UNMANNED AERIAL VEHICLES Robotic Air Warfare 1917–2007 - Original PDF
نویسندگان: خلاصه: Unmanned aerial vehicles (UAVs) are the most dynamic field of aerospace technology, and potentially the harbingers of new aviation technology and tactics. They have only emerged from the shadows in recent years, but in fact have been in use for decades. After some limited use in World War II, UAVs began to emerge as a substitute for manned reconnaissance aircraft in the 1950s for missions deemed too dangerous to risk an aircrew. Used in significant numbers in the Vietnam War as well as less-heralded missions such as spy flights over China in the 1950s and 1960s, the contemporary UAV began to emerge in the 1980s. This book examines the development of this unique and mysterious technology, revealing how it has changed combat through the years and speculating on its potential to transform the nature of warfare in the future. Steven J Zaloga examines the pioneering use of UAVs conducted by the Israeli air and the use of UAVs during Operation Desert Storm. Packed with rare, recently declassified photographs and detailed full-color cutaways, this title goes on to investigate the wide deployment of UAVs over Iraq and Afghanistan today, and considers the possible future of the UAV as an actual military weapon.
Air Warfare: History, Theory and Practice - Original PDF
نویسندگان: خلاصه: Air Warfare provides an introduction to the subject's theory, history and practice. As well as delivering an up to date look at the strategy, and historiography of air power, Peter Gray explores the theories behind air power and looks at the political, legal and moral dimensions of the application of air power. Topics covered include: - Key military strategists and their legacy - Air power's strategic effects - Leadership, management and command - Tactics, technology and operations The book draws on primary sources including official narratives and published reports, examines key thinkers in the study of air power, and discusses topics such as concepts of warfare as an art or science, cultural perceptions of air power, and the experience of being an airman. With its broad scope and thorough coverage of a range of key topics, Air Warfare takes air power beyond the study of individual campaigns, or controversies, providing a multi-disciplinary approach to air power studies.
Rhetoric and Reality in Air Warfare: The Evolution of British and American Ideas about Strategic Bombing, 1914-1945 (Princeton Studies in International History and Politics) - Original PDF
نویسندگان: خلاصه: A major revision of our understanding of long-range bombing, this book examines how Anglo-American ideas about "strategic" bombing were formed and implemented. It argues that ideas about bombing civilian targets rested on--and gained validity from--widespread but substantially erroneous assumptions about the nature of modern industrial societies and their vulnerability to aerial bombardment. These assumptions were derived from the social and political context of the day and were maintained largely through cognitive error and bias. Tami Davis Biddle explains how air theorists, and those influenced by them, came to believe that strategic bombing would be an especially effective coercive tool and how they responded when their assumptions were challenged.Biddle analyzes how a particular interpretation of the World War I experience, together with airmen's organizational interests, shaped interwar debates about strategic bombing and preserved conceptions of its potentially revolutionary character. This flawed interpretation as well as a failure to anticipate implementation problems were revealed as World War II commenced. By then, the British and Americans had invested heavily in strategic bombing. They saw little choice but to try to solve the problems in real time and make long-range bombing as effective as possible.Combining narrative with analysis, this book presents the first-ever comparative history of British and American strategic bombing from its origins through 1945. In examining the ideas and rhetoric on which strategic bombing depended, it offers critical insights into the validity and robustness of those ideas--not only as they applied to World War II but as they apply to contemporary warfare.
COMBAT PAIR: The Evolution of Air Force-navy Integration in Strike Warfare - Original PDF
نویسندگان: خلاصه: This report documents the exceptional cross-service harmony that the U.S. Air Force and U.S. Navy have steadily developed in their conduct of integrated strike operations since the first Persian Gulf War in 1991. That close harmony contrasts sharply with the situation that prevailed throughout most of the Cold War, when the two services maintained separate and unique operating mindsets and lacked any significant interoperability features.
