chunk: Captain Viktor Tupolov, a former student of Ramius and commander of the Soviet Alfa-class attack submarine V. K. Konovalov, has been trailing what he initially believes is an Ohio-class vessel. Based on acoustical signature information, Tupolev realizes that it is Red October, and proceeds to pursue and engage it. The two U.S. submarines escorting Red October are unable to fire due to rules of engagement, and Red October is damaged by a torpedo from the Alfa. After a tense standoff, Red October rams Konovalov broadside and sinks it.
  The Americans escort Red October safely into dry dock in Norfolk, Virginia, where Ramius and his crew are taken to a CIA safehouse to begin their Americanization. Ryan is commended by his superiors and flies back to his posting in London.
