In 1944, in response to the bombing of German cities and factories by the Allies, an inventor named Erich Bachem developed 'Projekt Natter' ('Viper'), an extraordinary, highly-secret, vertical take-off, semi-expendable, single-seat rocket-fighter armed with a nose-mounted 'honeycomb' of 73-mm or 55-mm spin-stabilized air-to-air rockets as well as 30-mm cannon. The Natter was intended to offer high-speed defense of key targets. Once blasted into the air from its vertical launch tower, the pilot of the Natter was to climb towards an enemy formation using an internal rocket, target an enemy bomber and fire his battery of rockets. He would then use the remaining kinetic energy to climb higher than the bombers in order to mount a ramming attack. Just before impact, the pilot was to trigger a mechanism that would activate an ejection seat and separate the rocket unit, which would return to earth by means of an automatically deployed parachute for reuse. Relatively little has been published on the Natter and this book will provide a detailed and definitive account of this unusual but fascinating aircraft. This will be required reading for all those interested in the history of the Luftwaffe during World War II, particularly for those fascinated by the radical and revolutionary projects which German aircraft designers contrived toward the end of the Nazi regime.

Germany’s air ministry was quick to grasp the potential of the jet engine as early as 1938 and by 1939 several German aircraft manufacturers were already working on fighter designs that would utilize this new form of propulsion. Rocket engines too were seen as the way of the future and companies were commissioned to design fighters around them. As the Second World War began, the urgent need to bring these advanced new types into production saw a host of innovative aircraft designs being produced which would eventually result in Messerschmitt’s Me 262 jet fighter and the Me 163 rocket-propelled interceptor. And as the war progressed, efforts were increasingly made to find better ways of utilizing jet, rocket and latterly ramjet engines in fighter aircraft. Aviation companies from across Germany set their finest minds to the task and produced some of the most radical aircraft designs the world had ever seen. They proposed rotating wing ramjet fighters, arrowhead-shaped rammers, rocket-firing bat-winged gun platforms, sleek speed machines, tailless flying wings, tiny mini fighters and a host of others ranging from deadly looking advanced fighters to downright dangerous vertical launch interceptors. Secret Projects of the Luftwaffe Volume 1: Jet Fighters 1939-1945 by Dan Sharp, based on original research using German wartime documents, offers the most complete and authoritative account yet of these fascinating designs through previously unseen photographs, illustrations and period documentation from archives around the world.

The capability of MNCs to create, transfer and combine knowledge from different locations is an important determinant of corporate success. This book uses examples of knowledge-based firms - Hewlett-Packard Consulting & Integration, Siemens, Mazda, and Maekawa - to show that knowledge-based marketing is key to a sustainable competitive advantage.

The growth in size, lethality, and technology of the German Luftwaffe was of concern to some defense planners in the United States before American entry into the war. Learning about the Luftwaffe became a significant effort once the conflict broke out in Europe. From defectors with German aircraft to battlefield trophies and combat crew reports, the race to understand German aero technology took on sometimes heroic proportions. After the war, German technology infused American aerospace developments in many ways: German ribbon parachutes were evaluated for high-speed bailouts; sweptwing leading edge slat technology benefited the F-86 Sabre; overall comprehension of sweptwing benefits to fast jet aircraft was validated; pulse jet V1s and supersonic V2 rockets boosted American drone weapon, ballistic missile, and space exploration efforts. In this volume, Frederick A. Johnsen traces that path of discovery.
