Fire Control
Rangefinders
Evershed Bearing Indicators
All 5 units were likely fitted with this equipment before late 1914.[Inference][1]
Details likely resembled those for the King George V class.
Gunnery Control
The control arrangements were almost certainly developed along lines similar to the King George V class, outlined here as follows.[Inference]
Control Positions
- Gunnery control tower
- 'B' turret
- 'X' turret
Control Groups
The four 15-in turrets were each a separate group with a local C.O.S. so that it could be connected to
- Transmitting Station
- Local control from officer's position within turret
The 6-in guns were probably divided into 2 broadside groups, port and starboard.
Directors
Main Battery
These ships were fitted with 2 cam-type tripod-mounted directors, one in an armoured tower and one in a light aloft tower,[2] as well as a directing gun (in 'X' turret?).[3]
The main battery was divisible into two groups, fore ('A' & 'B') and aft ('X' & 'Y').[4] A C.O.S. in the TS offered the following options:[5]
- All guns on aloft director
- All guns on armoured director
- All guns on directing gun
- Forward group on aloft director, aft group on armoured director
- Forward group on armoured director, aft group on directing gun
Each gun had a local C.O.S. with 3 positions:
- Gunlayer's firing (local trigger circuits connected)
- Director 1 (director main to local main, director aux to local aux)
- Director 2 (director main to local aux, director aux to local main)
Secondary Battery
All units except Queen Elizabeth had a pair of pedestal-mounted directors for their secondary batteries. Queen Elizabeth's 6-in guns were supported by a pair of tripod-mounted directors.[6]
The secondary directors were situated port and starboard high on her forward superstructure.[7] The broadside-mounted secondary guns were in port and starboard groups, and either were laid and fired locally or under the control of the director on their side.
Torpedo Control
Transmitting Stations
Following evolutionary lines of development which were firming up in the King George V class, these ships probably had a TS for the main battery (with a Dreyer Table), and one for the 6-in guns (likely without a Dreyer table, or just a Turret Control Table).[Inference]
Dreyer Table
Each ships had a Mark IV* Dreyer Table, although it is possible that Queen Elizabeth was originally given a Mark IV Dreyer Table which was later upgraded to the Mark IV* standard.[8]
Each ship also had 4[Inference] Dreyer Turret Control Tables.[9]
Fire Control Instruments
Continuing the pattern established in the Colossus class, all 5 units used Vickers F.T.P. Mark III range and deflection instruments to the gun sights and Barr and Stroud (probably Mark II*[Inference]) instruments for other purposes.[10]
The ships also had Gun Ready signals in the TS and control positions, but had no Target Visible signals.[11]
