increasing accuracy over the conventional M934A1 High Explosive (HE) cartridge by approximately seven times at maxi- mum range.
LTC David Womack, Commander of 1st Battalion, 506th Infantry Regiment, the first unit equipped, said, “The 120mm precision guided munitions will allow Task Force Red Currahee to provide even more effective fires with increased lethal- ity. The accuracy of the [cartridge] also reduces the potential risk of any collateral damage. As a commander, I have another tool available to fight the enemy.”
The XM395 APMI is the world’s first GPS guided mortar cartridge. With the field- ing of APMI, maneuver battalions within U.S. Forces-Afghanistan infantry brigade combat teams (IBCTs) have a precision organic indirect-fire capability providing lethal first-round effects on target to sup- port combat operations in OEF. Unlike the conventional mortar round, which has no guidance after gun launch, the 120mm APMI uses the GPS to correct its flight and can hit a target location within
10 meters or less. This helps mitigate col- lateral damage and offers greater accuracy, and first round fire-for-effect helps reduce the number of rounds required to success- fully defeat high-value targets.
XM395 DESIGN The XM395 cartridge is composed of three subassemblies: nose, body, and tail (see Figure 1).
The nose subsystem contains a “smart” fuze that contains the GPS guidance sys- tem and a controllable canard system that uses small fins to steer the cartridge to its preprogrammed target location. A remov- able protective canard cover facilitates the loading of data to the fuze subsystem.
The body is the standard M934A1, modified to accept the smart fuze and con- taining the same Composition B HE fill.
The tail subsystem uses the standard 120mm ignition cartridge and four removable propellant charges. Modifica- tions include four longer, deployable fins to increase stability.
