No radio distress call ever crackled from the submarine USS Grunion. In 1942, under the fog of World War II, the vessel simply vanished without a trace. For nearly sixty-five years, only a dead silence lingered regarding the fate of the sub and its seventy-man crew—until now. Here author Peter F. Stevens reveals the incredible true story of the search for and discovery of the Grunion—as well as the navy's shocking and willful cover-up of the submarine's baffling disappearance. The Grunion was discovered in 2006 after a decades-long search by the Abele brothers, whose father commanded the submarine and met his untimely death aboard it, but one question remained: what sank the USS Grunion? Now, for the first time ever, Fatal Dive reveals the answer: one of the Grunion's own missiles. The navy knowingly sent the Grunion out with faulty torpedoes, and Fatal Dive reveals damning and never-before-published government documents that provide irrefutable evidence of its shameful cover-up. Intriguing and explosive, Fatal Dive finally lays to rest one of World War II's greatest mysteries.
