Erm.....because the Captain of a ship has, ideally, some knowledge of how to drive a ship. And a Carrier is never someones first floating command, thus making it somewhat tricky to fit in the required experience for a Crab?
Not at all. The Captain of a ship doesn't have to know how to drive it. he would have a team of Navigators for that...
The Captain of a Frigate / Destroyer is the Authorising Officer for the organic aircrafts flying and yet he isn't an aviator.
An Aircraft carrier is essentially a floating air base right therefore logically the Captain of the carrier would be the same rank as a Base commander yes? then surely the senior man involved in air ops on the base would be subordonate to the base commander?
The CVF isn't just a floating air base. its the lead ship of a Carrier Battle Group.
Such as this (Although, we will never be able to muster any where near that size of CBG.) Be aware that there will also be 2 or 3 vessels in that Group which you cannot see at the moment.
