Spaceships: Optional Equipment and Crewing
1. It just occurred to me, a lot of our vessels may be undermanned.
2. I don't see the manning requirements for a lot of optional equipment, such as launch tubes.
3. It's quite possible to have crew being able to maintain and/or operate such equipment, as well as whatever is their primary job.
4. For gunnery, I rather doubt that the tonnage discounts works, since if you can batteryize any number of weapon systems through the reduction of gunners at a hundred kilotonnes, you can do that at one kilotonne.
5. Hard to say about auxiliary 'craft: could be more based on the actual usage, rather than just tonnage.
6. Engineering should be based on the actual cohesive volume of the drives and power plants, since it would make no difference in supervision, regardless of the hull volume.
