Civilian-operated cargo subs do exist but are not utilised in exactly the manner I think you are suggesting... as in, there have been several cases I have seen news reports about which involved the detection and seizure of submersibles and semi-submersibles being used to smuggle drugs (cocaine into the US IIRC).
