Cannons are one of the three available weapon types. The others being the Single Barrel and the Battery. They are installed as clusters in the fixed forward facing gun slots. While cannons fire slowly, the have high penetration power, often capable of damaging a hull with armor and shields still intact, sometimes even causing extensive damage to critical systems.

Cannons are a tactical-oriented weapon, traditionally mounted on bombers and capital ships, which provide the "punch" of a fleet. Their low fire rate makes them less suitable against small fast targets.
