@SubmersedElk:
In a “search roll” scenario both players should independently roll to see if they detect the other. It should be possible for both sides to detect the other, not just the winner of a contested roll. One has to assume that both sides are using seaplane recon.
I agree. Also the soze of the airforce should be taken into account. Many BBs (and alot of smaller ships too) in WW2 had a few seaplanes They could fly around trying to find their enemy. Carriers however, would have a Much larger and more efficient unit/force of search planes. While landbased planes where much more limited by fuel and proximity to the coast.
I would rank it like this:
hunit, searchroll
DD: 2
Cr,BB, CV w/o planes, landbased ftr : 3
Landbased tac /Bomber : 4
Carrier with planes : 5
The best unit you have will determine your searchvalue.
