In the new patch, when you hover the cursor over one of your ships it gives you weapon details. For the Kol Battleship It has three categories. Average Beam Damage, Average Autocannon Damage, and Average Laser Damage.
The Kol Battleship doesn't have lasers does it? At least not to my knowledge, unless thats their to reference the three big cannons on the side. However I thought those were just that, cannons.
