Torpedo Bug?

[ediko]

Try switching to magnetics. Impact torpedoes need to hit the target at almost perfect 90 degrees. Magnetics can and most of the times will detonate at any angle but the most steepest. Also if you use magnetics they might deflect from the curved surface at the bottom of the ship so aim a bit lower with them so the torpedo goes under the ship, or a bit higher so it should definitely hit. And dud's happen. I had all 4 of my torpedoes fail me like that when attacking convoys so don't worry. Real Kaleuns had it even worse than we do right now

EDIT.

Just now saw that you don't know what pistols are. Pistol is located at the front of the torpedo. It is it's nose. Now there are 2 types of them- impact and magnetic. Impact only work properly when they hit the ship physically and at a good angle. Magnetics on the other hand explode when they are close to a ship. When a magnetic is close to metal witchcraft happens and they explode a bit sooner before hitting the ship. Very useful for sending your torpedoes just a meter under the ship so they sense it and explode beneath it causing severe flooding, disastrous damage and even splitting the ship in two if you're lucky and hit a good spot. Hope that cleared it up a little. You can switch them in the F6 view on the top right corner IIRC. If anything else just ask.
