This is a compilation which brings together in one volume technical descriptions of the Royal Navy's Nelson Class battleships. The Nelson class comprised just two battleships (the Nelson and Rodney), built shortly after, and under the terms of, the Washington Naval Treaty of 1922. They were the only British battleships built between the Revenge class (ordered in 1913) and the King George V class, ordered in 1936. They served extensively in the Atlantic, Mediterranean and Indian oceans during World War II. The Rodney was made famous by her role in the sinking of the German battleship Bismarck in May 1941. The author describes their technical aspects, precisely describing the differences between them. Both ships are described and illustrated with full technical specifications.
