Book excerpt: While the Allies largely relied on mass production to help them win World War II, Germany put a great deal of their limited resources into new technologies and wonder weapons. In addition to these tangible assets, which were used with varying degrees of success, the drawing boards of Germany were littered with dozens of advanced designs that never reached the prototype or production stages. Many of these operational and paper projects advanced the pace and influenced the direction of aircraft development in the decades following World War II, with many of the German engineers responsible for these innovations seamlessly continuing their roles in the United States and the USSR. Modellers have had a long fascination for the Luftwaffe's jet arsenal and secret weapons of fact and fiction and this new Osprey Masterclass will explore the Luftwaffe jets and rocket planes that saw service at the end of World War II.
