Boeing's mighty B-52 Stratofortress has seen continuous operational service with the United States Air Force since the type was introduced in 1957. The aircraft has been upgraded several times and has assumed many different new roles since it was originally conceived and then provided the key airborne platform for America's strategic nuclear force. It is predicted that it will serve as a front-line aircraft until 2040. Apart from the formidable threat it provided during the long years of the 'Cold War', the aircraft has played a significant part in all US overseas operations since Vietnam. The more recent include Desert Storm in 1991, the Balkan conflict, Afghanistan and the liberation of Iraq. Over 700 were built and around 80 remain in service. This book includes chapters on Concept Requirement, Design and Development, Production, Evolution and Variant Models, Operational Tasking, Operational History (with first-hand accounts from crews), Weapons and Equipment Carried, Flying the Aircraft and Current Service Operations. It will be highly illustrated with many original shots taken aboard B-52s during a recent visit by the author to their American base, together with archive material and also colour profiles.
