Just so you know peabody. for a quick test, just chuck the american torpedo linkname on a plane and you will see the plane drops them.
The reason it MAY be worth testing on a ship like bismark, is because it is much longer than a submarine. For example, if the plane aims at the centre of the bismark, more of the forward area will cross the torpedo's path than a sumbarines would. BUT, if the planes miss a few time, you know not to waste time modifying thing to make it work. It either will or it won't
The one thing that will look cool in that scenario, is torpedo planes do not come in from height... they fly in VERY low. You can set them as low as 20 metres and no crashes. They also come in low from a long range, meaning you dont see them drop from the sky like other aircraft.
