Oh, you were talking about cost efficiency, while I thought of base cost. Sorry for any misunderstanding. (Although the increase in damage given by the Heavy and Massive Mounts isn't that great compared to a Large Mount, it does exist.) As for increased damage resistance, it might be a curse as well as it makes these weapons more vulnerable. But having one or two hundred more hitpoints isn't going to matter if your ship is destroyed in a single volley, nor will it be a problem if the weapons are shut down before all other components.

Using a given hull size is a whole different topic, and one that has been heavily discussed I gather. My concern was not about using bigger ships (say, a Battleship), but rather about the usefulness of using Heavy Mounts compared to the previous Large Mounts, available for all warships starting from the Light Cruiser. (Can you guess I am biased against the Massive Mount, and so the Baseships?) And of course, my problem was to determine whether a +12,5% increase in damage per kt was worth the increased vulnerability of the weapon systems. I am now minded to believe it is, mainly because it doesn't cost anything to use Heavy Mounts instead of Large Mounts, and skirmishes aren't exactly frequent.

*Grumbles* I should really get back to working on something besides my scheming efforts.
