Fyi, based on a true story:

https://en.wikipedia.org/wiki/Soviet_frigate_Storozhevoy

"Gregory D. Young was the first Westerner to investigate the mutiny as part of his 1982 master's thesis Mutiny on Storozhevoy: A Case Study of Dissent in the Soviet Navy. One of 37 copies of Young's thesis was placed in the Nimitz Library of the United States Naval Academy where it was read by Tom Clancy, then an insurance salesman, who used it as inspiration to write The Hunt for Red October."

There is a great YouTube video on the subject if you are interested. Its 38 minutes long but worth the watch.
