Question...mechanical malfuntions?

[AVGWarhawk]

SD/SJ malfunctioned quite a bit. In all reality, just a splash through the conning tower hatch and zap....tubes and wiring fried. Is there a way to mod this in the game? Reason I ask, the game does not allow you to use the radar in some subs because it was not available. Possibly find the trigger for that and have it set on a day off, perhaps a few hours, maybe the whole patrol? Perhaps have the game generate a failure via the damage control screen? Not sure. Can a mod be created that would generate a failure of a system? I suspect that is all that would be need because the game engine begins repairs when parts are damaged.
