The M134 Minigun is a 7.62 mm, six-barreled machine gun with a high rate of fire (2,000 to 6,000 rounds per minute), employing Gatling-style rotating barrels with an external power source. The term "Minigun" has popularly come to refer to any externally-powered Gatling gun of rifle caliber, though the term is sometimes used to refer to guns of similar rates of fire and configuration, regardless of power source and caliber. Specifically, minigun refers to a specific model of weapon, originally produced by General Electric. The "Mini" of the name is in comparison to designs that use a similar firing mechanism but larger shells, such as General Electric's earlier 20 mm M61 Vulcan, and "gun" referencing the delineation between a cannon, that of a caliber higher than 20 millimeters--and gun--within certain ranges. The development of a
rifle-caliber, externally powered Gatling type machine gun was commenced by
weapons branch of the US-based General Electric Corporation in 1960, following
the successful development and fielding of the 20mm M61 Vulcan automatic gun
(used in aircraft and AA applications). First prototypes of the 7.62mm Gatling-type
machine gun were fired in 1962, and in late 1964 first 7.62mm machine guns,
dubbed 'the Minigun', were mounted on AC-47 Gunship aircraft for combat trials.
Following the definitive success of the first 'Gunship' aircrafts armed with
Miniguns, GE commenced mass production of the new weapon, officially adopted by
US Army as M134 Minigun and by US Air Forces as GAU-2/A machine gun. By 1971
more than 10,000 Miniguns were produced and delivered to US Armed forces. Most
were used in airborne applications, installed in a variety of side- or
forward-firing mountings aboard aircrafts and helicopters (AH-1 Cobra, UH-1
Huey, HH-53 Green Giant and others). Some Miniguns also were installed on
riverine crafts, used by US Navy and Special forces in Vietnam.Thanks to its
sustained-fire capability and high rate of fire, Minigun weapons provided
excellent suppressive and area denial capabilities. It must be noted, however,
that infantry applications of the Miniguns were very limited due to the weight
of the system and its requirement for external electric power. In most cases,
Minigun machine guns were (and still are) mounted on high mobility vehicles as
anti-ambush weapons. The M134 Minigun is an externally operated weapon which uses electrical motor drive to operate its action. Typical power requirements for 3,000 rounds per minute (50 rounds/second) rate of fire are 24-28 V DC, 58 Amp (~1.5 KWt); with increase of rate of fire power requirements rise accordingly. The gun operates on Gatling principle, that is it employs a rotary cluster of six barrels, each with its own bolt group. Bolts are moved back and forth behind each barrel as their operating roller passes an internal curved track machined inside the receiver cover. Typically, the topmost barrel in the cluster has its bolt fully open and the bottom barrel in cluster has its bolt fully closed, locked and firing pin released to fire the loaded cartridge. Barrel locking is achieved by the rotary bolt head. Since the gun operates on external power, it is immune to dud / misfired rounds, which are ejected during the normal cycle of operation. Feed is provided either by linkless chute or by the linked ammunition, In the latter case, a powered feeder/delinker module is installed on the gun; it receives necessary power through the gear from the gun motor. To properly operate the gun, it is fitted with electronics control box, which, in the case of manually controlled installation, has an 'master arm' switch and fire controls (triggers). Typical feed arrangement uses a large container holding some 1,500 (full weight ~ 125 lbs / 58 kg) to 4,500(full weight ~ 295 lbs / 134 kg) rounds, with maximum capacity reaching well over 10,000 rounds per gun in certain heavy helicopter installations (such as used in CH-53 and CH-47 during Vietnam war). The container is connected to the gun via the flexible chute. If chute is overly long, an additional electrical feed booster is installed on the ammunition container.
