What machine gun is the Worlds fastest?

Answer 1

The Fastest gun in the world is designed by Metal Storm. It is a 36 barrel prototype which could fire about 1,000,000 rounds per minute. (16600 bullets a second.) The fact that the bullets are stacked behind each other enables it to fire that fast. This weapon can be mounted on jeeps, planes, helicopters, tanks etc..

The fastest machine gun in the World is the Metal Storm. It fires 1660 bullets in one second up to 1 million rounds in 1 minute. The Metal Storm open fires automatically without having someone to crank it up. Metal Storm is an unmanned machine gun that is operated by the computer. No other machine gun in the World can fire as fast as the metal storm at that kind of firing speed. The metal storm is much faster than any other machine guns and can spray more bullets very quickly.

AnswerMetal Storm is NOT a machine gun. It is a modern version of what is called a "volley gun"; a classical example of the volley gun is the French mitrailleuse (a contemporary of the Gatling Gun). All rotary cannons (such as the Gatling Gun or miniguns) are also NOT machine guns.

Machine guns consist of a single barrel, with an action that cycles through each shot individually. Used generically, "machine gun" also would include things such as autocannons (and the related chain gun), and also automatic rifles, submachineguns, automatic pistols, and any similar device which uses a single barrel to cyclically fire through an ammunition supply (either a magazine or belt).

In most contexts, a machine gun refers to a gas-recoil auto-feed action, where the expanding gas from the propellant of the just-fired round opens the bolt, ejects the cartridge case (if there is one), loads the next round into the chamber, and cocks the firing pin. This processes is repeated as long as the trigger is held down. The main difference between guns typically labeled a machine gun and an automatic rifle (or similar small arm) is that a machine gun is designed for longer periods of sustained automatic fire, and may in fact not be able to be fired in a semi-automatic mode. The difference between a machine gun and an autocannon is generally the size of the bullet - those of less than 20mm caliber are labeled machine guns, and those of 20mm or higher caliber are autocannons (it's a generally arbitrary line).

Keeping the aforementioned characteristics in mind, the fastest-firing true machinegun is likely the WW2 Soviet ShKAS, with the Ultra-ShKAS variant being able to fire very short bursts (50 rounds or less) at a theoretical rate of 3,000 rounds per minute. However, the Ultra-ShKAS suffered serious quality control problems, and was never really deployed.

The highest-cycling practical machinegun (i.e. one that saw significant service) is likely the WW2 German MG42, with a cyclic rate of almost 1600 rounds per minute. With a well-designed belt feed system, and a easily-changed barrel, an MG42 could maintain sustained burst fire (i.e. 100-150 round bursts, 5-10 seconds apart) for several minutes, a far larger volume of fire than any other machine gun.

However, it has been shown that high rates of fire in machine guns are generally not useful. Unless the target is moving extremely quickly (i.e. aircraft speeds), a high rate of fire will place all bullets in virtually the same place.

For example, the above MG42 tended to fire a 5 second burst of about 100 bullets. The gun must then wait another 5-10 seconds (to cool slightly) before firing again. This means that those 100 bullets almost certainly covered an area of no more than a 10-20 horizontal feet at a typical engagement range of 400 yards. Compare this to a current-day machine guns, which have cyclic rates of 400-800 RPM, but can fire 20+ seconds bursts (shooting roughly the same number of bullets). At 400 yards, such a burst could spread 50+ feet. What this boils down to is that a moderate rate of fire has a better per-bullet chance of hitting something - the bullets are spread out more, covering more area, giving each bullet a greater chance of hitting something.

Answer 2

The World's fastest machine gun is Metal Storm. It's 36 barrel prototype gun that can fire up to 1,000,000 rounds per minute(16 thousand rounds per second).
