Torpedos require a 300 meter running distance before they arm (to prevent them from blowing up and damaging the sub). Sometimes you can get away with a magnetic torpedo at less than 300 meters, but not much less, so it's better to play it safe. Firing between 500 and 1000 meters gives good results and plenty of room to spare. You can sink small boats with the flak gun but it's not very useful against larger ships.
Good luck and welcome to the forum!
