| Entry Text: | FRIEDMAN, Norman. British Submarines in Two World Wars. 432p., bibliog., illus., index. Barnsley: Seaforth; Annapolis: Naval Institute Press, 2019. ISBN: 9781526738165. Another excellent study from this major author. There are two introductory chapters on RN submarine organization and the basics of propulsion and hull structure, but the focus is on submarine design and development. Profusely illustrated with excellent plans and drawings, there is also a large number of appendices on everything from wireless telegraphy to midget submarines. |
