Automatic Cannon
Also known as an autocannon or chain gun, an automatic cannon is a machine gun scaled up to calibers of 20mm or larger. Ground vehicles and helicopters use the same basic light designs. Air superiority fighters carry Gatling-type rotating cannons, needing the high rate of fire to ensure hits while moving at 500 miles per hour or faster (weapon Traits already reflect the accuracy balance between a 1,200- RMP rate of fire and the assumed high speed of the shooter). Ground attack fighters, which need both speed and power to kill enemy armored vehicles, carry the heaviest models possible. All automatic cannon are capable only of autofire, not single shots. Most carry a mix of ammunition types, which is reflected in the “Special Effects” column of the following table.
