==Binoculars==
In September 1914, the ships were allowed four additional pairs of Pattern 343 Service Binoculars.{{AWO1914|331 of 8 Sep, 1914}}

==Structure==
In July 1914, the ships' captains were asked to describe the materials and costs required to enlarge the upper bridge.{{AWO1914|85 of 3 July, 1914}}

==Armament==
In early 1913, new pattern G. 329 trainer's telescopes of 2.5 power and 20 degree field were issued to these and many other capital ships, to replace the 5/12, 5/15 and 5/21 variable power G.S. telescopes that had previously been in use.<ref>Admiralty Weekly Orders.  28 Feb, 1913.  {{TNA|ADM 182/4}}.</ref>

During the war, along with those of other older ships, the ten 6-inch guns casemated on the main deck proved of little use in practical sea states.  It was decided to remove them, plate their ports over and move eight of them to the upper deck, with three each side between the 9.2-in turrets, and one each side on the forecastle.  Low freeboard gave them marginal value even in the new locations.{{UKTHVol4Part36|p. 9}}

===Main Battery===
The six 9.2-in guns were Mark X, mounted in Mark V S single mountings.{{TheSightM|p. 110}}

The centre line turrets were designated fore and aft, those to starboard "A" and "X" and those to port "B" and "Y".<ref>''Manual of Gunnery in H.M. Fleet (Volume I), 1907'', p. 2.</ref>

===Secondary Battery===
The original ten 6-in guns were Mark VII, probably mounted on P. III or P. IV mountings.{{TheSightM|p. 111}}  They were numbered 1-5 on port and starboard<ref>''Manual of Gunnery in H.M. Fleet (Volume I), 1907'', p. 2.</ref>

Later, and seemingly before Jutland, two were removed and all remaining guns relocated to the upper deck.  Even in the new positions, the low freeboard of these ships gave the guns limited value.

In February, 1913, these mountings, along with many other 4-in and 6-in mountings in various capital ships and cruisers were to have illumination added for their training index racers.<ref>Admiralty Weekly Orders. {{TNA|ADM 182/4}}.  21 Feb, 1913 entries.  pp. 3-4.</ref>

===Torpedoes===
In 1909, as heater torpedo supplies were still growing, these ships were to receive two [[18-in Fiume Mark III** H. Torpedo]]es each.{{ARTS1909|p. 14}}

In 1913, it was approved, as part of a general reallocation of 18-in torpedoes, to replace the torpedoes on [[Minotaur Class Cruiser (1906)|''Minotaur'' class]] (except ''Shannon''), [[Duke of Edinburgh Class Cruiser (1904)|''Duke of Edinburgh'']] and [[Bristol Class Cruiser (1909)|''Bristol'' classes]] with Fiume Mark III**  torpedoes.{{ARTS1913|p. 8}}

In early 1914, the ships had two [[Torpedo Director Pattern 2006]]s and were to have them exchanged for -A models which supported gyro angling.{{AWO1914|1019 of 17 Apr, 1914}}

==Fire Control==

===Rangefinders===

===Evershed Bearing Indicators===
It is unlikely that this equipment was ever provided.{{INF}}

===Directors===
In 1916, it was approved that the ships of this class should be retrofitted with directors as time, resources and opportunity permitted,{{ARTS1916|p. 175}} but these plans were slow to execute.  This intention was reiterated in 1917.{{ARTS1917|p. 229}}  {{UK-DukeOfEdinburgh}} received one in October 1918, but {{UK-BlackPrince}} was likely lost before her equipment was ever ordered.{{FCHMShips|p. 15}}{{INF}}

''Duke of Edinburgh'''s [[Elevation Receiver]]s for her 9.2-in battery were 4-in Triple Type with mechanical tilt correctors, Pattern H. 13.  They could indicate elevations up to 15 degrees.  The [[Small Type Training Receivers]] were pattern number 20 in the fore turret and A1 and B1, whereas the after turret, A2 and B2 had pattern number 21.{{DirectorH|pp. 145, 146}}

===Gunnery Control===
<!--
===Local Control in Turrets===
-->
===Transmitting Stations===
It seems from frequent mention of a fore {{TS}} that these ships had transmitting stations fore and aft.

===Dreyer Table===
These ships never received Dreyer tables.{{DreyerH|p. 3}}

===Fire Control Instruments===
By 1909, both ships were equipped with [[Vickers|Vickers, Son and Maxim]] instruments for range, deflection and orders and with [[Barr and Stroud]] [[Range Rate|rate]] instruments as follows:{{HFCI1909|pp. 56, 60}}
* Vickers range transmitters:  10
* Vickers deflection transmitters:  10
* Vickers combined range and deflection receivers: 33
* Vickers C.O.S.: 5
* Vickers Check fire switches: 10
* Barr and Stroud rate transmitters: 4 
* Barr and Stroud rate receivers: 8
* Siemens turret fire gongs: 12 with 6 keys
* Vickers fire gongs: 10 with 4 keys 
* Captain's Cease Fire Bells:  16 (16 in {{UK-DukeOfEdinburgh}}) with 1 key (supplier not stated)

As in the [[Minotaur_Class_Cruiser_(1906)|''Minotaur'' class]], bearing instruments were installed in or by 1915.  The receivers in the four 9.2-in broadside guns and the 6-in officers' positions are operated in by transmitters in the TS for their side or by their respective master transmitters in the foretop.  The two centre-line turrets are connected to a transmitter in the {{TS}} or to one of the master transmitters.  The 6-in guns are worked om transmitters in the O.O.Q. position on that side.{{ARTS1915|p. 219. I am not fully sure I grasp this description}}
The overall bill of fare ran to:
* 2 special "master" bearing transmitters, Graham's type (in foretop, P&S)
* 6 Barr and Stroud bearing transmitters: 
** 2 in the O.O.Q.'s position, P & S
** 2 in the foretop, P & S
** 2 in the {{TS}}, P & S
* 23 Barr and Stroud bearing receivers:
** 10 for the 6-in guns (1 each)
** 6 for the 9.2-in guns (1 per turret)
** 2 in the O.O.Q.'s position, P & S
** 1 repeat in the fore {{TS}}
** 2 repeats in the foretop
* Three C.O.S. (one in fore {{TS}}, and two in foretop)

These ships lacked ''Target Visible'' and ''Gun Ready'' signals.{{HFCI1914|p. 11}}
