Hi, good steer for the 4000.
The biggest file is the naval base - ~5000 faces, the average is way less.
The P3C one of the most complex models at 5600, (and you need to lop off the props in meshlab )
Shipyard - only ~4400 faces, Seawolf ~4300 so most of these should work fine.
Meshlab can also perform a quadratic simplification of the faces to say the target 4000, so good as you say to target 4000 as a working target maximum, ta for the tip.
Just tried on the Seawolf and dropped it to 1500 faces and you can't tell - it actually looked better.
When using mesh-> filters -> remesh -> simplification it just drops the un-needed details mostly, we're after general shape not the exact number of vents etc.
Note that I am not going to post any of these works - happy to guide those who also have bought them - but Sonalyst's produced a great product and I am not going to betray them by distributing any of their work.
Where are you doing the simplification? (which program?)
To your point about sea levels - I believe the video below at ~27 secs shows the sea levels ?

Yeah, but the subs don't look like they are underwater at all, it looks like they are at periscope depth all the time, and the ocean doesn't look like the ocean.
I'm picky, I know :)
