They are suppose to stun little ships and big ships alike not destroy them nessisarly

@Trotsky
I've to shoot 10 times a victory class to destroy it. And they gun doesn't even stun so what's the point?
It's so expensive compared to what it does

Yeah, the whole point of the gun is that it should be useful, right now its worthless to have. If its a balance worry do what a few other mods did which is jack up the price. If you want that ship killer gun, its okay to pay 20,000 for it.

I honestly do not see the underpowered aspect to it. One shot from one leaves my Praetors without shields and at about 75 or 80% health and if it is already engaged with a couple of Imperial or Imperial-IIs it really shifts the fight in favor of my enemy. I think the trick it to time it right with your other forces, its not meant to just be spammed constantly and win the battle on its own. Time it to when an enemy ship is engaged with one or two of yours and they will be much easier to pick off with your own forces.
