Take a look at the designs for the RN's new CVFs. You will see two separate islands, one forward for the fish heads and one aft for flyco.
We came up with this idea and the logic was debated back and forth within the design team and found to stand up. Basically, the fish heads preferred a forward position to see better when coming alongside and the Air Department requirements favoured a more aft position to afford a better view of the approach and landing. Questions about communicating between the two were answered by using electronic means and the ability to have an emergency ship driving position in the aft island and an emergency flyco in the forward one gave good redundancy in the event of a hit in the superstructure.
Aircraft carriers do indeed need superstructure above the flight deck; where else would you mount the various antennae? Or where would you fly an ensign to lower it so dramatically during cocktail parties??
I pitched the two islands idea to the Navy at a design review meeting and expected to be shot down in flames however they were completely content (taken in!!) and the ship design today still has two separate islands!
So, looks like the RN is not too slow to adopt new thinking after all!
Happy landings (or recoveries)
