The Novembers (627): The November (Type 627) class was the Soviet Union’s first effort at developing nuclear attack submarines. The 627s were rough contemporaries of the Skate and Skipjack class attack boats of the U.S. Navy (USN), although they were somewhat larger and generally less well-arranged. Displacing 4750 tons submerged, the thirteen 627s could make thirty knots and carry twenty torpedoes (launched from eight forward tubes). Visually, the 627s resembled a larger version of the Foxtrot class diesel-electric subs; the Soviets would not adopt a teardrop hull until the later Victor class. The Novembers were renowned in the submarine community for their noise; louder than any contemporary nuclear sub, and even preceding diesel-electric designs.
