The dropping of two atom bombs on the Japanese cities of Hiroshima and Nagasaki and their shocking aftermath finally ended World War II in the eastern theatre. But they weren''t the only experimental weaponry at the time. In this fascinating account, Chris McNab examines the development of a range of hitherto unknown and at times shockingly effective weapons that were developed and unleashed on an unsuspecting world over the course of the war. They include the bouncing bomb, the V2 rocket that caused terror in London, Antwerp and Liège in the later years of the war, Bat Bombs, the X-class submarine and the Yokosuka MXY7 Ohka suicide attack aircraft.Containing black and white images throughout, Secret Weapons of World War II examines the thinking behind these weapons, the research and development that led to their creation, their effectiveness in deployment, and ultimately how these weaponry developments fundamentally changed the balance of the war.
