Nicholas George Shadrin, born Nikolai Fedorovich Artamonov (1922 – December 1975[1][2]), was a Soviet naval officer serving in Gdynia, Poland who defected to the United States of America in 1959.
After joining the Soviet Navy he received advanced training in nuclear missiles, and at the age of 27 became the youngest destroyer captain in the fleet.
With Navy restrictions and Gora's family's anti-communism making marriage impossible, the two defected by commandeering a naval launch to Sweden.

Bagley, James Angleton had warned Shadrin's American handlers, CIA officer Bruce Solie and FBI agent Elbert Turner, to not let him travel out of the United States, but they allowed him to go to Canada in 1971 to meet with the KGB and let him travel to Vienna, Austria, in December 1975 to meet with his KGB recruiter, Igor Kochnov.
