No Bad has a good point.
In WWII esp later built carriers had a good turn of speed. The problem was the supply fleet, oilers, etc, tended to be slow, like 18 knots.
So Carrier captains had a choice to make, run fast, and risk being stuck someplace out of fuel till the tankers showed up.
Or run slow & keep your fuel supply's protected and your bunkers topped off regularly.
IMO all we really need to implement this is a speed control for the Carrier fleet.
Resupply ships would run the same waypoint, or try to follow the CV fleet.
It should also be able to rebuild the carrier somewhat faster.
Last, the game could use a lot more somewhat lightly defended maritime targets.
A couple of destroyers & 4 supply ships would fit that bill nicely!
