Author is an avid aviation photographer and this book features full-colour images. Covers every version of the KC-135 tanker. Part of Modern Military Aircraft Series.

The first KC-135A was rolled out on July 18, 1956 - nearly 70 years ago - and, amazingly, half of those constructed during the following ten years are still active. Described as a "force multiplier," providing aerial refueling to extend range or enable combat aircraft to remain on station for significantly longer periods, the KC-135 is unmatched. Ordered primarily as a tanker, it subsequently took on roles in strategic reconnaissance, airborne command post, treaty verification, weather monitoring, air sampling, test and evaluation support, VIP, aircrew trainer, airlift, and much more. While many KC-135 aircraft with a unique tasking have been replaced, some have an open-ended life expectancy and should exceed 80 years' service. To date, more than 80 different designations have been allocated, distinguishable through the application of prefix or suffix letters. Illustrated with over 160 images, this book, the first of two, will detail those aircraft with an aerial refueling designation, ground trainers, export and civilian tankers, and those that were used to conduct tests and evaluations.
