Also, there is no percentage indicator of hull damage, as in SHIII. You need to just be mindful of the type of damage you've received (bulkheads, flooding) and repaired and be cautious to the fact that it reflects some level of cumulative permanent damge to the strength/integrity of the boat.

I'd also suggest a Sargo class - you can start the war in a Sargo-clsss with twin 20mm Orlikins on the aft cigarette deck. SJ Radar is standard on all boats, but it is not run by the radar station in the boat (that will be for future SD Radar, when it becomes availabe for upgrading to). SJ radar is just there, and always on when surfaced - it is air search only. SJ Radar will warn you of unidedntified contacts coming in at very fast speed, which means an aircraft. Dive!! And go deep too - if you look at your boat from above the water on a clear day, you can often easily see it's shadow at periscope depth. Only slip to periscope depth, and you risk getting your 'scopes or worse damaged from concussion effect of bombs.
