This in the sixth volume in Osprey’s Air Vanguard series, but the first I have come across. The series seems geared to providing an overall view of the subject aircraft’s development, technical specifications, and operational history. One interesting angle on this series is that the books are also available in eReader formats such as Kindle or ePDF files. People have differing opinions on which format is better suited to a reference book, but in any case it is nice that this option is available.
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 small bibliography (6 titles) is included.
