Many air forces can conduct missions such as air superiority and ground attack, but only the US Air Force has truly global reach. For more than five decades, the essential enabler of this global reach has been the KC-135 Stratotanker. Unarmed and unglamorous, the KC-135 has been one of the most successful and enduring aircraft in US Air Force history. Primarily based on the author’s extensive access to operational KC-135 aircraft on the ground and in flight, this book contains the most detailed photographic documentation of the KC-135 inside and out that has ever been published, as well as color profiles of the KC-135R in the markings of every major USAF command that has operated that variant.
