Construction
Career
From April, 1907 to May, 1912 Dreadnought served as flagship of the Royal Navy's Home Fleet, at which point she was relieved by HMS Neptune. On 5 August, 1907 HM King Edward VII with a number of other members of the Royal Family visited Dreadnought at Spithead. Accompanied by the Board of Admiralty, as well as the commander of the Home Fleet Vice-Admiral Francis Bridgeman, the Dreadnought went for a cruise flying the royal standard. For this the captain, Reginald Bacon, was appointed CVO and Bridgeman promoted KCVO by the king.
Bloomsbury Hoax
On 10 February, 1910 she attracted the attention of notorious hoaxer Horace de Vere Cole, who persuaded the Royal Navy to arrange for a party of Abyssinian royals to be given a tour of a ship at Weymouth. In reality, the "Abyssinian royals" were some of Cole's friends in blackface and disguise, including a young Virginia Woolf and her Bloomsbury Group friends; it became known as the Dreadnought hoax. Cole had picked Dreadnought because she was at that time the most prominent and visible symbol of Britain's naval might.
Pre war
On 27 July, 1910, soon after ascending to the throne, HM King George V visited Dreadnought at Torbay. For two days Dreadnought, under the command of Captain Herbert Richmond in company with the Commander-in-Chief William May went to sea on exercises.

Rangefinders | |
Period | RFs |
---|---|
1906-1912: | FQ2 on MP2 mounting in fore top FQ2 on MP2 mounting on signal tower |

1915-1918: | FQ2 on Argo mounting in fore top 5 FT8s on MG3s in the turrets FQ2 on MN1 on compass platform |
1915-1918: | FQ2 on Argo mounting in fore top FT24 on MG3 in 'A' turrets 4 FT8s on MG3s in other turrets FQ2 on MN1 on compass platform |
Directors
Main Battery
Dreadnought was completed without a director[8], but by mid 1916 was fitted with a tripod-type director in a light aloft tower on the fore top along with a directing gun in Y turret[9][10]. The battery was not divisible into for split director firing[11].
Secondary Battery
The 12-pdrs never had directors installed[12].
Control was exercised from either the spotting or main top, with the control officer in the top communicating via navyphone to the sightsetters of his assigned groups of 12-pdrs who wore telaupads[13].
Torpedo Control
Transmitting Stations
Dreyer Table
Dreadnought was retro-fitted around mid 1916[14] with a Mark I Dreyer table[15], but was never given Dreyer Turret Control Tables[16].
Miscellaneous
Dreadnought was fitted with Evershed Bearing Indicators in fore top between in extended work between a stop in Portsmouth 9 August, 1913 and one in Gibraltar, 2 April, 1914.
9-foot rangefinders in armoured hoods were added to all 5 turrets, tied to the T.S.s by range transmitters and receivers.
