Okay, this is very confusing at the moment.

This is my first B model, which is designed for the most part to be very safe and secure as a design. You will notice that it's built with armor behind parts of the newly installed guns and so on. The issue with it at the moment, is that I was worried about running out of batteries too soon, or having to take forever to reload weapons, or trying to cut costs.

This is the B1 model, which has close enough to ten bouts with the B and B2 models. It's designed to cut costs, increase battery storage, and seriously increase firerate. The problem is that if you take out one of the guns, the ammo behind it can easily go up too, and then everything is on fire.
I obviously need to put fire extinguishers in these things. Right now I'm testing without them.
I found that the B model typically won as it was safer, but if the B1 model focused on taking out the gun and then the ammo factory behind it, everything would explode or be on fire.

The B2 model was designed to fix that problem, increase firerate, and be generally safer more or less. It performs a lot better, but it still struggles with firing very slowly and costing more than the B1 model.
At the moment I am at a loss as to what model to test with next, or which model to choose. I'm either making the ship not safe enough, or making it cost too much while firing too slowly. I could switch over to mod weapons, but I wanted to take a crack at it without mods first.
