The inter-war years between 1918 and 1939 saw the newly created Royal Air Force fighting for its very existence politically, being dispatched to the remotest corners of the British Empire and its Protectorates in various policing roles and then finally engaged in a headlong rush to modernize in the face of the new German Fascist regime that was threatening British and European freedom. Yet this important period in RAF history and its effect on political and military rationale during the period has never been completely documented. This exhaustive and comprehensive reference is the most detailed work to be published on the subject. The author gives full information on the changing structure of the Force during the period, squadron operations, political machinations and their effects, the airplanes and their equipment, the personnel, technical advances in navigation and breakthroughs achieved in engine performance. The book is cross-referenced throughout, extremely well illustrated and contains an abundance of location maps and other diagrams. This book will become a Bible for anyone interested in the history of the RAF.This work has been reviewed by personnel at the RAF Historical Branch who praise it.
