Lieutenant Melekhin, Engineer - Red October: [in Russian to shipmates after Ryan chokes on a Russian cigarette] He's turning green.
Dr. Petrov: [Ramius has taken the Political officers Missile key and kept it] Sir! The reason for having two keys is so that no one man may...
Captain Ramius: May what, Doctor?
Dr. Petrov: Arm the missiles Captain.
Captain Ramius: Mmm, thank you for your concern Doctor
Capt. Bart Mancuso: How did you know that his next turn would be to starboard?
Jack Ryan: I didn't. I had a 50/50 chance. I needed a break. Sorry.
Capt. Bart Mancuso: That's all right, Mr Ryan. My Morse is so rusty, I could be sending him dimensions on Playmate of the Month.
Admiral James Greer: [after the meeting where Jack Ryan has just explained - quite boldly - his theory that Capt. Raimus is defecting] I told you to speak your mind Jack, but Jesus
[laughing a little]
Admiral James Greer: ...!
Jeffrey Pelt: I can't ask any of these characters to go. One, they don't believe in it. Two, they'd never stake their reputation on a hunch. Whereas you...
Jack Ryan: ...are expendable.
Jeffrey Pelt: Something like that.
[Shootout in the missile room]
Captain Ramius: Hey, Ryan, be careful what you shoot at. Most things in here don't react too well to bullets.
Jack Ryan: Right.
[Moves closer to enemy, who fires several shots at him]
Jack Ryan: *I* have to be careful what *I* shoot at?
Seaman Jones: [Jonesy is teaching Beaumont] Hear it now?
Beaumont: [resigned] No.
Seaman Jones: Beaumont, at Caltech we used to do this in our sleep! You hear it now?
Beaumont: Wait a minute...
Seaman Jones: Uh oh...
Beaumont: Disparaged surface clutter...
Seaman Jones: Yeeeesssss?
Beaumont: I should go to SAPS?
Seaman Jones: Correct! Seaman Beaumont, Signal Algorithmic Processing System. Give it a week and you'll be teaching at Caltech. So, like Beethoven on the computer, you have laboured to produce... a biologic.
Beaumont: A what?
Seaman
Jones: A whale, Seaman Beaumont, a whale. A marine mammal that knows a hell of a lot more about sonar than you do. Train her around to 269 and let's try it again?
Captain Davenport: They're pinging away with their active sonar like they're looking for something, but nobody's listening.
Jack Ryan: What do you mean?
Captain Davenport: Well, they're moving at almost forty knots. At that speed, they could run right over my daughter's stereo and not hear it.
Jack Ryan: [after a torpedo broke up harmlessly on the Red October's hull] What happened?
Capt. Bart Mancuso: Combat tactics, Mr. Ryan. By turning into the torpedo, the captain closed the distance before it could arm itself.
Jack Ryan: So that's it?
Captain Ramius: Not quite. Right now, Captain Tupolev is
removing the safety features on all his weapons. He won't make the same mistake twice.
Jack Ryan: I've got a line on those doors. You know what they are?
Admiral James Greer: A nearly silent propulsion system?
Jack Ryan: [taken aback] How did you know that?
Admiral James Greer: The captain of the sub we had following her radioed in. Thing up and disappeared right in front of 'em.
