The author, an expert on WWI aviation and a prolific writer for Osprey, has produced a superb. well-written and interesting book about ... naval aviation activities [of Germany, Austria-Hungary, Russia, Italy, Greece and the United States].

Part 1 mainly focuses on Britiain's Royal Naval Air Service (RNAS), while Part 2 covers the remainder, including Germany, Russia, Austria-Hungary, Italy and Greece ... These new additions to the 'Aircraft of the Aces' series will offer enthusiasts and modelers a wide range of types and markings for future projects, Having watched Osprey's growing list of such works for more than 16 years, I can say that these two books are packed with the most fascinating details I have yet seen.

Peter B. Mersky, Aviation History (November 2012)

Guttman's books illuminate a littleknown portion of First World War aviation history. With the exception of Raymond Collishaw and perhaps one or two other aces, the naval aces of the Great War have taken a deep back seat to their colleagues in other air services. Thus, the need for a study of First World War naval aces is evident and has been well fulfilled by these works. The novice to this subject will find these books to be a valuable introduction, while the expert will consider them an excellent resource.
