Question about code line and file location

[Sorakiba]

I was wondering if anyone knew which files have the coding for the damage for torpedoes, deck guns, and flak cannons.

and maybe which lines of coding specifically, if the coding isn't plain, and simple to understand?

I want to increase the damage of all of my weapons by 50%, but I don't know which files contain the coding, or if the coding is a lot more difficult than something like: "TorpedoXdmg = 100" or something like that.
