Twenty-First Century Military Helicopters

Rating:
Summary: Disappointing
Review: Having bought this book and hoping to receive a well written and illustrated overview of all current military helicopters, I was disappointed to find a lot of errors in this book.
Some examples: page 47, AH-1J sea cobra shows the picture of a AH-1S (now F), page 69 Denel Oryx shows a Puma picture, page 70 shows a AH-1S (F) and is titled AH-1W super Cobra. Also in the text there are some errors (in the specs of the UH-1N it is stated this a/c has a T53-L13B engine). A lot of types are described multiple times but under different manufacturer names / countries. Some types currently in service are omitted and types out of service are described.
All in all fairly disappointing for an author who is a former member of the British Intelligence services. My advice: don't buy this book and if these books are printed have them final-read by somebody who knows his/her helicopter types
