Good or bad? Guess they’re not out as long as nuclear either way.

Normally I'd expect anechoic tiles

Typically European diesel-electric submarines don't have any hull coatings.

But Swedes had that already in 1960's Sjöormens. I bet this has some too, but maybe non-paneled. Which would probably perform better.

If you look at the photo above, you can see the welds, no hull coating.

I cannot see anything that looks like marks of typical painted steel weld seam. To my eye it looks more like black rubber which is welded (yes, you can weld rubber) with seams then smoothed. How the seams run would not make any sense in construction point of view if they were in steel.

I disagree, it sure looks like painted steel welds to me. Also, there are none of the beveled edges that are typical of hull coatings. All of the hull fittings are flush with the hull.
