Jane's provide technical specifications for warships both in service and about to enter service. Highly illustrated with photographs and line drawings the guide emphasises key recognition points.
I read this book after my friend Jim mentioned Jane's fighting ships books to me and I couldn't afford them nor could I find anything on them so I went to the store picked up this one instead. Complete with a picture of the ship, tells you what country they are from and etc. If you really want to know your military ships better this is the book to do it.
