But i remember someone telling me that German subs could dive deeper than their US counterparts because they were smaller and displaced less water or something. lol

Well, to add a little more to Sailor Steve's remarks :up: (see above post), there was an added factor as to why the Germans went so deep in their subs. Basically--they had to. The Allied sonar changes, starting with Q apparatus and culminating in Type 147 Sword sonar gave the allies the ability to look down at much greater angles than the Japanese ever could. A U-Boat at 300 feet was in perfect hedge-hog range for a 147 equipped escort where a Japanese escort would lose contact with a boat that deep while still ~400-500 yards away.
The Americans did go deep to--usually by accident. the Tang went to 700 feet and survived. Test depth was 400 (Balao). The Puffer sweated out an attack for 37 hours at 500 feet (Gato Class--300' test depth). Even the old Pollock had it's 500+ foot moment, twice it's test depth!
In Peter Cremer's excellent book U-Boat Commander, he tells about how they took their boats down until the "frame members began to crack". And they still got the poop kicked out of them.
"Have To" was a great motivator for the depths gone to by the Germans in WWII...
Cheers!
