Right after World War II. United states air force felt much needed improved gun system for their aircraft, old weapons systems like the M2.50 caliber were becoming obsolete by aircraft and needed a more lethal weapon with increased range.

In the 1880s, Richard J Gatling re-introduced the multi-barreled rotary weapon. Under the Army Ordnance, Research, and Development. Early tests gave the vintage Gatling gun, but when powered with the electric motor in place of the usual hand crank, it showed more power, and it was able to achieve fire rates of 4,000 rounds per minute.

The general electric company created this weapon under the project name “Vulcan” in 1946. assigned to produce t guns in the caliber prototype, assembled in three different calibers 60 calibers, 20mm, and 27mm. After the series of tests, the 20mm was chosen for another set of tests to know whether it could mount on an aircraft weapon. The gun was known as M61 20MM canon and started serving in the USA Army and Air Force.


The M61 weapon system was redesigned as the helicopters came into modern warfare, Redesigned to use the helicopters. After that, the M134 was introduced. This new weapon system was similar to the M61A1 but fired smaller 7.62mm percussion primed rifle cartridges fired at 6,000 rpm.

During the Vietnam war, M134 was used in the helicopters like OH-6 Cayuse, and AH-1 Cobra, UH-1 Iroquois. In those helicopters, Only the pilot and co-pilot could fire that weapon. 

The GAU-17 is similar to the M134. The only difference is that GAU-17 is more lethal, and it can fire at high ( 4000 rpm) & low ( 2000 rpm )
