Conway's All the World's Fighting Ships: 1906-1921 Hardcover – January 1, 1985

an excellent book in an excellent series, most complete, all the technical details you could ask for and many good drawings and photo's

Out of print gem. Although a bit pricey, it's worth it if you have any interest in the subject matter. Well researched summaries of all the warships of the period in the principal naval powers. More narrative and analysis than in the Jane's Warships of WWI. But then it is much more expensive on the used book market. If you can afford it, worth acquiring.

This is a technical data collection that can answer any question you might have about ships of the period.

Excellent book
