Shadrin was born in the Soviet Union in 1922. After joining the Navy he received advanced training in nuclear missiles, and at the age of 27 became the youngest destroyer captain in the fleet. Stationed in Gdynia, Poland in 1959, he fell in love with a Polish woman, Ewa Gora. With Navy restrictions and Gora's family's anticommunism making marriage appear impossible, the two defected by commandeering  a naval launch to Sweden. The Central Intelligence Agency then brought Shadrin and Gora to the United States. Shadrin's information proved particularly useful to the Office of Naval Intelligence. Working with the ONI under new identities, Shadrin gained an MA and PhD in engineering, and Gora opened a dental practice. Later, with ONI unable to gain Shadrin higher level security clearances, he was assigned to translation in the Defense Intelligence Agency. Shadrin was engaged in various counter-intelligence assignments during the Cold War after being approached by the KGB in 1966. He disappeared on assignment in Vienna, Austria in  December 1975, apparently kidnapped by KGB agents. Later, Oleg Kalugin stated that Shadrin had died an accidental death during the kidnapping, apparently of a heart attack.
