Why the heck does it take 391 sailors for that thing?
So, between propulsion, comms, weapons, navigation, aviation (it can handle a couple of Sea Stallions), cargo handling, well deck handling for the LCACs or other landing craft, the food, laundry, watches, the medical facilities on the ship and doing all of that and more for 24 X 7...it all adds up.
How many do you think it should take?
