From the IMDb
The submarine used in this movie was the USS Ronquil (SS-396). Her hull number was repainted to 509. The first nuclear powered United States Submarine was the USS Nautilus (SSN-571).
This (admittedly incomplete) list of U. S. submarines shows a gap in the numerical series surrounding "509" (which may have influenced the choice of the number since no "real" sub was identified in the movie).
