Crude Aircraft Carriers and Sea Aerodrome

I dont care if it's a super late game feature that's ungodly expensive to produce. I think we should have mobile aerodromes in the water to create new routes for airplanes. The navy would obviously need to defend these new units as they should be very squishy. I'm even down to restrict them to only fighters. This would allow the player to move fighters around in ways they simply cannot due to their range of motion.
