Carrier oils provide the necessary lubrication to allow your hands to move freely over the skin and not cause skin friction while massaging and at the same time carry the essential oils into the body. One could disagree with any of these assumptions, but adding together modern communications, the lethality of ASMs and modern subs, and the ability of VLS tubes to partially substitute for defensive air cover, it makes a lot of sense to keep your carriers a few hundred miles apart.
In the fall of 2014, Carrier installed an innovative heating, ventilating and air-conditioning (HVAC) solution at the Sistine Chapel, specially developed to help preserve Michelangelo’s masterpieces against deterioration caused by an increasing number of visitors.
The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft can not launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket.
Now I have served in a 3 carrier strike formation and while it worked…we had a step learn curve and having several flag staffs hurt (same problem at BA and having a MEB staff in the space for MEU staff and having the other LHA/Ds have too much space for their command staffs).
In a peer war, the carrier group will be constantly on the move, fighting for its life every second, conducting ASW around the clock, darting into a launch position for a single strike and then retreating as fast as possible, operating under EMCON (to the extent that we even can anymore), maintaining a significant CAP 24/7, and so on. Nothing we’ve done has prepared any naval officer for this.
