Update: Edited with readable pictures.
From NA Player IKU19.
“Min” is the flat fee you get charged despite not taking any damage (also known as a “Fuel Fee”)
“Max” is the Fuel Fee + the total repair cost for when your ship sinks
“Shell” is the cost for an individual shell so a ship that has a turret with three barrels, the actual cost is shell * 3 then further multiply this with the amount of turrets.
“Torpedo” is the cost for an individual torpedo so a ship that has a launcher with five torpedo slots, the actual cost is torpedo * 5 then further multiply this with the amount of launchers.
“Plane” is the cost for one plane squadron, unlike “Shell” and “Torpedo” it is not the cost for one plane.
The premium ships are bolded.
The script took the most expensive equipment possible per hull, so some configurations especially ships that can upgrade artillery/torpedoes with the stock hull will have the upgraded armament as their value, not their stock torpedoes.
