When I was in the Navy the sub guys told us the only ones that ever had a chance of finding our SSBN's were our own attack boats and even that was rare. My first ship was a guided missile destroyer. Only thing our active sonar was good for was messing with whales!

Soviet nukes in the old days were notoriously noisy....I don't know about the new ones. That said, if true about the P-3s (and I have reason for skepticism), there may have been other reasons for that success that may still be classified, so I'm reluctant to mention them. Diesel boats are another story. But your active sonar wasn't just good for messing with whales, it would be a big help to any sub wanting a good fire control solution before releasing torpedoes.
All that said, the first problem is determining a sub is in the general area as opposed to somewhere in the ocean. This probably isn't the place to get into anti-sub warfare ops and I'm probably not current anyway. But I think everyone can agree that it's going to be a lot easier to detect a big ship on the surface than a submarine, since you can actually see ships on the surface. And once detected they're also going to be easier to hit. A surface battle against the Ruskies or Chicoms isn't going to be like the gun duels of WW2. The British experience in the Falklands should have been instructive but so far as I can tell seeing the "Littoral" ships being produced these days, it wasn't.
