The AICW (Advanced Infantry Combat Weapon) is a joint development of the Australian DSTO (Government operated Defense Science and Technology Organization), and private companies Metal Storm and Tenix Defense. This development has been carried out since the turn of 21st century, closely following the concept of the American XM29 OICW system.
Overall, AICW represents the modular weapon system that combines the 5.56mm rifle/carbine component as a host (basic) platform with 40mm multi-shot grenade launcher (G/L) module and multi-purpose electro-optical sighting system, which can be used to fire either rifle or G/L component, and also can provide recon data to external “consumers” such as tactical computers.
The host rifle component of the AICW is the updated Australian-made F88 rifle, which is a license-built Steyr AUG. However, the basic F88 rifle has been extensively modified to accept other elements of the system – for example, the receiver has been upgraded to receive the G/L module at the top, and the butt stock has been enlarged to accommodate G/L electronic fire control module. Other changes include modification to the safety and trigger arrangements – AICW system has a single trigger for both weapon components (5.56 and 40mm) and a three position (safe – rifle – G/L) safety/selector switch at the side of the pistol grip.
The most interesting part of the AICW weapon is the multi-shot Metal Storm 40mm grenade launcher, which looks like a single 40mm G/L barrel but contains three 40mm projectiles stacked one behind the another. These projectiles are launched using the electric ignition impulses, provided by the fire control module built into the buttstock of the host rifle. Since the muzzle velocity of these projectiles is slightly more than usual for 40mm handheld G/L (95m/s instead of 75m/s), host rifle incorporates the recoil reduction buffer, that allows the Metal Storm G/L barrel to recoil against the spring, decreasing the peak recoil impulse.
The top of the receiver hosts the multi-role sights of various type and make. At the AICW VX3 live fire demonstrations that took place in the summer of 2005, AICW prototypes were displayed with ITL Viper multi-purpose rifle sight (that incorporates laser range-finder and digital compass), or with Vinghog Vingsight Fire Control System.
In late 2005 AICW prototypes have not yet fired 40mm grenades with live warheads, nor incorporated an airburst facility. However, it is stated that it is possible to easily adapt most of the existing 40mm grenade warheads to the Metal Storm technology, including air-bursting grenades that are now in development in several countries.
At the present time AICW weapons are available only as the “3rd generation technology demonstrators”, that completed first live-fire trials (as a complete system) in the summer of 2005. Australian MOD had plans to purchase AICW systems in around 2010-2012.
