Show truth in 3D only?

However, when you surface, you should get visual contacts, which you don't on sub (AFAIK). That's a bug.

In the database, subs do not have a "lookout sensor" assigned, unlike surface platforms, so there will be no automatic reporting of contacts from the sail bridge.

I'm not sure if this is "realistic" or not, as the FFG, for example, has a lookout sensor, but also has a whole team on board dedicated to the watch station. Why would you ever be on the surface looking around anyway??? Unless you were poping off a manpad...
