rdfs:label	Iron Duke class
rdfs:comment	This class of four ships was the third class of super-dreadnoughts to enter service and the Royal Navy, the lead ship of which is now the flag ship of the Grand Fleet. They retain the 13.5" main battery of the Orion class and share many characteristics with the preceding super-dreadnoughts. One major step forward, however, is the upgrade of the secondary batteries from the light 4" to the heavier 6" guns. They entered fleet service between 1912 and 1914.
