The USS Greeneville’s mission on February 9, 2001, was a simple one: take sixteen civilian guests out for a pleasure cruise in the waters south of Oahu, entertain them at lunch in the galley, impress them with a demonstration of what a nuclear-powered attack submarine can do. Using eyewitness accounts, court of inquiry testimony and findings, and a narrative timeline of those frantic minutes beneath the sea, Eric Fein tells the tragic story of the Greeneville’s collision with the fishing vessel, the Ehime Maru, that resulted in the deaths of nine Japanese fishermen and students.
