Fire Control
Rangefinders
Evershed Bearing Indicators
All 4 units were likely fitted with this equipment before late 1914[1].
The transmitting positions were
- Conning Tower (transmitters to port and starboard with C.O.S. to select one in use)
- Gunnery control tower
- 'B' turret
- 'X' turret
The protocols for handling wooding of the turrets is outlined in the Handbook for Fire Control Instruments, 1914[2].
Gunnery Control
The control arrangements were as follows[3].
Control Positions
- Gunnery control tower
- 'B' turret
- 'X' turret
Some ships had C.O.S.s within the control positions so they could be connected to either TS[4].
Control Groups
The five 13.5-in turrets were each a separate group with a local C.O.S.[Inference] so that it could be connected to
- Forward TS
- After TS
- Local control from officer's position within turret
Directors
Main Battery
The ships were fitted with a cam-type tripod-type director in a light aloft tower on the foremast along with a directing gun in 'X' turret[5].
The main battery could be divided into forward ('A', 'B' & 'Q') and aft ('X' & 'Y') groups for split director control[6].
A C.O.S. in the TS afforded these options[7]:
- all turrets on aloft tower
- all turrets on directing gun
- forward group on aloft tower, aft group on directing gun
Secondary Battery
The 4-in guns never had directors installed[8].
Torpedo Control
Transmitting Stations
These ships discarded the second TS found in earlier dreadnoughts and relied on a single TS[9].
Dreyer Table
King George V had a Mark III Dreyer table while the other three units received Mark II Dreyer tables[10][11]. As of June 1918, they had not been provided Dreyer Turret Control Tables[12].
Shipwide Network
Continuing the pattern established in the Colossus class, all 4 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[13].
The ships also had Gun Ready signals, with indications of which turret could see the target and which guns were ready being visible in the TSs and control positions, but these ships were the first to discontinue the use of Target Visible signals that appeared in earlier dreadnoughts.[14].
