The AICW (Advanced Infantry Combat Weapon) is a joint development of the Australian DSTO (Government operated Defence Science and Technology Organisation), and private companies Metal Storm and Tenix Defence. 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 copmponent 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, receiver has been upgraded to receive the G/L module at the top, and the buttstock has been enlarged to accomodate G/L electronic fire contol 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 demonstartions 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 compas), or with Vinghog Vingsight Fire Control System. At the present time (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 demonstartors", that completed first live-fire trials (as a complete system) in the summer of 2005. Current Australian MOD plans state that ADF may start to purchase AICW systems in around 2010-2012.

Thales EF88 / F90 assault rifle (Australia)

F90 assault rifle, also known as EF88 (enhanced F88) is an evolution of the F88 assault rifle, which was adopted by Australian and New Zealand armed forces during late 1980s. The original F88 rifle is a licensed copy of the Austrian Steyr AUG rifle, and it was produced in Australia at Australian Defense Industries factory in Lithgow. Today this same factory is operated by the Thales Australia, which developed EF88 / F90 rifle as a next weapon for Australian army, as well as for export.

While internally and externally the F90 is still close to Steyr AUG, it has many distinctive upgrades and changes, developed by Thales to fulfill current and near-future requirements of Australian armed forces. The Thales F90 rifles were first displayed to the public in mid-2012, and initial production is scheduled for 2013.

The resulting weapon is said to be much more reliable and comfortable than original F88 / Steyr AUG rifle. It is also noticeably lighter: standard F90 with 50 cm / 20” barrel is about 0.5 kg / 1.1 lbs lighter than standard F88 rifle; with new 40mm underbarrel grenade launcher installed, resulting weapon is more than 1.6 kg / 3.5 lbs lighter than F88 rifle equipped with M203PI grenade launcher.

F90 / EF88 assault rifle is gas operated, selectively fired weapon of bullpup layout. It uses polymer housing with improved shape of buttstock (including the new buttpad and added comb for better cheek-weld). Gas operated, short-stroke, rotary bolt action is similar to that of original Steyr AUG, but the gas block is modified. Aluminum alloy receiver is also modified to improve reliability and reduce weight. Ejection ports and ejection covers also modified to ensure reliable extraction under all conditions.

Unlike all previous versions of the Steyr AUG, the F90 has non-removable barrels, cold-hammer forged and externally fluted. Standard F90 rifles are offered with 50 cm / 20” barrels; other versions include carbines with 40 cm / 16” barrel and CQB variants with 36 cm / 14.1” barrel. Other clearly visible changes include extended Mil-Std (Picatinny) rail at the top; bottom rail has replaced original folding forward grip of the Steyr AUG / F88. Third accessory rail is mounted on the right side of the weapon. Trigger guard is redesigned to accept new, specially designed 40mm Underbarrel Grenade Launcher. This lightweight add-on weapon can be quickly attached directly to the bottom rail of the host rifle, and then easily removed when not required. Less visible changes include addition of the bolt hold-open device to facilitate faster reloads. F90 will feed from the same proprietary translucent magazines, made from polymer as the original Steyr AUG / F88 rifles, although optional STANAG-compatible version is said to be available in the near future. Basic sighting is provided by Trijicon ACOG optical sights with 1.5X or 3.5X magnification, although sights can be easily changed, thanks to MilStd mounts.
