A full 1:1 scale Delta IV-class nuclear submarine. All of my submarines are updated constantly, so expect updates to the project.
I built this submarine alone, no help from anyone else, and it took me around 3 1/2 days to complete from nothing to fully furnished interior.
This was my first ballistic missile (Boomer) submarine that I made 1:1 scale (166 blocks long) and I tried to make it very realistic looking, at least on the exterior.

I added a download link, enjoy!
