"Silent but deadly" - Osprey's "US Nuclear Submarines: The Fast Attack" takes a fresh look at the controversial design and development of the nuclear submarine. The United States Navy operates the largest fleet of nuclear submarines in the world. The advent of nuclear power transformed the submarine from a slow underwater vessel, incapable of staying submerged for long periods, into a weapon of stealth and endurance. Jim Christley, a former submariner, uses his own experience of serving aboard these vessels and a wealth of technical information to explore the many engineering issues and trade-offs that have dominated the intriguing story of the US nuclear submarine.
