Metal Storm Limited was a research and development company based in Brisbane, Australia that specialized in electronically initiated superposed load weapons technology and owned the proprietary rights to the electronic ballistics technology invented by J. Mike O'Dwyer.^[2][3][4] The Metal Storm name applied to both the company and technology. The company had been placed into voluntary administration by 2012.

Technology[edit]

Metal Storm used the concept of superposed load; multiple projectiles loaded nose to tail in a single gun barrel with propellant packed between them. The Roman candle, a traditional firework design, employs the same basic concept; however, the propellant continues to burn in the Roman candle's barrel, igniting the charge behind the subsequent projectile. The process is repeated by each charge in turn, ensuring that all projectiles in the barrel are discharged sequentially from the single ignition. Various methods of separately firing each propellant package behind stacked projectiles have been proposed which would allow a 'shoot on demand' capability more suitable to firearms.^[5]

J. Mike O'Dwyer, an Australian inventor, observed that these methods did not eliminate the problem of unintended propellant ignition caused by highly pressurized hot gases 'leaking' past the remaining projectiles in the barrel (blow-by) and igniting their charges. J. Mike O'Dwyer's original Metal Storm patents demonstrated a method whereby projectiles placed in series along the length of a barrel could be fired sequentially and selectively without the danger associated with unintended propellant ignition.

In the original Metal Storm patents, the propellant immediately behind the projectile closest to the muzzle of the gun barrel was ignited by an electronically fired primer, the projectile was set in motion, and at the same time a reactive force acted on the remaining stacked projectiles in the barrel, pushing them backwards. By design, the remaining projectiles would distort under this load, expanding radially against the gun barrel wall. This created a seal (obturation), which prevented the hot propellant gases (expanding behind the lead projectile) from leaking past them and prematurely igniting the remaining propellant charges in the barrel. As each of these propellant charges was selectively (electronically) ignited, the force 'unlocked' the projectile in front and propelled it down the gun barrel, and reinforced the radial expansion (and hence the seal) between the projectiles remaining in the barrel and the barrel wall.^[6]

Subsequent designs discarded the 'distorting shell sealing against the barrel' concept in favour of containing the propellant in 'skirts' that form the rear part of each projectile. These skirted projectiles differ from conventional shells and cartridge units in that the skirts are part of the projectile, and in that the skirts are open-ended (at the rear). The rearward seal to the skirt is provided by the nose of the following projectile in the barrel. As in the previous design, the firing of a projectile results in a rearward impulse on the remaining projectiles stacked in the barrel. This results in the skirts of the remaining shells in the barrel being compressed against the following shell heads, effectively creating a seal that prevents hot gases in the barrel triggering unintended propellant ignition ('blow-by') along the length of the barrel. Metal Storm also introduced inductive electronic ignition of the propellant, effectively from outside the barrel.^{[citation needed]}

Products[edit]

A minigun with a belt of separate firing chambers also exists.^[7]

The Multi-shot Accessory Under-barrel Launcher (MAUL) is an electronically fired, 12-gauge shotgun for use as an accessory weapon to a range of weapons, such as the M4 or M16 rifle, or as a stand-alone 5 shot weapon, providing a range of lethal (buckshot and slug) and non-lethal (blunt impact, door breaching, and frangible) munitions, all preloaded in 5 round 'stacked projectiles' munition tubes. Metal Storm reported^[8] the first shoulder-firing of the MAUL during tests on 24 April 2009 at its test facilities in Chantilly, Virginia.

Metal Storm has created a 36-barreled stacked projectile volley gun, boasting the highest rate of fire in the world. The prototype array demonstrated a firing rate of just over 1 million rounds per minute for a 180-round burst of 0.01 seconds (~27,777 rpm / barrel). Firing within 0.1 seconds from up to 1600 barrels (at maximum configuration) the gun claimed a maximum rate of fire of 1.62 million RPM and creating a dense wall (0.1 m between follow-up projectiles) of 24,000 projectiles.^[9][10][11]

The 3GL is a semi-automatic grenade launcher firing individually loaded grenades, with up to 3 rounds being able to be loaded and fired semi-automatically. It can be attached to weapons via RIS rails or to a stand-alone folding stock.^[11]

History[edit]

Sometime in 1983, Mike O'Dwyer sold his trade business in order to work on Metal Storm.^[9]

In June 1997, the first 36-barrel prototype was unveiled.^[9][11]

In 2000, Chinese agents approached Michael O'Dwyer and offered him US$100M to go to China to develop the technology.^[12][13] O'Dwyer refused and informed the Australian government of the approach. Nonetheless, the concept behind the weapon system generated some interest in China such that research was carried out to investigate the utility of such a weapon for use onboard naval vessels and armored vehicles, in the latter case even for the purpose of intercepting incoming anti-tank guided missiles.^[14][15]

In June 2003 Metal Storm entered into an agreement to provide technology to Thunderstorm Firefighting Pty Ltd to help develop a civilian application of its technology to help with bush fire fighting activities. On 27 June 2003, Metal Storm received funding from the American military.^[16]

In 2005, O'Dwyer left the company with a $500,000 payout and an intention to sell half his stake—then valued at $43m—but he could not find a buyer.^[11][17]

On 19 November 2007, it was announced that the US Navy was buying Metal Storm grenade 'barrels'.^[11]

Hamster ball game unblocked. In August 2010, Metal Storm signed a contract with a value of US$3,365,000 with Papua New Guinea's Correctional Services Minister Tony Aimo to supply 500 MAULs and 10,000 less-lethal barrels for use by correctional services officers.^[18]

Metal Storm requested their shares be suspended from trading on 20 July 2012.^[19] As of 26 July 2012, the company has been placed in voluntary administration.^[19]

In late 2015 DefendTex, an Australian-based Defence R&D company acquired the intellectual property, trademarks and other assets of Metal Storm with a view to the continued development and commercialisation of the technology.^[20]

In July 2018, DefendTex entered a joint partnership^[21] to provide weapon pods for the experimental Cerberus UAV.
