Construction
Before construction of Dreadnought began extraordinary steps had been taken to ensure a swift delivery time. The hull structure had been designed to be as simple as possible while being able to withstand the shock of firing a broadside of eight guns. The variety of types of steel size was kept to a minimum and where possible the size of armour plating, in its various thicknesses, was standardised. As much materiel as possible was ordered in quantity and stockpiled in advance. By the time construction began, £12,217 had been spent on labour; £29,078 had been spent on materiel and 1,100 men had been engaged.[2]
Armament
The BVIII mounting was designed by Vickers and tendered in July, 1905. "X" and "Y" mountings were built by Vickers at a cost of £69,860 per mounting. Armstrong constructed "A", "P" and "Q" mountings, at a tendered cost of £70,092.[3]
Career
Captain Archibald G. H. W. Moore succeeded Captain Madden on 1 December, 1908.[4]
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.
War service
On 19 March 1915, Dreadnought was part of the Fourth Battle Squadron and under the command of Captain Alderson when she rammed and sank U.29, which had fired torpedoes at the ships as they steamed back to Cromarty.[5]

Directors
Main Battery
Dreadnought was completed without a director but by mid 1916 was fitted with a geared tripod-type director in a light aloft tower on the fore top along with a directing gun in 'Y' turret.[10][8] The battery was not divisible into groups 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[8].
Torpedo Control
Transmitting Stations
Dreyer Table
Dreadnought was retro-fitted around mid 1916[13] with a Mark I Dreyer Table, but was never given Dreyer Turret Control Tables[14].
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.
