Weapon Attack Power
How do the alien races get a beam weapon attack power rating on a small ship of 27? I've got advanced lasers IV researched and stoke 6 of them on a large hull and my beam attack power is only 6. The aliens can't have any more than 2 of them on a small ship. I even research heavily into miniaturization so I can cram more lasers on my ships. I'm talking in my territory, so they aren't getting a starbase assist bonus.
I've never been able to figure this out. Is it just because they have researched to the end of the beam tech tree? Or are there some other ways to get weapon power bonuses besides having a starbase nearby.
Thanks
