Some more tips when sailing the Oyodo.
Keep your speed below 25knts when searching for subs.
Only use OH to get out off danger. When OH is used sonar needs recovery time.
Time your HH, Oyodo only have 4 launchers it can shoot at once.
Stay close to the BB line but give the BB´s room to do there fighting.
Check for enemy Fps before you lauch your Tbs.
Lower your Tbs hight as soon you dropped off your torpdo's to keep them save from enemy AA, it also make them land faster on your ship when they are at zero attitude.
To blind torpbomb a submarine keep in mind that most Submarine Cpts dont change course when they dived, I use my mouse pointer to track the submarine when it dives.
When your Tbs sudenly seems to lose AAW resistens replace your sonarman on a other support slot. ( this is a bug, much more notible when using a IJN Tb Submarine )
3 Tbs to sink a white bar submarine.
4 Tbs to sink a 1 gold bar submarine.
5 or more Tbs to sink anything better.
