As I explained before, this weapon is a ship's main cannon. it is not a secondary weapon, but rather a large, powerful, primary cannon. I designed it to fit in the SDR 4 category, so that's where it should go.
If the design as it stands cannot make it in that category, then, please, could you be helpful and make a suggestion as to how it can work as a Primary weapon?
I am asking for comments and suggestions not one sentence answers that tell me absolutely nothing.
