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 provides double the effectiveness against personnel due to enhanced fragmentation. The MPWH does not add weight or cost and has a lighter composite missile mid-body to enable drop-in replacement to current Javelin tubes.
