This book contains a history of all United States Air Force Tactical Air Command flying units that were resident in the United Kingdom during the period 1950 to 1992. ‘From the cockpit’ testimony from aircrew who were assigned to the individual squadrons and wings is an integral part of the narrative; which is supported by 467 illustrations, 168 of which are in colour. The tactical nuclear mission was central to the operations of many of the UK based units and is covered in detail from its beginnings in 1952 with the arrival the 20th TFW and the 47th Bombardment Wing, to the adoption by NATO of the doctrine of ‘Flexible Response’ and the eventual end of the Cold War. Also Included also are sections on the units which were temporarily deployed to the United Kingdom in support of the USAF and NATO operations. The comprehensive Appendices contain essays on individual aircraft development, international events which had a direct bearing on the missions and deployments of the individual units, the support aircraft used by the wings, and Maps, Tables and Profiles.
