Docking Guns have no effect on Starship Scale combat.
Built 30,000 years before Star Wars: Episode IV A New Hope, the Star Forge was a huge. The cost of a Docking Gun is for the mount only- the gun itself is bought normally. Still, the Star Forge is one of the most impressive weapons in the Star Wars arsenal. The idea has occasionally been used on military vessels- adding heavy guns to docking bays to assist in efforts to offload troops onto a battlefield, for example. They draw power from the ship, operating as long as the ship has power, instead of requiring Power Packs. Docking Guns count as Heavy Weapons once installed (Regardless of their original weapon category). Deal Physical damage to target enemy with a 50 chance to inflict Defense Down for 2 turns. Any Character Scale Ranged Weapon can be added as a Docking Gun, though Light Repeating Blasters and Heavy Blaster Rifles are most common. Smugglers and pirates often add Character Scale weapons to fighters and freighters, in order to allow them to open fire while docked without risking blowing up an entire docking facility.
