Yeah, the Typhoon sub was like two submarines side-by-side inside the external shell. The scene in the movie where Alec Baldwin fights the KGB agent between the missile silos ("Some things there don't react well to bullets") couldn't have happened as the missile tubes are between those internal hulls, though one could have argued this sub was built differently with it's "silent drive".

Still an amazing movie.
