FireStorm and the Marine Corps.

Produced by Metal Storm Limited, an Australian defense company, the FireStorm is an electronically fired, multi-barrel 40mm platform. Features include interlocking mechanical and electrical systems for safe operation and light weight.

The weapon and mount together weigh 120 pounds, with the entire unit 21.9 inches tall and 28.6 inches long. The FireStorm can be mounted on anything from humvees to remote controlled robots. It possesses the capability to render less than lethal weaponry, or fire a volley of high explosive rounds at a rate of 6,000 rounds per minute firing from all barrels.

Ammunition is loaded in the tubes, capacity ranging from four to six rounds per tube, depending on the ammunition used.

First the Navy and now the Marine Corps seems to keep toying with the FireStorm concept.  Why no one has pulled the "trigger" yet is beyond me...
