The SN machine gun of Russian origin is a derivative of the Revolver Cannon concept with capabilities of firing up to 3,600RPM.


Revolver cannon firing sequence.

A Revolver cannon is a type of autocannon commonly used as an aircraft gun. It uses a cylinder with multiple chambers, like those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process, but this is by no means universal. A revolver cannon differs from a Gatling gun in having only a single barrel, so the spun weight is lower and lends itself to gas operation. Automatic revolver cannons have been produced by many different European manufacturers, whereas the U.S., and to a lesser extent Russia, generally favor the Gatling gun.
