I would have thought there are a few things to consider.
A aircraft carrier is for planes.
How do planes go up against drones?? Planes are more effective for attack rather than defence.
Furthermore US military can defend against missiles but how do they go defending against drone attacks on Israel??
The other thing is if the ships are in a similar location for a while theoretically they become vulnerable to a underwater attack and who knows what new technologies are possible?
There must be a reason Israel is attacking Gaza and is US looking to create a new base there?? Would not surprise me if they were in terms of long term expansion plans like they have in other areas of the world.
Use of drones is changing the dynamic of warfare, some old ways no doubt will have become less effective in certain scenarios
