Or a scenario that would test the most patient player. If a surfaced sub could be made to dive when threatened, a heavy, low flying bomber with radar could search for subs, while radar-equipped JU-88s out of Lorient search for the bomber. If cargo ships could be triggered to die when a sub is in the area, then everyone has a cat-and-mouse mission. Maybe throw in some radar-equipped stringbags flying off a navigable Bogue-class "jeep" carrier, itself subject to sinking, bobbing in the seas so severely that even the strinbag is a handful.
Add a little fog or poor light and, bingo, sheer madness.
I want a Dunkeswell/Lorient chess game
