Deliberate mistake: During the part of the movie where the USS Alabama is sinking deeper into the ocean a shot of the depth gauge was made showing the sub passing 1800 feet at a quick rate. About 20-30 seconds of shots were shown after this to further dramatize the peril of submarine and then the scene cut back to the depth gauge. This time however, the gauge was moving much slower and only shown the sub had sunk 15-20 more feet without any reason for the sudden slowdown in decent.

Plot hole: Throughout the movie an incoming EAM must go through an authentication process prior to it being considered valid. The crew failed to do this on the second EAM of the movie that set DEFCON 3.
