For centuries the vessels of the Royal Navy have both protected Britain's shores, and made her influence felt in the wider world. The first line of defence and a powerful weapon, they are a symbol of British dominance of seas. In this comprehensive and detailed reference work, Maurice Cocker describes the Royal Navy's battleships, battlecruisers, cruisers and scouts from 1900 to the present day. Complete information is given for each class of vessel, including start date, completion and location of construction, size and weaponry, speed, complement and armour. Every ship is listed, as well as details of those vessels lost to enemy action. Complimented by over 250 technical drawings and photographs, this book is an invaluable reference tool for naval historians and enthusiasts alike.
