The Heavy Sub-Capital Cannon was a massive weapon, displacing as much weight as a combination of its Light and Medium siblings. The relatively short range of the weapon was more than compensated for by its large damage potential. Considering its size, the Heavy Sub-Capital Cannon offered a good amount of damage when compared to the NAC/10, but the latter's range and heat advantage made it more popular for battles between WarShips.
