Such a publication has never existed before - neither here in Russia, nor in the West! The maximum that you will find abroad are separate books on German and British cruisers of the First World War. But you cannot buy a complete illustrated encyclopedia, which presents information about all ships of this class without exception from seventeen countries that participated in the Great War, either in European or American bookstores or online stores. This book is the first. A colossal amount of information about cruising forces is not only great naval powers - Great Britain, Germany, France, Russia, Italy, Japan - but also the secondary fleets of Austria-Hungary, Brazil, Turkey, China, Portugal, Greece, Peru, Uruguay, Romania and even Persia! All about performance characteristics, service and combat use of 392 cruisers of the First World War, 69 of which were lost.
