You've asked this question before, so I'll refer you to the answer I gave then.
Apart from a Gato class (and this a hull set only), there is very little WWII stuff in 1/96th scale, because this gives you a very small and fiddly boat to model, and most folk want something a bit bigger and tougher.
Bear in mind that subs tend to get a rough time when compared with surface ships. Fine detail is easily knocked off, even on the larger scales.
There is a lot of stuff available at 1/144th scale, but that is aimed at the static modellers, although some folk like to have a crack at converting them to RC, which is entirely possible with todays miniature equipment.
