From the deadly undersea warfare of World War II through the silent Cold War stand-offs in the deep, to the cutting edge technology of the modern U.S. Navy, submarines have evolved into the front line of our nation's defense at sea. And the men who sail them have become heroes above and below the waves. These are their stories-in their own words. In Sub, author Mark Roberts has compiled insightful interviews and recollections from the submarine veterans themselves-accompanied by detailed photos and illustrations of both man and machine at work.

It's a gripping chronicle of undersea warfare as told by those who know firsthand what it means to drop through the hull of a boat, to sink into the dark, freezing waters of the deep-and to have death never more than one torpedo away.
