Ok, if we are going to tweak things to get a more realistic and historical I thought it might be useful to compare and contrast ASW doctrine and development between the IJN and the Allies (RN, RCN and USN).
Here are two links to start:

REPORTS OF THE U.S. NAVAL TECHNICAL MISSION TO JAPAN
http://www.fischer-tropsch.org/prima...USNTMJ_toc.htm
We could look at:
1) Pre-war ASW doctrine
2) Wartime experience and development
3) Technology and weaponary
Just to start. Please add in your 2 cents.
