Advanced Individual Combat Weapon

The Advanced Individual Combat Weapon (AICW) was a prototype combination assault rifle and grenade launcher developed in Australia as a technology demonstrator.[1] The AICW combined a standard 5.56 mm assault rifle based on the successful Steyr AUG with a superposed load grenade launcher developed by Metal Storm.

History

The AICW was developed by the Defence Science and Technology Organisation (DSTO) in alliance with Metal Storm and Tenix Defence Systems, receiving funding primarily through the Australian Government's Capability and Technology Demonstrator (CTD) program.

The AICW aimed to provide the infantry soldier with the ability to fire multiple grenades without having to reload, and to switch between 5.56 mm ballistic rounds and 40 mm grenades without changing sights, trigger or stance, giving the operator more versatility and reduced reaction times in combat.

The 3rd generation AICW VX3 underwent live-fire testing in July 2005, engaging targets from a test-bed with both 40mm and 5.56 projectiles out to 300m[1][3]. Stephen Forbes, DSTO Scientific Officer in charge of the AICW CTD, reported that the AICW alliance was “pleasantly surprised” with the weapon's accuracy demonstrating the ability to consistently hit a door or window sized target at 100m. All component technologies, including new technologies such as recoil mitigation, sighting systems, and electronic fire control, were also considered to be successfully demonstrated.[1][3]

The weapon was not intended to enter service but rather as a concept demonstration to "generate ‘advance-thinking’ within the ADF about the future of small arms".[1] As such, development of the weapon ceased following the successful demonstration of the technology and the completion of the CTD program.

Comparisons with Similar Systems

AICW, with its stacked round grenade launcher, did not require conventional mechanical loading. This made the weapon more compact and potentially far lighter than other combination weapons like the American XM-29 OICW[4].

According to Stephen Forbes, the AICW compared favorably to the OICW, with a potential production version weighing as little as 7.5kg fully loaded after a predicted 380g weight reduction from the VX3 prototype. The AICW would retain 30 round magazines, overall length of 738mm and 450mm barrel, while the loaded OICW weighed 8.2kg with 20 rounds of 5.56×45mm NATO, a longer overall length of 890mm and a barrel length of 250mm which the DSTO considered ineffective due to reduced velocity and bullet fragmentation.[1] In comparing the ammunition, the explosive radius of the 40mm was also considered to be superior to that of the 20mm and the reduction in velocity deemed acceptable at expected combat ranges.

The AICW, not including sights and ammunition, would have represented increase in weight of up to 20% compared to the M203-equipped F88GLA in service with the ADF at the time. In return, the AICW offered a 25% higher grenade velocity and recoil mitigation for follow-up fire.[1]
