ABSTRACT This thesis examines the development of RAF high command of the Metropolitan Air Force (MAF) during the Second World War. It sheds new light on the re-organisations of the Air Ministry in 1934, the RAF Command structure in 1936, and the tri-service debate in 1937 concerning the RAF proposal to establish a Supreme Air Commander (SAC). It reveals that while frontline expansion created an impetus for re-organisation, it was operational readiness that was the dominant factor in the re-structuring of the RAF. It examines the transition in RAF frontline organization from the mono-functional command system of 1936 to the multi- functional organisation that emerged after 1943 by looking at command structure and practice, personalities, and operational thinking. This study builds on the established historiography but challenges the accepted explanation of RAF reforms in the 1930s. It addresses a significant gap in the literature concerning the way the frontline was directed by the War Cabinet and the Air Ministry. In doing so it seeks to establish a new starting point for the analysis of RAF high command by providing an assessment of the effectiveness of the reforms of the 1930s to the higher command of MAF operations during the Second World War. i ACKNOWLEDGEMENTS AND DEDICATION I must begin with my great thanks to Air Chief Marshal Sir Glenn Torpy for his creation of the Chief of the Air Staff’s Portal Fellowship which I was so fortunate to secure and which has guided my study and this thesis. I would also like to thank Air Chief Marshal Sir Stuart Peach and Sebastian Cox who, more than any others, have through their interest, enthusiasm, encouragement, intellect and knowledge stimulated and sustained my lifelong interest in the history of the Royal Air Force. I have been enormously fortunate to have been mentored by Dr Peter Gray who has expertly guided me through the foggier times that inevitably afflict the part- time PhD student. Dr Gray’s supervision allowed me the freedom to explore this subject as the evidence demanded and his leadership prevented the descent into the many rabbit holes of ‘great interest’ that enticed me along the way. I would also like to thank the staff of The National Archives at Kew, Mr Mike Hatch and the Staff of the RAF Historical Branch, the RAF Museum, and Mr Chris Hobson of the Joint Services Command and Staff College for all their help and friendly support. My final thanks, appreciation, and acknowledgement must go to Catherine, my wife, for all her encouragement, love, and support during the many hours I have spent in researching and writing this work; a work which is rightly dedicated solely to her. ii ABBREVIATIONS The listed abbreviations and codewords will be used throughout this document without further explanation after their first use. This will be either in full in the text or for abbreviations that feature little in the subsequent discussion in an associated footnote. On a small number of occasions, such as a title, they may be used in full to preserve the style of the paper. They have been placed into functional or institutional groupings to make reference easier than there being contained in a long unstructured but alphabetical list.
