I spent over 1 hour going through this stuff. F'ing cool
The attacks are not the best quality, but still give a great impression of what was going on. What was impressed on me was that the sailors in the recording were soo calm and business like--even though they were attacking two Japanese BB's. The tanker attack is pretty awesome also.
The training recordings for sonar opporators was pretty cool also. It's interesting hearing the actuall sounds that subs made--and the variety which they made.
Great link.
