I just ran across a convoy on my first patrol in '39... made three attack runs. I first discovered the convoy in the daytime, so I shadowed it until night fell. The first attack was made by getting ahead of the convoy (insanely easy, since it was doing 4 knots), submerging, and traveling on a course roughly perpendicular to the convoy's course at 1-3 knots. Running silent, of course. Second run was the same. Third run was the same, 'cept I switched sides so the moon would be behind me.
On the second and third runs, the front escort did get rather close to me, within a few thousand meters. It never heard me, nor saw my 'scope while I had it raised (a minute at the most).
Thing is, that was a destroyer, plain as day.
I've have major problems with the corvettes in NYGM2.* before... they seem to be able to find me precisely, and constantly stick with me for hours upon hours after finding me submerged. Destroyers, on the other hand, I've viewed depth charging spots kilometers away.
Makes me wonder if there's something to the corvettes that's been tweaked just a little bit too well...
