The 2025 edition of Warship, the celebrated annual publication featuring original research on the history, development, and service of the world's warships. For over 45 years, Warship has been the leading annual resource on the design, development, and deployment of the world's combat ships. Featuring a broad range of articles from a select panel of distinguished international contributors, Warship combines original research, new book reviews, warship notes, an image gallery, and much more, maintaining the impressive standards of scholarship and research with which the annual has become synonymous. Detailed and accurate information is the hallmark of all the articles, which are fully supported by plans, data tables, and stunning photographs. This year's Warship includes features on France's first destroyers, the turn-of-the-century 300-tonne type; Denmark's H-class submarines of World War II; Italy's proposed battlecruiser designs; the Imperial Japanese Navy's Chikuma-class protected cruisers; Soviet S-class submarines; and the first of a two-part exploration of German destroyers of World War I.
