M134 Minigun Sound – Aircraft Weapons SFX Library

The M134 Minigun Sound is a sound of 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. Several branches of the U.S. military use M134 Minigun. United States Army use M134 and XM196, but the U.S. Air Force and U.S. Navy – GAU-2/A and GAU-17/A.

The “Mini” in the name is in comparison to designs that use a similar firing mechanism but larger shells, such as General Electric’s earlier 20-millimeter M61 Vulcan, and “gun” for a caliber size smaller than that of a cannon, typically 20 mm and higher.

The electric drive rotates the weapon within its housing, with a rotating firing pin assembly and rotary chamber. The minigun’s multi-barrel design helps prevent overheating, but also serves other functions. Multiple barrels allow for a greater capacity for a high firing rate, since the serial process of firing, extraction, and loading is taking place in all barrels simultaneously. Thus, as one barrel fires, two others are in different stages of shell extraction and another three are being loaded. The minigun is composed of multiple closed-bolt rifle barrels arranged in a circular housing. External power source, usually electric, pneumatic, or hydraulic rotate the barrels. Gas pressure or recoil energy of fired cartridges power other rotating-barrel cannons.

The machine gun sound consists of the firing start sound – [START] file, [LOOP] audio file 10 seconds long and the ending file – [END], which should be played at the end of the shooting. The Aircraft Weapons SFX Library includes 51 audio files.
