The key objectives of the LSAT program 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. At AUSA 2006 the XM116
sight was displayed by L3 (Formerly Brashear). Two additional
types of support weapons currently under development are the
XM-307 25mm Advanced Crew Served Weapon which will use the
same 25mm ammunition as the XM25. It will also have a lightweight
machine gun derivative designated XM-312 firing standard and
enhanced 0.50 Caliber (12.7mm) ammunition.
