Army has now giving soldiers in Afghanistan a new kind of mortar.The Accelerated Prevision Mortar Initiative, or APMI for short, takes a standard M934 high-explosive 120mm projectile body and places a GPS receiver and computer in the nose of it to allow control of the weapon’s directional fins ensuring it remains on its programmed trajectory. The APMI program has a high degree of accuracy, despite it’s short lifespan. In fact, it is required to fall within a circle with a 10 meters radius, 50% of the time, though Peter Burke, PEO Ammunition’s deputy product manager, says that the projectile is exceeding that requirement. Burke went on to say that the APMI is not replacing the standard 120mm mortars used today, but is instead designed to give a commander the ability to hit a target with a higher degree of accuracy in the event there is danger of accidental harm to civilians or non-military property.Besides improved accuracy, APMI also reduces the burden of resupplying soldiers with ammunition. Normally, 25 high-explosive rounds might be carried by a mortar unit to take out a target. That’s because their inherent inaccuracy typical requires volleys of fire in order to compromise a target. With the improved accuracy offered by APMI, it may take only one or two rounds to eliminate the same target.Read more at the U.S. Army, via Navigadget.last_img read more
