Well, the hint about recently released photo-etched parts tipped me off. This is the Nautilus, from Jules Verne's 20,000 Leagues Under the Sea. The basic kit is made by Pegasus Models; it and the photo-etched set are listed by Freetime Hobbies.
I've seen quite a few models of this fictitious submarine over the years. The only thing that makes me raise my eyebrows a little bit is that all the kits I've seen have been based (more or less) on the ship in the Disney movie. It's a fun movie (where else can you hear Kirk Douglas sing?), but the ship is the invention of the Disney designers - not Jules Verne.
Quite a few years ago the Naval Institute Press published a beautiful edition of 20,000 Leagues Under the Sea, with superb reproductions of the engravings that appeared in the original edition (or one published shortly thereafter - while Verne was alive). The pictures show the Nautilus as a very simple shape - more-or-less a cylinder with pointed ends. The text of the book describes something similar.
What we're talking about here, of course, is a completely fictitious subject, so no normal criteria of accuracy really apply. And the Pegasus version certainly isn't identical to the ship in the movie; it looks like the kit designers added a good deal from their own imaginations. The modeler surely ought to feel give his/her imagination free rein on a project like this. I do think, though, that it's appropriate to acknowledge the genius of the Disney people alongside the genius of Jules Verne.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
