There are some differences between an impact torpedo attack vs a magnetic one, With impact torpedoes you idealy want to be shooting at around 90 degrees AoB (from the side of the target) to give your torpedos the best chance of hitting something flat so they will detonate. Should i set up my attack differently when using impact vs magnetic? Instead i usualy set the torpedo to impact running 2-3m deep. Though i will say that when the sea is realy rough (12 or better m/s wind) i usualy dont attempt magnetic shots as the ship's actual depth varries too much which will cause magnetics to either run under too deep, or bounce off the keel as much as they would detonate. The rule of thumb i usualy use is 0.5m deeper then the ship's draft for clear weather (0-5m/s windspeed) 1m for moderate seas (5-10m/s wind) and 2m for heavy sea states. Well this depends on 2 factors, the draft of the ship, and the weather. What is the best depth to use for magnetic torpedos? With magnetic torpedos in stormy weather you can sometimes have the ship pitch down due to waves and have the torpedo bounce off the keel. Also occasionaly you will run into dud torpedoes. Keep in mind that ships are not box shaped under water, they curve in many places, towards the rudder, and underneath towards the keel. Second for impact or impact/magnetic torpedoes (Torpedoes set to magnetic can still act as impact torpedoes) the torpedo head needs to strike a flat surface nearly head on to detonate (roughly between 70-120 degees), also this applies in the vertical as well as horrizontal, if the slope is too shallow the torpedo will bounce every time. Well a couple of possible reasons, first your torpedo needs to travel a absolute minimum of 250 meters to arm itself (good rule of thumb is never shoot closer then 300m). Why do my torpedos keep bouncing off the ship?
