Planes are starting to annoy me

[Red Devil]

Point taken about the subs on surface in daylight. If we wanted to be 100% historical then yes, but when I find a convoy, I would rather it be with fully loaded batteries and not possibly half dead or worse. It happened to me the once, loaded with full trops but only 10% battery left and a bloody large convoy in my earphones but could not surface to do an end around attack. At least with a full battery pack, I could have withdrawn at speed, surfaced out of site, and ran like hell for a decent intercept point. I supose its all a question of how accurate you want it to be?

Submarines were always intended as a surfaced fighter with the ability to dive out of harms way; at least the was the WW1 conception of a U Boat. This was still the "norm" at the beginning of WW2.
