Having a little expertise in some of the promises, I thought I'd have a look. But the whole article reads like a procurement wish/pitch, not even specs yet.

There's no peer reviewed physical way they can achieve some of the claims, and doubtful if it's possible at all within current understanding of physics.

I'm happy to be contradicted though, it's about time we had a new understanding of physics, Quantum mechanics is over a century old now.

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.
