The Submarines survived by surfacing at night and recharging their batteries when it was safe to run those diesel engines.
I don't think a stealth ship should have an icon for everyone to see. WWII subs were slow and it will take forever for them
to go anywhere. Leave the icons off or some bombster is gonna get 'em.
<S> Skyguns.....you obviously put allot of effort in your post.
Maybe as previously posted....to keep it simple, the sub commanders only see the control room and when at periscope depth
they can pan around and observe the surface ships, ect. Out the portholes......you gotta see a mermaid occasionally

btw.....where is that pesky Nemo anyway?
Mine mine mine mine mine mine mine ! ! ! ! ! ! ! ! !
