Well I don't know a lot about how the Jap DD's sonar worked but I guess that if the bottom was ideal conditions, it might be of some advantage as a last resort, to bottom it out (maybe the soft mud would absorb some of the sound???) but I don't think it would be to hard to ping out a big steel tube if the DD had a pretty good idea where it probably is.
If I remember right, Sailor Steve had a good post on this a while back.:hmm: Maybe we can dig it up or he could repost his thoughts.
