I am an ex-Navy Nuke submariner (USS Pintado SSN-672 '87-90), and US subs - including WW2 fleet boats normally surfaced without air. When submerged, boats are normally trimmed to have a slightly negative buoyancy (so going to all stop to preserve the batteries isn't realistic either). Just prior to surfacing, the order "Prepare to surface without air" is given and the boat is driven to the surface with propulsion. At this point, the main deck is awash and the shortly thereafter, the Low Pressure Blower is started which blows the remaining water out of the ballast tanks. My reading indicates our WW2 fleet boats surfaced the same way - I believe, the LP Blower in those days was called the Turbo Blower. If memory serves, it took Pintado 10-20 minutes to reach a normal surface running trim after the LP Blower was started.
Just my 2 cents here.

Thanks for the information, I have only been driving these virtual subs for about a year and I always wondered about the Dive/Surface abilities. Now I have a better picture!

Who knows how our sim is coded in replicating this dive/surface activity.

Thanks
