The nuclear-powered USS Skate was the first submarine to break the surface of the North Pole. Author James Calvert captained the Skate and his book details a series of exploratory underwater voyages north before he and his crew finally found a way to the top and triumphantly smashed through the polar ice-cap on 17 March 1959. This revised edition of Surface at the Pole: The Extraordinary Voyages of the USS Skate includes footnotes and images of the Skate.
