The key objectives of theprogram are to reduce the weight of weapons carried by infantrymen by 35% and lessen the weight of ammunition by 40% while maintaining or improving lethality and reliability over current weapons.
XM25 Individual Airburst Weapon System is currently under development and intended to address the capability gap of defeating defilade targets. The weapon has the capability to hit point targets at a distance of 546 yards (500 meters) and area targets at 765 yards (700 meters). 25mm munitions currently in development include High Explosive Air-Burst (HEAB), armor piercing, door breaching, anti-personnel, and two types of non-lethal munitions – blunt and agent dispersing airburst.
