This book can be regarded as the masterpiece of William Green, but it can also be considered as a further elaboration of the German part of his earlier 'Warplanes of World War Two' and the 'Famous Fighters/Bombers of World War Two' duo. In that case I would like a 'Warplanes of the British Empire' as well, and for that sake of any other main combatant in WW2. For books about warplanes of other countries often miss the exhaustive and encyclopedic way Mr. Green has used in describing the German Aircraft of World War Two. There are detailed technical analysis, thorough histories of development, assessment of performance, beautiful line drawings and vital statistics of each and every single type of aircraft that Germany produced before and during World War II. I have yet to see a similair 672 page work about US, British, Russian, Japanese or Italian aircraft.
