About: 20mm Cannon   Sponge Permalink

An Entity of Type : dbkwik:resource/gdKV7OQE16rnujouVWB7oA==, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

Since 20mm is the cutoff point where most nations switch from bullets to shells, it has come to also generally be the cutoff point between weapons classified as a machine gun or a cannon. This can vary, however: for example, in WWII, Japan classified any weapon over 11mm as a cannon; thus, in Japanese records, their 12.7mm Ho-103 aircraft gun is classified as an autocannon, as it used explosive shells to overcome its lower muzzle velocity compared to American 12.7mm/.50BMG weapons). A machine gun does not fire shells, so historically a weapon that fires shells below 20mm can be a cannon. A true definition will always mention whether the weapon fires bullets or shells in addition to its caliber.

A machine gun does not fire shells, so historically a weapon that fires shells below 20mm can be a cannon. A true definition will always mention whether the weapon fires bullets or shells in addition to its caliber. A very small number of anti-tank rifles have been produced in 20 mm and larger calibers. Many but not all 20 mm rounds have an explosive filling and detonating fuze.
