Factual errors: Numerous violations of standard Navy operating procedures.
Incorrectly regarded as goofs: Naval officers were formerly allowed to use umbrellas only if they were being held by someone else. However, this rule has been changed.
Factual errors: Several shots of the USS Alabama are not of a Trident (Ohio Class) submarine, rather a 688 (Los Angeles class) fast attack submarine.
Factual errors: If the Alabama were sent into as tense a situation as depicted in the movie she would have been escorted by a fast attack sub. Hence, the confrontation with the Akula would have been handled by an accompanying Los Angeles/Seawolf/Virginia class boat while the Alabama would escape to launch her missiles.
Factual errors: Capt. Ramsey gives the missile launch keys to only one crewman. Proper procedure is to have two crewmen receive and deliver the keys to launch control together.
Factual errors: Boomers have two requirements while out on patrol: remain undetected and maintain communications. They carry as many radios as they do missiles. There is ALWAYS a backup should one fail.
Continuity: The orientation of the oncoming torpedoes is always the same when shown on the sonar scope, yet the crew indicate that the torpedoes' course has changed drastically.
Incorrectly regarded as goofs: Smoking is (or at least was, at the time of this movie) permitted on U.S. submarines.
Factual errors: The sonar is not displayed in the "radar" manner that is depicted in the movie. Actual sonar uses what is a called a "waterfall" display, so called because it shows the different sound frequencies on a vertical display that moves from the top down. One of these displays is shown very briefly at the first moment of contact with the Akula.
Factual errors: On 26 October, when Hunter briefs the officers after receipt of the first EAM placing forces at Defcon 3, he states the last time forces were at that level of readiness was during the Cuban Missile Crisis, "32 1/2 years ago". The Cuban Missile Crisis was ALSO in October, so no matter what year in which this film was set, there would be no half year involved. And, anyway, it was last ordered in 1973, during the Arab-Israeli War.
Factual errors: The XO is informed that the fire in the galley could not be extinguished because "the switch was too hot". The galley is equipped with an APC (aqueous potassium carbonate) system for galley fires. It can be activated by pulling a ring next to the equipment, which is probably what they were talking about. However, there is also a remote activation switch outside the compartment and also the system is equipped with a fuse that melts at 400 degrees and automatically initiates the system. Since it was "too hot", the fire probably would have been put out long before the XO showed up. Either way, no one would have to go anywhere near the fire to extinguish it.
Factual errors: The XO, Hunter, gives the order to fire torpedo tubes 2 and 4; the next shot shows two forward starboard doors open; the subsequent shot shows torpedoes firing from opposite sides of the boat. On all U.S. Navy submarines, torpedo tubes 2 and 4 are located on the same side.
Continuity: During the Alabama's dive, she is seen with her periscope deployed on the surface, with decks awash. There is a cut to an underwater shot from above, that shows her sail with all periscopes retracted, and their doors closed. In the next shot, the boat is fully submerged, with its scope deployed and visible cutting through the water.
Continuity: When Hunter and Ramsey are on the bridge of the sail, the sub is rolling significantly with the swell. The next shot is of a relatively calm sea with the sub ploughing through it with no roll.
Miscellaneous: On the cover of the unrated extended version the submarine appears to be the USS Silversides (SS-236), a WWII-era sub launched in 1941, and not the USS Alabama (SSBN-731).
Factual errors: When Ramsey reads Hunter's Record, after he has been removed from command, the last entry says Hunter was stationed as Lt. Commander on the USS Alaska SSBN-723. The USS Alaska is SSBN-732 not 723.
Factual errors: When the CO is meeting the XO he notes that he has made patrols on fast attacks and boomers. Fast attack submarines do not make "patrols." They are called deployments or missions. Fast attack submarine only make patrols in wartime situations.
Factual errors: There are several incidents of mis-use of sound powered phones, including a chest set being used for a 1MC. Vossler speaks into the phone without pressing the talk button.
Plot holes: Several times throughout the film, the importance of launching their missiles before the Russian missiles have been fueled is stressed. But in reality, they would have had to launch the missiles well in advance of that deadline in order to strike their targets before the Russian missiles could be launched, otherwise the missiles would simply pass each other in the air.
Factual errors: During the galley fire the General Alarm would have been sounded and the crew would all have to don EAB's (Emergency Air Breathing) masks, yet none were worn.
Factual errors: During Battle Stations, senior enlisted and junior officers would man the sensor systems (i.e Sonar, ESM) yet the Sonar Supervisor was a junior enlisted man.
Errors made by characters (possibly deliberate errors by the filmmakers): The sub commander in "Run Silent, Run Deep" is Clark Gable, not Cary Grant.
Revealing mistakes: During the opening news report aboard the French carrier Foch, the reporter states that "these French planes are being readied...", but the very next image shows three U.S. F-14 Tomcats flying in a V-formation.
Factual errors: Ohio-class SSBNs have no compartment called bilge bay. Also, there are no strobing yellow lights, nor are the missile decks made of see through grated decking, and there are no "crawl spaces" that would allow free clandestine movement around the boat.
Errors made by characters (possibly deliberate errors by the filmmakers): When Captain Ramsey reads the EAM to Hunter, he says "Rebel Controled Missiles Being fueled, Launch Codes compromised". However, the EAM clearly states "Russian Missiles being Fueled, Ready to Launch in one hour".
Factual errors: The Chief of the Boat is an enlisted man. In this film the Chief of the Boat is wearing a hat with a gold chin strap. Only officers' hats have gold chin straps. Enlisted men's chin straps are black.
Factual errors: When the Captain conducts his first interview of his new executive officer (XO), the Chief of the Boat is present. This is highly irregular and unlikely to occur because the Chief of the Boat is an enlisted man. As a subordinate to the XO, the Chief of the Boat's presence during this interview is improper and violates protocol.
Factual errors: Nuclear weapons are only authorized when readiness is at DEFCON 1, not 2.
Errors made by characters (possibly deliberate errors by the filmmakers): On the bus prior to departing for the sub, the character Lt. Dougherty barks at a sailor for failing to address him as sir and orders him to stand at attention. While this is not inappropriate, ordering him to drop and do push ups certainly is. Superior officers are not permitted to arbitrarily punish subordinates with physical exercise as a basic training drill instructor would. This is considered abusive treatment and the subordinate is not obligated to obey. Further, the officer can be brought up on charges.
Crew or equipment visible: Reflected in the mirror on the door of Hunter's stateroom when COB shuts the door leaving.
Factual errors: In a mutiny/stand-off scene Capt. Frank Ramsey tells Lt. Commander Ron Hunter about Lipizzaner horses; how those are "all white" and "from Portugal". Hunter corrects Ramsey with that the horses are from Spain and that those "are born black". Ramsey insists that they are from Portugal. At the very end scene, Ramsey volunteers to Hunter that Hunter is right; the horses are from Spain. However - both are wrong: The horses are nowadays bred in Austria, but originally in the town of Lipizza in Slovenia (hence the name). The Spain confusion is probably due to that the horses are trained by riders from the Spanish Riding School in Vienna, Austria, established in 1572. The colour issue? A Lippizaner is born black but turn white when reaching maturity.
Errors made by characters (possibly deliberate errors by the filmmakers): Several characters, especially Captain Ramsey, refer to the submarine as a "ship." Traditionally, a submarine is referred to as a "boat," with the term "ship" being reserved for vessels that travel on the surface of the water.
Factual errors: Earlier in the film the XO gives an order to, "Rig for ultra quiet." However, the order is given over the votes PA system, which is a procedure that is anything but "quiet", much less "ultra" quiet.
Factual errors: According to Hunter, torpedoes must run for at least 1000 yards before they can be armed. On modern torpedoes, this run to enable can be disabled, arming the torpedo the moment it leaves the tube.
Factual errors: Red caps would only be worn during a drill. For instance, if the boat was going through a reactor scram drill (essentially turned off), the captain would wear one if he was back in the engineering spaces. Wearing the cap is saying "I'm not really here." Ramsey is seen wearing a red cap after he has been arrested, one time when he is certainly not participating in a drill.
Factual errors: When Ramsey yells at Hunter in front of the crew, he could have been detained right there under UCMJ article 133 which is Conduct Unbecoming. When he strikes Hunter at the end, he would have been immediately detained under UCMJ article 128 for assault.
Continuity: Ramsey strikes Hunter on the left side of his face when Hunter refuses to give him the missile key after being asked a second time, leaving him with a cut on his cheek. At the subsequent hearing at Pearl Harbor, the cut has disappeared.
Incorrectly regarded as goofs: Originally, US Navy submarines were named for fish and other sea creatures and US Navy battleships were named after states (like the WWII USS Alabama.) However, the naming convention for US naval vessels has changed. US Navy submarines are now named for both cities (fast attack boats) and states (ballistic missile boats.)
Incorrectly regarded as goofs: The captain has a dog. Having a pet on a submarine would not conform to any Navy regulation. There may have been pets on subs in WWII, but nowadays that would be (1) cruel to the animal and (2) unsanitary to the crew. However, this matter is addressed early in the film, when Dougherty mentions to Hunter that Ramsey "takes that dog everywhere" and that "the Navy looks the other way because he's Ramsey," with Zimmer adding, "The Navy looks the other way because he's one of the few skippers left who's actually seen some combat."
Factual errors: Several times in the movie it is stated that the Russian separatists would have to fuel the ICBMs they gained control of before being able to launch them. Prior to the development of solid propellant, ICBMs had to be stored dry because the liquid fuel corroded the missiles' fuel tanks. The time period in which the movie is set is around the year 1995, at which time, all American and Russian ICBMs used solid propellant. Thus, the missiles were stored with fuel already in their tanks, making pre-flight fueling unnecessary. Therefore, if the Russian separatists gained control of the launch codes, the missiles could have been launched immediately.
Factual errors: Lipizzaners are from what is modern day Slovenia - neither Spain nor Portugal. They do perform in the Spanish Riding School which is located neither in Spain nor Portugal, but in Vienna, Austria. They ARE born black and only those that turn white are chosen for the school.
Factual errors: Not only is Capt. Ramsey wrong about the color of the Lipizzans, he also doesn't know anything about their training. He says "Their training program is simplicity itself. You just stick a cattle prod up their ass and you can get a horse to deal cards." Full training of the Lipizzan stallions one sees in the shows takes six years to complete. The classical dressage methods that are used for their training are based on rewarding the horse instead of punishing it.
