 Though the Javelin's tandem HEAT warhead has proven efficient at destroying tanks, most threats it was employed against in Iraq and Afghanistan were weapon crews and teams, buildings, and lightly armored and unarmored vehicles.To make the Javelin more useful in these scenarios, the Aviation and Missile Research, Development, and Engineering Center developed a multi-purpose warhead (MPWH) for the FGM-148F.While it is still lethal against tanks, the new warhead has a naturally fragmenting steel warhead case that doubles the effectiveness against personnel due to enhanced fragmentation.
