Cold Is the Sea followed, in 1978, Edward L. Beach's extraordinarily successful first two novels, easily meeting their high standards. But unlike these earlier World War II novels, this book is set fifteen years after the war's end as the U.S. Navy converts its fleet of conventional submarines to nuclear-powered ships. The focus of the story is the USS Cushing, whose sixteen missile silos carry more explosive power than all the munitions used in both world wars. The Cushing is on a secret mission to the Arctic Ocean to determine whether her missiles are effective if fired from beneath the ice. When the submarine is incapacitated, with a suspicious Russian sub lurking in the vicinity, the scene is set for a dramatic thriller, rich in technical detail and submarine lore.
