Seafloor's ASDIC protection

Matyas · 02-21-08, 09:15 AM

I'm currently in a dilemma. I have received a radio report about a convoy travelling along the eastern shores of Britain where the sea is quite shallow (30 meters at most) and I don't know whether it is worth the risk of engagment: if an escort picks me in such shallow water I'm dead meat as I can't escape their ASDIC by diving deep. (Also the low water pressure expands the lethal radius of DCs in theory, so they don't even have to be too precise to kill me.)

I faintly remember a story told by a German U-boat commander (maybe in Discovery channel): he said that their tactics in shallow water was coming to a full stop and lying down onto the seabed. That way they were undetectable to both hydrophones and ASDIC as they didn't make any noise and the sonic (echo) waves bouncing off the seabed created a lot of "noise" that hid them.

Does anyone have any idea about whether this phenomenon (i.e. the seafloor hides U-boat from ASDIC) is modeled in SH3? Knowing this would greatly help me doing my "risk analysis" before the attack.

BTW a second question: is the lethal (or effective) radius of DCs affected by depth (water pressure) in SH3? :hmm:
