Other mistake: In all scenes where the submarine is running on the surface the surface search radar is rotating CCW (viewed from above). All surface search radars rotate CW.

Directed by: Kathryn Bigelow
Starring: Liam Neeson, Harrison Ford, Christian Camargo, Peter Stebbings, Roman Podhora, Sam Spruell
Factual error: Many shots of the submarine in drydock show Halifax, Nova Scotia's MacKay and MacDonald bridges in the background.
Captain Alexei Vostrikov: We will not fail.
Trivia: The 'American' destroyer seen from far away in several shots is actually the decommissioned destroyer HMCS Terra Nova.
Question: When they fire the test missile it appears to come out of the sail. That would be incorrect, no? (00:49:30)
Answer: The movie is correct on this. The early Soviet ballistic missile subs like this one had the missile launcher in the sail, carrying 3 missiles. Missile tubes integrated into the hull, and the ability to fire while completely submerged, didn't come til later.
