I found this book having very good illustrations but being otherwise rather superficial. It also contains quite a number of errors or inconsistencies, such as using the Weimar Republic flag as "header" for ships built and used by the Kaiserliche Marine; likewise for ships built during the Czarist era the national designation USSR and the Red flag are used. These points may be minor but they reflect on the vetting of the book. I also find the complete lack of line drawings making it harder to appreciate the designs of the various ships.

All in all, those wanting more detailed and reliable information on this interesting subject should look elsewhere.

An outstanding book!!!! Written very well with great pictures. Peter Hore knows his stuff!!! I highly recommend it.
