Article talks about active sonar torpedoes. There were no such things in WW2. Passive only. The "cutie" http://www.bergall.org/cutie.html

Yeah I knew that, just figured it was a general question not just limited to the game. Nice link though. :up: In addition to Steam's fine info I imagine(Or at least hope) you checked out this link, http://www.navweaps.com/Weapons/WTUS_WWII.htm, above because it has a section refering the the Mk24 'fido' which was also a WWII passive homing torp...Theres a small section about the Mk27 but Steam's link fills in alot of info.
