It was impossibly expensive, extraordinarily dangerous, and completely unarmed. The U.S. Navy’s state-of-the-art NR-1 nuclear powered submersible was the Cold War’s most closely guarded - and revolutionary - secret. In 1966, after the U.S. almost lost a hydrogen bomb off the coast of Spain, Admiral Hyman Rickover - father of the nuclear navy - outmaneuvered Congress and steamed full speed ahead on his brainchild: a spy mission and deep ocean recovery submarine with a miniature nuclear reactor that could navigate the ocean floor for weeks at a time. But operating at such depths would also cut off the crew should rescue become necessary. Now, an original crew member revels the true story of America’s Secret Submarine - the triumphs and near disasters of the super-secret NR-1 are told through first person accounts by those who alternately suffered through, and exalted in, its construction and initial operation - and then dared go where no men had gone before.
