As the Nazi advance across Europe stalled, Adolf Hitler repeatedly told his military advisers and inner circle that Germany possessed Wunderwaffen - miracle weapons - that would turn the tide and bring the Germans ultimate victory. But was he simply boasting out of desperation, or were the 'miracle weapons' real?

Ideas that other governments considered too outrageous were funded by the Third Reich. At this time, German scientists and engineers led the world in the fields of aviation research, rocketry, and the quest for alternative sources of energy. They even came perilously close to beating the British and Americans in the search to build the first atomic bomb.

This book describes the Nazis' secret plans to produce weapons of mass destruction, and shows how they almost succeeded in defeating the Allies in World War II.
