7.62 mm M134 General Electric 'Minigun'

"Fires up to 6000 rounds per minute. 7.62 x 51 mm shells. 1.36 kg recoil adapters. Six muzzle velocity of 869 m/s."
  - Elvis in They came and ate us by Robert Rankin

The problem is that you need three heavy-duty 12V truck batteries to power the gun, or alternately a 28V 115 amp power cable. Would make even a macho man like Blaine clumsy... This is why it is mostly used in helicopters. This mean piece of equipment has been in some serious use in the books by Robert Rankin. The gun in Predator was actually a .223 calibre version.

The M134 "Minigun"

What is it?

The M134 is a multi-barreled machine gun used in aircraft for the U.S. Army, U.S. Navy (known as the GAU-17/A), and the U.S. Air Force (GAU-2B/A). It is the 7.62mm successor of the Vulcan M61A1 20mm cannon.

Who makes it?

The original manufacturer of the M134 is General Electric in 1960 for the U.S. Army. to be used in The Vietnam War. Ktinga has written that the UH-1 Huey helicopter is armed with them, but that's just the tip of the iceberg. The ACH-47A "Guns-A-Go-Go," the AH-1G "Cobra," are also some of the helicopters armed with this gun to name a few.

Is it still made/used?

After January 1971, GE made and 10,000 of these miniguns and stopped further production. Therefore, the U.S. Army does not use them nowadays. However, the appropriate people in the government (that is, the military) can still buy a remade (or should I say, reborn) version of the M134 from Dillon Aero, Inc. of Scottsdale, AZ.

The magazine Soldier of Fortune has made a review of this new iteration of the minigun, with Technical Editor Peter G. Kokalis recalling his memories of using the GE model in El Salvador being a shame because of the jamming and what not. The test firings from this new minigun is, of course, better than the original and jamming recovery is quicker.

The United States Army's Special Operations folks have in their arsenal a modified version of the UH-60 Black Hawk. The MH-60K has a load of improvements for long-range deployments as well as support for .50-caliber machine guns or a pair of M134 miniguns. I'm not surprised if the book Black Hawk Down mentioned its reliability and lethality.

What are the statistics?

  • The M134 runs on a 28-volt power source, be it from a helicopter or stand-alone using the appropriate battery.

Where have I seen one?

Jesse "The Body" Ventura carried it (connected with truck batteries) in Predator. In the movie Terminator 2, the T-800 (Arnold Schwarzenegger) uses the minigun to fire at police cruisers while the Cyberdyne building is in the process of being ransacked of the Terminator parts, then destroyed. If you watched The Matrix, Neo fought Agent Smith with an M134 mounted in a helicopter.
