OK, I take it you didn't read.
Battleship Theory details that there is no point in making smaller ships - ships must constantly get bigger to use larger and more apocalyptic weapons. It's like... a Paragon using plasma cannons on it's two large turrets against a Wolf. The wolf dies nigh instantaneously, right? That's EXACTLY the problem that Battleship Theory points out. So, ships get bigger, and bigger, and bigger... the cycle repeats forever...
Battleship theory is outdated even in our time today, what makes you think it holds water in the future, or space.
Carriers are the thing today, actual have bin for a while. Still means nothing in space.
Actually Orbital Strike Platforms are being developed today, that's the new arms race going on right now in the world. But again, that means nothing in space. Funny enough.
Nooo... my Mjolnir Cannons...

You do realize you need something to lead an electrical charge throe right? Space. Vacuum of space. Give it a moment of thought.
