Corrected entry: When the Orlando finally gets a shooting solution on the Stingray and the admiral calls to gloat, he is quite surprised when Dodge informs him he's already fired his torpedoes. In reality, the sonar officer on the Orlando would have been screaming "Torpedo in the water!" as soon as the first torpedo left the Stingray.
Corrected entry: This movie appears to take place in 1996. The first production Seawolf-class submarine was launched in 1998.
Corrected entry: Nitro could not have operated as a connection for the radio circuit. The human body is not conductive enough.
Corrected entry: The salute that Stepanek gives his father is incorrect. A proper U.S. military salute does not show the back of the hand; it shows it palm-down, angled slightly to the temple.
Corrected entry: During the beginning of the movie, Dodge is referred to as Captain by both of the admirals. When 'Captain' Dodge is meeting his crew for the first time, he introduces himself to his XO as 'Lt. Commander Dodge'. At the end of the movie, the 3-star Admiral addresses Dodge as 'Commander Dodge'. To the best of my knowledge, Lt. Commander, Commander and Captain are three different ranks.
Corrected entry: The qualification badge of Lt. Lake's uniforms through most of the movie is that of a surface warfare officer. At the end of the movie she finally wears the correct qualification badge, the submarine warfare badge or commonly called "dolphins."
Corrected entry: When Graham is on the Orlando he is a flag officer. Although he has command of the task force in the exercise he can not take over command of the ship he is on. In Navy Regulations the Captain or Commanding Officer of the vessel has sole discretion over operation of such vessel and can not be overruled by a flag officer. Even if he is removed from command the first officer would maintain the authority until the ship returned to port.
Corrected entry: Stepanik is introduced in the crew boarding scene as an Engineman First Class, however in the homecoming scene, his uniform insignia is that of a Machinist's Mate First Class.
Corrected entry: As the crew leaves the Stingray in dress uniform near the end, Lieutenant Lake's Mary-Jane style heels are completely non-regulation. While many of the crew are misfits and don't properly wear the uniform (or cut their hair) anyway, Lake was a "by-the-book" officer consistently through the whole film. United States Code Title 10 > Subtitle A > Part II > Chapter 45 > Section 772 > Statute F specifically allows that "While portraying a member of the Army, Navy, Air Force, or Marine Corps, an actor in a theatrical or motion-picture production may wear the uniform of that armed force if the portrayal does not tend to discredit that armed force" so the argument that actual uniforms cannot be worn in movies does not apply (here or ever).
Corrected entry: There are numerous references to the word "quadrant," being substituted for "region." A quadrant is one-fourth of something. It is not a generic, military-sounding name for a region.
Corrected entry: In the credits there is a name for a singing waitress named Annie Talbot. As far as I can tell, there is no singing waitress in this movie. (01:28:20)
Corrected entry: Near the end of the movie, the Stingray surfaces to run on top as it approaches the target ship. At some point afterwards, Dodge decides to take a shot at the ship with two torpedoes. Dodge is using the periscope to get the range, etc. to the target, and then fires the torpedoes. First, wouldn't they be on the bridge (outside) if they were running on the surface? And second, wouldn't the torpedoes be running near the surface of the water if they had been fired from a sub that was on the surface, instead of what appears to be deep water? In both cases it appears as if the Stingray were submerged when they fired the torpedoes, not running on top as it showed prior to firing the torpedoes. No order was given to "dive" before this series of events.
Corrected entry: The Stingray, the diesel sub in the movie, is supposed to be the SS-161 Stingray and is even painted as such. The real Stingray was SS-186 Decommissioned, 17 October 1945, at Philadelphia Navy Yard, Philadelphia, PA.; Struck from the Naval Register, 3 July 1946; Final Disposition, sold for scrapping in 1947.

Corrected entry: When Stapanak gets to the engine room you can see that the rocker arms are not moving, But yet they are moving fast up to the tanker. (01:11:50 - 01:12:20)
Corrected entry: When Capt. Dodge enters the Vice Admiral's office at the beginning of the movie, he salutes. Navy sailors do not salute indoors or uncovered.
Corrected entry: When the stingray is trying to evade the Orlando by going between the rudders of an oil tanker, after Lt. Lake takes the control ("Balls to the walls, boys"), there are two different sets of actors at the rudders and the camera goes back and forth between the two sets of actors.
Corrected entry: Martin Pascal's index finger goes from the lid of coffee to the side of can a couple of times while yelling at Buckman. (00:18:15)
