While I like the thought of an Exploration fleet, I think having several carriers AND a mega ship to supply might be putting too much onus on the expedition members in terms of time investment, especially when you consider that the carriers will be limited to their squadron members for delivery.
Little as I enjoy the fact, I don't live in that place and cannot devote my entire time to the needs of the expedition. Cat food and electricity must be earned.
Is that what we're suggesting? A megaship and a carrier?
