Dude, This Just LOOKS Wicked

The Navy is testing a new weapons technology that is astounding.

Metal Storm Reaches Navy Test Range

Brisbane, Australia-based Metal Storm has delivered a four-barrel weapon to the Naval Surface Warfare Center for testing that uses a small electrical current instead a conventional firing pin to deliver stacked rounds at an astounding rate.

How astounding? Try 1 million rounds per minute. That's the rate, by the way, not the volume; still, there's no way you want to be anywhere near the wrong end of one of these puppies.

…The projectiles are stacked in-line in the barrel--nose to tail--so there are no magazines, no shell casings and no mechanical components.

There is footage of some of the testing embedded in the linked article. You really ought to watch it. It is mind blowing. It would be a bad day indeed to be downrange from this weapon. I would think that they would eventually be able to fire on simultaneous targets. The thought of being downrange is not pleasant at all.
