2. The akulas didnt have the UUV before the fix
3. Yes I notice that to. Too sensitive in my opinion, but I dont know anyting about UUV so...
5. You probably are aware of this but you cant change the depth of an active torpedo, you have to shut down the active sonar first (preenable) and then change the depth.
6. I think that is supposed to work like that. Here is form the RAweapmanual:
If the device is launched on cruise speed of 4 knots or less, passive sonar will begin returns
immediately (as the speed is within the limits of 4 kts and less). At activation of the button
ENABLE, will begin to work active sonar
