Armament. 6 × 21-inch (533 mm) torpedo tubes. USS Seawolf (SSN-575) was the third ship of the United States Navy to be named for the seawolf, the second nuclear submarine, and the only US submarine built with a liquid metal cooled (sodium), beryllium - moderated [2][3] nuclear reactor, the S2G. [4] Her overall design (known as SCB 64A) was a ...
List of sunken nuclear submarines. Nine nuclear submarines have sunk, either by accident or scuttling. The Soviet Navy lost five (one of which sank twice), the Russian Navy two, and the United States Navy (USN) two.
