Hey there...
I found this website on Kursk...it has some photos and a bit of information.

Additionally, I read a review of the model you're building on Kursk...
The builder suggested the kit was a bit basic and lacked detail...but that seems
common for many sub models even with manufacturers who are supposed
to put out good kits...
Maybe you should try building one of those cut away hull subs if it's details
you're looking for.
I know Revell makes a couple of a U-boat and an American sub...There's
also one on the Andrew Jackson a Polaris boat if i'm not mistaken...
Check www.tridenthobbies.com or www.pacific-fronthobbies.com if you'd
like for those and other subs...
Sorry for the disappointment but with a bunch of good painting and a few
aftermarket things maybe she might be seaworthy after all.
If I come across the review or anything else i'll send it to you.
Take Care,
Tank
