Metal Storm Weapons are a series of proposed (and prototype) weapons created by the Australian company Metal Storm Ltd. These weapons use stacked rounds in a single barrel with electrochemical ignition, allowing for enormously high fire rates due to a lack of moving parts. While quoting a cyclic fire rate of any kind is slightly misleading (since these weapons have no action and therefore no cycle of function) their headline proof-of-concept demonstrator, a 36-barrel rig called "Bertha," fired 180 rounds at a total fire rate of one million rounds per minute (ie, 5 rounds from each barrel at ~27,777 RPM), making it the fastest-firing gun in existence. This rig had notable pressure problems due to firing rounds while the preceding round was still inside the barrel, and was not a practical weapon system. The Metal Storm VLE pistol appears to have also essentially been a proof of concept demonstrator to show how much the technology could be miniaturised.

The technology's main shortcomings are reloading and varying ballistics; a Metal Storm weapon must have an entire pre-loaded barrel or barrel section replaced each time it is empty, and since the rounds are stacked in the barrel, each successive round travels down a longer barrel and therefore has slightly different ballistics. This has largely limited practical applications of the technology to mortars and repeating grenade launchers where varying accuracy is not a major concern.

The technology does not seem to have been particularly successful; while Metal Storm produced a range of concepts and demonstrators, their largest contract appears to have been supplying 500 MAULs and 5,000 less-lethal barrels to Papua New Guinea for law enforcement use, and the company's shares were suspended in July 2012 and Metal Storm Ltd placed into voluntary administration. Their US-based subsidiary Metal Storm Inc filed for Chapter 7 bankruptcy in October 2014.
