The company is headquartered in Brisbane, Australia and incorporated in Australia.

Metal Storm is working with government agencies and departments, as well as industry, to develop a variety of systems utilising the Metal Storm non-mechanical, electronically fired stacked ammunition system.
Metal Storm's weapon technology uses computer-controlled electronic ignition and a system of stacked projectiles, to achieve a completely non- mechanical gun that is very lightweight and compact, providing a very high firepower to weight ratio. The Metal Storm weapons system utilises multiple barrels mounted together on one platform which allows varying munitions types to be deployed in a single, low cost, lightweight weapon system. Firing the weapons by electronic ignition requires no moving parts, allowing reliable long term unattended weapon operation.
