What is minigun?

The minigun is a multi-barreled, high-rate-of-fire, electrically powered, rotary machine gun. It typically fires rifle caliber ammunition (e.g., 7.62x51mm NATO or 5.56x45mm NATO).

Here's some key information:

• Operation: The minigun operates on the Gatling principle, using multiple barrels that rotate to cycle through the firing sequence. This allows for a much higher sustained rate of fire than a single-barreled machine gun. (Operation)
• Rate of Fire: Miniguns are characterized by their extremely high rate of fire, typically ranging from 2,000 to 6,000 rounds per minute.
• Power Source: They are electrically powered, requiring an external power source to operate the rotary mechanism.
• Ammunition: Common calibers include 7.62x51mm NATO and 5.56x45mm NATO, but other calibers have also been used. (Ammunition)
• Applications: Due to their high rate of fire and the need for an external power source, miniguns are typically mounted on vehicles, aircraft, and naval vessels. They are used for suppression fire, area denial, and anti-personnel roles.
• History: The original Gatling gun, invented in the 19th century, was a hand-cranked predecessor to the modern minigun. The modern electrically powered minigun was developed in the mid-20th century for use in the Vietnam War. (History)
• Manufacturers: Several manufacturers produce miniguns, including General Dynamics, Dillon Aero, and Garwood Industries.
