Revealing mistake: After Brashear surfaces with the re-captured nuke and it is being hoisted aboard, the mast line snaps and slices Brashear's leg. At the very moment the piece of metal cuts him, you can see the pant-leg switch from tan to white and back to tan.

Factual error: As it says at the very end of the movie, the year is 1969. In the near ending when Carl is in his room getting ready to go to the court hearing, which re-inlists him into the navy, if you look out his bedroom window there's a flag with 48 stars. In 1969 the flag was already 50 stars.
Mr. Pappy: Two tablespoons of machine oil can contaminate an entire ship's fresh water supply.
