Well, I built this (this is one of my earlier designs, as I don't currently have access to my later ones, but the main ION beam is pretty much is the same) I designed it to be the most powerful single beam ship possible using the normal grid size. My later designs include some actual defensive armoring, except on the rear, and engines, additional weapons, etc. (But I am on the wrong computer for that) But this beam is designed for the maximum efficiency of damage compared to the number of ion beams. (Though I have since found that 100 uncombined ion beams are far more powerful, once they are all targeting a singular spot)
