miniguns

A minigun is a type of Gatling-style rotary barrel machine gun that is typically electrically powered. The name "minigun" is a trademark of General Dynamics Ordnance and Tactical Systems, but the term has become a generic term for similar electrically powered rotary barrel weapons. Miniguns are known for their extremely high rate of fire, often thousands of rounds per minute. This high rate of fire is achieved through the rotation of multiple barrels, which are sequentially fired and cooled as they spin. This design prevents barrel overheating and allows for sustained fire.

The original M134 Minigun, developed in the 1960s, fires 7.62x51mm NATO rounds and is commonly mounted on aircraft, helicopters, and vehicles, as well as some naval vessels. Its firepower makes it effective for suppressive fire and anti-personnel roles. The rapid firing cycle allows for a dense area of fire, making it difficult for targets to evade. Ammunition is typically fed from an external source, such as a linked ammunition belt or a specialized ammunition feed system.

While the minigun's primary advantage is its immense rate of fire, this also means it consumes ammunition at an exceptionally high rate. Its size, weight, and power requirements often limit its use to platforms where these factors are less critical. Smaller, lighter versions exist, as do weapons chambered for different calibers. The complexity of the weapon system, requiring external power and a robust feeding mechanism, contributes to its specialized applications.
