World War II began with an impressive display of technological power as German Panzer divisions swept across Europe. By the time it ended in 1946, the invention of completely new technologies such as radar and the atomic bomb had changed the face of international warfare forever. This book covers the major technological breakthroughs and the new and adapted technology used throughout the Second World War, from the improvements to existing technology such as the tank and fighter planes to the invention of new technologies such as the doodlebug and enigma machine. It examines the impact of scientific progress on the course and outcome of the war, and shows how new technologies resulted in destruction on an unprecedented scale. This book is a clear, well-written, authoritative text packed with useful information, fascinating, thought-provoking photographs, paintings, posters, cartoons and maps. It has a wealth of panels that give biographical details of the major personalities, statistical information, eye-witness accounts and poetic responses to the war. The book ends with a comprehensive date list, glossary and a list of further resources.
