This is the 21st volume in Osprey’s “Air Vanguard” series. A quick look at Osprey’s website shows this is scheduled for an August, 2015 publication date.
The “Air Vanguard” series seems geared to providing an overall view of the subject aircraft’s development, technical specifications, and operational history. All other titles in this series have been available in various “eReader” formats (at a slightly lower price than the print version), so I imagine upon release that this will be the case for this volume. A glance at the publishing information in the book shows different ISBN numbers for the PDF/EPub editions, seeming to confirm this fact.
The book is broken down into 4 basic sections: Design and Development, Technical Specifications, Mark by Mark, and Operational History. A brief ‘Conclusion’ section wraps things up, and a decent bibliography for further reading is included.
