While the use of drones is now commonplace in modern warfare, it was in its infancy during the Vietnam War, not to mention revolutionary and top secret. Drones would play an important–and today largely unheralded–role in the bloody, two-decade U.S. air war over Vietnam and surrounding countries. Drone aircraft spotted targets for manned U.S. bombers, jammed North Vietnamese radars and scattered propaganda leaflets, among other missions. This book is based on military records, official histories and published first-hand accounts from early drone operators, as well as on a close survey of existing scholarship on the topic. Illustrated throughout.
