Engine position below com, bow profile looks like it'll try to push itself out of the water, ballast tanks what are those? And they want 50kph submerged?

The dinky torpedoes are cute I suppose.

With these wings they are probably using negative hydrodynamic lift to stay underwater?

If that's the plan the current design looks far too rigid, they'd need to adjust their cruising speed based on payload to ensure consistent depth keeping. How would they lurk without floating up?

Well – they'd have to lurk like loitering munition – cruising.

I think it looks far more like an ekranoplane than a submersible craft. The 10 passenger + 1 pilot capacity is interesting in that context: according to the source of all wisdom and knowledge, the international rules for ground effect vehicles apply only to crafts carrying 12 passengers and more.

If they have to constantly be moving then that dramatically shortens their mission time and sacrifices stealth.
