Corrected entry: Throughout the entire movie, Denzel Washington as XO says his rank is Lieutenant Commander. He is also spoken to as Lieutenant Commander by the Rear Admiral of the convening board. however his shoulder boards on his uniform at the final trial indicate he is a Commander, not a Lieutenant Commander.
Corrected entry: SSBN's (boomers) are too valuable to go out on patrol alone. They are ALWAYS accompanied by an attack sub whose job it is to "sanitize" the boomer's area of operation of unfriendly subs.
Corrected entry: No XO of any submarine would EVER don fire fighting gear and go fight a galley fire as portrayed. This can't be explained away as a 'character decision'. It is simply inconceivable that an experienced XO like Hunter would personally tackle a galley fire. On board a sub there is a dedicated fire fighting team made up of members of the boat's crew. The XO's place is on the bridge or emergency control centre as it is his job to co-ordinate the fire fighting effort. This is partly due to the fact that as the XO he may be required to attend to other situations that could arise (which is EXACTLY what happens in the movie). Hunter was actually in serious breach of protocol/ regulations by risking his life fighting the fire himself. Though it may seem bizarre to civilians, Hunter would in reality face much graver consequences for doing this than he would for anything else he does in the movie.
Corrected entry: After the first torpedo attack, it is explained to the XO that the last EAM was cut off when the radio buoy's cable was severed in the attack. An outside shot shows the rear of the sub traveling forward away from camera, with the frayed cable trailing from the top of the sub's hull at a slightly upward angle, and running beyond the rudder. In fact, what should really happen in the shot, is the cable will follow the surface of the hull because the flow of water around the sub would force it to. That would put the cable right into the propeller and cause all sorts of mayhem. This mistake could have been easily avoided by simply having had the cable cut shorter in the attack. (00:55:05)
Corrected entry: The cook who was killed is well beyond the Navy's weight standards. He should never have been on the boat to begin with.
Corrected entry: In one scene Denzel Washington says that the last time American went to DEFCON three was during the Cuban Missile Crisis (which occurred in 1962). They apparently didn't look far enough forward in the history books. In October 1973 when Egyptian and Syrian forces launched a surprise attack on Israel, America upgraded to DEFCON three because of fears that the Soviets may also intervene.
Corrected entry: In submarine movies the interior set is normally larger than life, to allow the movement of crew and equipment. But in Crimson Tide, the Alabama is WAY to big on the inside. In real life, the captain can stand by the periscope and tap the diving officer on the shoulder without moving his feet, whereas Gene Hackman had to walk a great distance to talk to George Dzundza.
Corrected entry: In the scene where Gene Hackman regains command of the Alabama, he tells his loyal officers to inform their men personally that he is again in command of the ship. As soon as they turn around to go back to their stations, Gene Hackman picks up the intercom and tells the entire ship that he is again in command. So why did he want his men to do it, if he was going to do it himself?
Corrected entry: When the men are attempting to repair the radio, one of the men is talking on a Navy phone set which requires you to push in a button on the handset. He is pushing in the button in most scenes but in one particular scene he is holding handset between his shoulder and ear while working with both hands.
Corrected entry: At one point a character sneaks through the bowels of the ship from one end to the other. This would be hard to do since he would have to pass through the lower level reactor compartment. Even if you could do this (there is no such passage on any nuclear sub) it would not be very healthy.
Corrected entry: U.S. Submariners do not salute underway because military protocol stipulates that saluting does not occur indoors.
Corrected entry: In one scene, Captain Ramsey threatens to shoot Weaps if he doesn't open the safe that contains the tactical firing trigger. Then he says it does him no good to kill Weaps, as he's the only one who knows the combination to the safe. It is unlikely that only one person knows the combination: what if that person had died in the galley fire or drowned in the bilge bay? The crew is left with a safe that can't be opened.
Corrected entry: There is no way a dog would ever be allowed on a US nuclear sub and would definitely not be allowed to relieve itself in one of the main areas. I know quite a few men in the Navy who are not very fond of that.
Corrected entry: Using 10 nukes (at least) to destroy a base seems a tremendous overkill. A couple of standard missiles or bombs would do the job perfectly.
Corrected entry: the Alabama is shown diving underwater with a long cable attached in two scenes, long before the scene of the launch of radio beacon happens (when winch cable gets cut and cable remains dangling...)
