Right after World War II. United States Air Force felt much needed improved gun systems for their aircraft; old weapons systems like the M2.50 caliber were becoming obsolete by aircraft, and they 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 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 be mounted on an aircraft weapon. The gun, known as the M61 20MM canon, started serving in the USA Army and Air Force.


The M61 weapon system was redesigned as the helicopters came into modern warfare, and it was 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 helicopters like OH-6 Cayuse, AH-1 Cobra, and 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 )

The GAU-17 is currently serving on the UH-1N and H-60 helicopters, as well as on a number of American aircraft, helicopters, and boats.GAU-17 system works on the system consisting of a six-barrel rotary M134D gun system, barrels made of titanium suppressors, and the barrel unit rotating counterclockwise from behind the trigger.GAU 17 weapon system is highly demanded and highly prized in the US military.


In conclusion, the Gatling Gun, particularly the M134 Gau-17, has evolved significantly since its inception in the 1880s. This weapon has proven its effectiveness and adaptability, from its electrically driven rotary breech to its use in modern warfare. Serving in various armed forces worldwide is a testament to the continuous advancement in military technology. The GAU-17, an enhanced version, is a highly prized asset in the US military, demonstrating its ongoing relevance and importance in today’s defense landscape.
