Yeah, you are proabaly right SubSerpent. German U-Boats were small indeed. I just was fondly remembering the towed array from my 688 Attack Sub days!
Actually the Germans did come up with a towed array of sorts. I am sure you have heard of the
Bachstelze. A towed array for the air, not the sea.

This would be a fun toy in SHIII wouldn't it! I don't know about losing a crewman every time I crash dive though. WAIT A MINUTE! That would be a great place to station seaman BERNARD!
