In The Hunt for Red October, Tom Clancy displayed his knowledge of military technology. Now he turns his attention to a subject that has inspired much of his work, the submarine. Drawing on recent research, he examines its history and evolution from the earliest days, through World War II and the development of nuclear powered and nuclear-armed vessels, up to recent technological breakthroughs, and considers its role in the modern world. He explains in detail the particular problems involved in underwater warfare - in navigation, communication, weaponry and noise suppression - and reveals the special skills and qualities of the new breed of men who spend their working lives under the sea. Tom Clancy's best-selling novels include Red Storm Rising, Patriot Games, Cardinal of the Kremlin, Clear and Present Danger and The Sum of All Fears.
