Any squids out their that can tell me just how our older and newer torpedos , work? 1> whats actually happening when you set the torpedo depth? 2> could a torpedo be launch when the outer doors are closed or even the inner door is open ? 3> are their any safety mechanisms for the firing and detonation ? 4> just how does a torpedo fire ? ( compress air, turbines driven, etc....) Just curious into how these things actually works.
