Fair enough. I get your point about volume really mattering only to the extent that one has to protect it. I had wondered a bit about the cost of moving weapons further away from the reactor. But, unless the power "cables" (for lack of a better term) are really mass intensive, bracing a turret is probably a far more significant concern. And concentrating too much recoil in one spot probably has its own issues.fractalsponge1 wrote: Weapons - partly it's style and based on existing references. But if it's up to me I like centerline mounts because they have the best arc, but the ability to mount many of them is limiting. The result go to flanks and then I just I try to give them the best arc possible given the hull form.

For design trade offs, I think the key thing to look at is mass, not volume, because that determines what's required for good acceleration. Armor is expensive in that it is heavy (neutronium), weapons are heavy for the structural strength necessary to take continent-evaporating recoil (probably also something involving neutronium). I happen to think SW warships use very little power relatively speaking for propulsion - most of it is going to weapons or shields. If a significant portion of SW power is needed to move their mass, that mass is so great that some canon scenes of ships interacting with planets become impossibly mild in terms of effects (the Lucrehulk crashing in AOTC, for example).

[W]arships need protected volume, so engines that get big cost armor. At that point, weapons and their recoil absorbing structure is the only thing to give.
Centerline turrets certainly make sense to me. And, I do prefer the look. Centerline always seems neater and more "professional," in the same way that two turrets fore and aft always looks "right."
Edit: I appreciate your point about the Star Destroyer occupying a sweet spot. Does explain 25,000 and counting. As I say, part of what I am really enjoy with these recent frigates is that the hulls are large enough to allow some nice toys, but small enough that one has to balance - and decide what one gives up relative to an ISD. The balance of protection, mobility, and firepower (with the implicit issue of endurance in each case).
