'''Macro cannons''' are a type of [[Macroweapon]] and the largest form of [[Auto Weapons|auto-weaponry]], much heavier even than the [[autocannon]].{{Fn|1}}

On spaceships, dozens of individual Macrocannons are grouped together as a [[Weapons battery|Macrobattery]], forming a single broadside.{{Fn|2a}} These voidborne cannons are significantly larger than their terrestrial counterparts and are able to accurately hit targets at distances ranging from tens of thousands of kilometres{{Fn|8}} to half a million kilometres.{{Fn|9}} Some void-based [[Macro-weapon|Macro-weapons]] have an effective range comparable to a [[Nova Cannon]], which fires projectiles close to the speed of light{{Fn|7}} at targets up to two-light minutes away.{{Fn|10}}
