The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). [2] It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor.
The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm × 102 mm (0.787 in × 4.016 in) rounds at an extremely high rate (typically 6,000 rounds per minute).
The magazine can hold 1,174 rounds, although 1,150 is the typical load-out. Muzzle velocity when firing armor-piercing incendiary rounds is 1,013 m/s, almost the same as the substantially lighter M61 Vulcan's 20 mm round, giving the gun a muzzle energy of just over 200 kilojoules.

The modern M2 can fire up to about 800 rounds per minute with a maximum range of 6,800 meters and a more accurate maximum effective range of about 2,000 meters. 2. M1911
At 50 rps (3,000 rpm), a five-second burst from an M134 Minigun would use approximately 6.3 kilograms (14 lb) of 7.62 mm ammunition; this alone would make it an impractical weapon for infantry who have to carry a reasonable supply of ammunition with them. For this and other reasons, weapons with such high rates of fire are typically only found ...
The Block 1A and newer (pneumatic driven) CIWS mounts fire at a rate of 4,500 rounds per minute with a 1,550-round magazine. The velocity of the rounds fired is about 3,600 feet per second (1,100 m/s). The rounds are armor-piercing tungsten penetrator rounds or depleted uranium with discardable plastic sabots. The Phalanx CIWS 20 mm rounds are ...
The Minimi has a manually adjustable gas valve with two positions, normal and adverse. The adverse setting increases the cyclic rate of fire from 700–850 rounds per minute to 950–1,150 rounds per minute and is used only in extreme environmental conditions or when heavy fouling is present in the weapon's gas tube.
Fastest rate of fire: 4 rounds per minute for 3 minutes. Sustained rate of fire: 1 round per minute. 9. M992 FAASV ©Public Domain / Wikimedia Commons. Max range: 14.2 miles (23 kilometers) — tied.
