Armament
During the war, along with those of other older ships, the four 6-inch guns casemated on the main deck proved of little use in practical sea states. The two forward-most main deck guns were never even fitted as their issues were glaring. Two lower casemates aft were vacated and their guns put in spray shields on the upper deck abaft the 7.5-in turrets, sacrificing 3-pdr guns that were then in the way.[1][Fact Check]
Main Battery
The 7.5-in guns were Mark I on Mark I mountings.[2]
Secondary Battery
The 6-in guns were Mark VII, on P III, P III*, P III S and/or P IV mountings. The sights were similar to those in Albemarle and Cornwall, but sturdier. Range gearing constant was 51.41 with one knot of deflection being 2.77 arc minutes. Range dials were provided for 2730 fps, 1970 fps, 3-pdr sub-caliber, 1-in aiming rifle and .303-in aiming rifle. MV correction by adjustable pointer for +/- 50 fps. Deflection dial graduated for 2730 fps at 3000 yards. Drift correction by inclining the sight 1.5 degrees. The sights were 14.45 inches above the bore and 13.1 inches to the side.[3]
Other Guns
Torpedoes
Fire Control
Rangefinders
Evershed Bearing Indicators
It is unlikely that this equipment was ever provided.[Inference]
Directors
These ships never received directors for main or secondary batteries.[4]
Gunnery Control
Local Control in Turrets
Transmitting Stations
Dreyer Table
These ships never received Dreyer tables.[5]
Fire Control Instruments
By 1909, all 6 ships were equipped with Vickers, Son and Maxim instruments for range, deflection and orders and with Barr and Stroud rate instruments as follows:[6]
- Vickers range transmitters: 6
- Vickers deflection transmitters: 6
- Vickers combined range and deflection receivers: 21
- Vickers C.O.S.: 3
- Vickers Check fire switches: 6
- Barr and Stroud rate transmitters: 4
- Barr and Stroud rate receivers: 8
- Siemens turret fire gongs: 8 with 4 keys
- Vickers fire gongs: 6 with 2 keys
- Captain's Cease Fire Bells: 12 with 1 key (supplier not stated)
These ships lacked Target Visible and Gun Ready signals.[7]
