It has no moving parts. Yet, it can fire standard, small-caliber projectiles from multiple barrels at speeds up to one million rounds per minute. Is it still a gun?

Its creators call it Metal Storm. No moving parts mean no jams in the traditional sense and a quiet operating mechanism. The high rate of fire is not just a function of the number of barrels. The cartridges are initiated with an electronic impulse.

Building on earlier technology, successfully demonstrated over the past three years, Metal Storm continues to try to drag small arms technology—some might suggest kicking and screaming—into the computer age. Inventor Michael O’Dwyer said his Australian-based company, also named Metal Storm, has found additional applications and new ways to incorporate other technologies with its own.

Metal Storm still is ranked as a high-risk technology among the latest in a string of efforts to achieve a real leap ahead in small-arms technology. Prototypes have been demonstrated to the apparent satisfaction of the U.S. Defense Advance Research Projects Agency. Metal Storm’s owners have received more than $50 million in development dollars from the U.S and Australian governments.

Looking beyond the traditional, a single, or multi-barreled Metal Storm device could be added to an existing weapon on a Picatinny rail, or current optics and fire-control systems could be added to a Metal Storm platform. The company has taken its 9 mm pistol and incorporated a key control device to create its own version of a “smart gun” for possible law enforcement applications. This variant could fire multiple rounds with a single trigger pull. On activation, the weapon could send out a “help” signal on a radio frequency to call for backup.

The Australian company is partnered with the U.S.-based SAIC in a DARPA-led contract to develop a new, lightweight advanced sniper rifle, based on Metal Storm technology. Rather than depending on larger calibers—such as .50 caliber or 20 mm—the Metal Storm advanced sniper rifle would use .45 caliber ammunition, with thousands of rounds fired at a high rate of fire.

The ammunition developed for the sniper version of Metal Storm comes in two versions. One has a .17 caliber tungsten sabot fin stabilized projectile. The second variation has a .22 caliber sabot round that is spin stabilized. Both variants are caseless and electronically primed.

Some of the advantages of the sniper application noted by its developers include a rapid reload, since the rounds come in a pre-loaded barrel. This same technology allows the shooter to quickly change calibers or ammunition type. It also offers the user the option to make a quick shift to less-than-lethal, as a scenario evolves. Because Metal Storm can be programmed to fire multiple rounds with a single trigger pull at an extremely high rate of fire, it is conceivable that a sniper could deliver multiple rounds, a double or triple tap, at long range, with no recoil between rounds.

Metal Storm’s creators reduced the rate of fire in the sniper version to a more manageable 60,000 rounds per minute to improve the accuracy of a sniper rifle version. The company has been experimenting with the sniper rifle for the past year.

Australia’s Defense Science and Technology Organization is looking at various applications for the technology, including area denial, vehicle self-defense and a close-in weapon system. The company also is looking at civilian applications, such as firefighting.

Love your work. Commenting on Metal Storm. Can you get me one? I just need a small version, say only to fire about three thousand rounds max.

But seriously, about Metal Storm, the logistical problems with it (and the reason that it probably won't be an immediate threat to our lives) are the very fact that to have no moving parts, it has so much stationary metal that it becomes too heavy for normal use. I'm writing from a soldier's perspective, I have been a US Army soldier.. even a cheesy but nonetheless timeless M-16 becomes tiresome after about the fifth mile. Just think about the weight of the ammunition alone. I could see Metal Storm mounted on a building, guarding the entranceway to the last ketchup cache or something like that.

It did however inspire me to comment. I wonder how you came across it?
