Jack Ryan: [after a torpedo broke up harmlessly on the Red October's hull] What just happened?
Capt. Bart Mancuso: Combat tactics, Mr. Ryan. Ramius closed the gap before the torpedo could arm itself.
Jack Ryan: So that's it?
Captain Ramius: Not quite. Right now, Tupolev is disarming all safety measures so that the next torpedo will arm immediately. He won't make the same mistake twice.
