The Hunt for Red October is Tom Clancy's 1984 debut novel. The story follows a CIA analyst who leads a group of United States Navy officers to take possession of a cutting-edge Soviet nuclear submarine from 26 defecting with her Soviet officers, and the intertwined adventures of Soviet submarine captain Marko Aleksandrovich Ramius and Jack Ryan, a Marine turned CIA analyst. It was loosely inspired by the mutiny on the Soviet frigate Storozhevoy in 1975.
