Sorry, I think I wrote misunderstanding.
The point is that some realistic facts are not simulated, which are elemental in AntiASW tactics, like
-A DD cant ping me if my boat is located a specific maximum angle to his side/aft, because ASDIC, especially the early ones only had a narrow beam focus forward, so they had to turn the hole ship. In time, there were ASDICS mounted in swayable hulls to increase the efficiency. Also the beam itself got a bit brighter.
So a DD in 1940 cannot ping me while I'm with a WZB of 140°. The same counts for the hydro. If you run in a DDs aft, he can't hear you because of his ownship noise. This is simulated.
-The Escorts sensor efficiency (both ASDIC and Hydrophon) not seem to be shortened regardless my boat is within a hole convoy or on silent running. Its crazy to locate a submerged uboat running silent within a convoy with hydrophon.
-next the ASDIC seems to have no problems in spotting deep dived subs, but whith the first machines, the ASDIC searchhead was not able to be swayed vertically. Means the beam goes above the boat if its deep. 200m of course was deep for early WW2 ASDIC Systems.
I thinks its mostly a all or nothing principe if the spotting takes place or not, not concerning any currents or contingencies.
