Not all submarines have to have a periscope to define as one. Heck some submarines don't even have one. And it doesn't matter what type of propulsion it has as long as it can power itself. Gas, diesel, nuclear, even hand cranked.
Of course! it seems that you didn't get my point!
there are lots of submarines that lack one of the factors that I mentioned! but when a maritime vehicle lacks all of them (!) it sure isn't a submarine!
