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 500 meters and area targets at 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
XM25 will be able to set the fuse of each round to explode
over the target, to create maximum effect. After placing the
aimpoint on the target and activating the laser rangefinder,
the system calculates the range to the target, and converts
it to time of flight for fuse setting. XM25 will utilize the
XM116 integral fire control system, which will include day and
night channels, laser rangefinder, fuse setter, compass, ballistic
computer and an internal display. At AUSA 2006 the XM116 sight
was displayed by L3 (Formerly Brashear).
A predecessor of the XM-25 was the
XM29 Objective Individual Combat Weapon (OICW), which was developed
as a future replacement to both t M16/M4 and M203 individual
weapon system. The program was cancelled, as the U.S. Army favored
a more capable 25mm ammunition, which required the use of a
separate weapon rifle and grenade launcher.
