As far as I have been able to find out, a torpedo is attacked by all available turrets on a ship with a 10% chance for each to destroy it when it enters turret range.
That would mean that a torpedo entering range of a cruiser with 12 turrets would be destroyed around 70% of the time.
This does not seem to be the case during actual gameplay as far as I can tell.
Is there some hidden variable to the torps that isnt listed anywhere, or did I misunderstand how they work?
(9/10)^12 is the math I used to get the chance of the torpedo not getting destroyed.
