Developed as an extended range projectile program with increased accuracy to minimize collateral damage, the XM-982 has surpassed an amazing list of design requirements. It has been fielded in Iraq and Afghanistan since 2007. It has achieved ranges up to 40km, with an accuracy average CEP (Circular Error Probability demonstrated to be about 5 meters (16.5 feet) even when it was fired 5 degrees off course on purpose. The XM-982 is intended to become a family of carrier projectiles for submunitions and a unitary HE warhead. It uses GPS and inertial navigation to counter GPS jamming. A number of videos are hyperlinked below, along with some photos of the projectile and U.S. soldiers programming one before firing in Afghanistan.
