Kenneth Sewell spent eight years in the submarine service with classified duties in nuclear engineering technology. Five of those years were aboard the USS Parche, the most decorated ship in the history of the United States Navy and America's top espionage submarine. According to the best selling book, Blind Man's Bluff, the Parche reportedly tapped the undersea communications lines of the Soviet Union during the Cold War and retrieved lost Soviet weaponry from the ocean floor. Since leaving the Navy, Mr. Sewell has worked in the defense industry holding both Department of Defense and Department of Energy security clearances. In researching this book, Mr. Sewell had access to recently declassified intelligence files in the U.S. and Soviet military archives that were opened after 1991, among other sources.
