The Sargo Class submarine USS Seawolf was one of the most active American submarines in the early war in the Pacific. Her extraordinary service was kept secret for operational reasons during the war, but would later be described to two reporters by her chief radioman, and published as a book in 1945.
The first class of nuclear submarines were a learning experience for the Soviet Navy. The November class boats experienced numerous difficulties and accidents, culminating in what has been described as a potential “Underwater Chernobyl."
