60% eh? :hmm: Yes, of course, by no doubt it did make the uboats' task conciderably more difficult, but still, some got in, did the job and got out safe and sound, but HOW? The internet is full of pages describing page up and down about the wolf pack tactic and so on, but it is impossible to find anything anywhere on how the tactics changed later in the war, they must have changed. Regarding the shallow water, I never attack in shallow waters, this repeating situation was in the middle of the Atlantic with >1000 mtr. below the keel.

Yes, they have beefed up the DD sensors, which is realistic in my opinion because it would be possible to detect a sub at silent running with hydrophones and with asdic no matter how silent you are. But it just seems as if things like thermal layers, the limited scan cone of the asdic and so on have vanished, leaving the whole bloody Atlantic like a transparent roof
. :hmm: Maybe it's my computer, if it's at the low end of the processor/memory scale it might not be able to simulate all of that
