Accurate & Responsive Precision Mortar
The Precision Extended Range Munition (PERM) is a U.S. Marine Corps program that adds a precision mortar munition to the existing suite of 120 mm ballistic mortars fired from the mobile launching system (Expeditionary Fire Support System or EFSS). A precision mortar, sometimes called a "smart weapon," is a guided mortar designed to hit a specific target. The Raytheon PERM solution combines GPS guidance with a unique, aerodynamic design to improve accuracy. It has double the range of current ballistic mortars, while reducing delivery errors. Such range and precision is essential for reducing collateral damage, logistical requirements and target bracketing.
