"Dreadnought" was the sixth ship of the RN to bear the name. To meet Admiral Fisher's goal of building the ship in a single year, material was stockpiled in advance and a great deal of prefabrication was done from May 1905 onwards with approximately 6,000 man weeks of work expended before she was formally laid down on 2 October 1905 on No.5 Slip. In addition, she was built at HM Dockyard, Portsmouth which was regarded as the fastest-building shipyard in the world. The slip was screened from prying eyes and attempts made to indicate that the design was no different to other battleships.
