An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber (20 mm/0.79 in or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles fired by a machine gun.
The R-23 cannon and its unique telescoped ammunition remained a military secret for a long time. This can be partially explained by the fact that the R-23 cannon was used in outer space, arming Salyut 3. The R-23 cannon was known only in the Soviet Union until the Tu-22 bomber was exported to Iraq and Libya during the 1970s.

Introduced in 1942, compared to the earlier Type 98 20 mm AA machine cannon, Type 2 20 mm had higher maximum rate of fire, could be elevated to 95 degrees and had a central fire-control system. [3] The central fire-control system developed for the Type 2 could control and direct six of the guns at once.
The NR-23 is a single-barrel, short recoil-operated 23 mm (0.90 in) cannon. It was similar to the NS-23 but mechanical improvements increased its rate of fire by more than 50%. Its theoretical rate of fire was 850 rounds per minute, although United States Air Force tests of captured weapons achieved an actual rate of fire of only 650 rounds per ...
The 60mm HVMS autocannon was designed as an infantry support gun mounted on light armored vehicles.. The project commenced in 1977, originally as a joint development between IMI Systems of Israel and OTO Melara of Italy, whereby IMI Systems were expected to develop the gun and ammunition, and OTO Melara the autoloader and a lightweight two-man turret which could be mounted on a variety of ...
The round was derived from the 14.5×114mm round by necking it out to 23 mm. [1] The original rounds used a lower power charge of 33 g of sw 4/7 powder and achieved 690 m/s at a maximum pressure of 294.3 MPa. In 1954 an improved ammunition was introduced, featuring better projectile design and ballistic properties.
One of the first American attempts at a gun pod was the .50-calibre machine gun conformal-mount "blister" pod on the B-25 MitchellA gun pod is a detachable pod or pack containing machine guns, autocannons, revolver cannons, or rotary cannons and ancillaries, mounted externally on a vehicle such as a military aircraft which may or may not also have its own guns.
