The General Electric GAU-8/A Avenger is a 30 mm hydraulically driven seven-barrel Gatling-style autocannon that is primarily mounted in the United States Air Force's Fairchild Republic A-10 Thunderbolt II.
It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. The "Mini" in the name is in comparison to larger-caliber designs that use a rotary barrel design, such as General Electric's earlier 20 mm M61 Vulcan, and "gun" for the use of rifle ammunition as opposed to autocannon shells.
M61 Vulcan – 20 mm Gatling-type rotary cannon; M134 Minigun – American rotary machine gun; XM214 Microgun – American prototype 5.56 mm rotary-barreled machine gun; M197 electric cannon – 20 mm Gatling-type rotary cannon; GAU-12 Equalizer – 25 mm rotary aircraft autocannon; GAU-8 Avenger – American 30mm autocannon (since 1977)
In response to this requirement, the Armament Division of General Electric resurrected an old idea: the multi-barrel Gatling gun. The original Gatling gun had fallen out of favor because of the need for an external power source to rotate the barrel assembly, but the new generation of turbojet-powered fighters offered sufficient electric power ...
The GAU-13 was developed in the late 1970s for use in gun pod applications for fighter aircraft and attack aircraft use, primarily for air-to-ground and anti-tank attacks.. The GAU-13/A is a four-barreled rotary cannon based on the mechanism of the larger GAU-8, sharing the same massive 30 mm ammunition.
In 1946, a Model 1903 Gatling gun was borrowed from a museum and set up with an electric motor drive by General Electric engineers. During test firing, the 40-year-old design briefly managed a rate of fire of 5,000 rounds per minute. In 1949 General Electric began testing the first model of its modified Gatling design, now called the Vulcan Gun ...

The M197 electric cannon was developed primarily for use by United States Army helicopter gunships. Development began in 1967 after experience in the Vietnam War revealed the inadequacy of the 7.62 mm Minigun for gunship use. The M197 is essentially a lightened version of the General Electric M61 Vulcan cannon, with three barrels instead of
