Spoke to the staff of the Submarine Force Library and Submarine Force Museum, where Nautilus, less her reactor, “floats” in a perpetual bed of concrete. They, and their Officer in Charge, Commander Ben Amdur, have been our gracious hosts the last three days. We spent most of our time focused not on the fascinating story of how Admiral Rickover steered USS Nautilus to life in 1954, and more on why it was that nuclear submarines became so important to our Presidents in their effort to win the Cold War battle over communism — part of the focus of my recent book.
