Fire Control
Rangefinders
Evershed Bearing Indicators
All units were likely fitted with this equipment by late 1914[1].
The transmitting positions were
- Fore control platform (transmitters to port and starboard with a local switch to select one in use)
- 'A' turret
- 'X' turret
- Upper aft conning tower
The protocols for how her crew should handle wooding of the turrets was outlined in the Handbook for Fire Control Instruments, 1914[2].
Gunnery Control
The control arrangements were likely as follows[3].
Control Positions
- Fore top
- Main top[Inference]
- 'A' turret[Inference]
- 'Y' turret[Inference]
Some ships had C.O.S.s within the control positions so they could be connected to either TS[4].
Control Groups
The four 12-in turrets were separate groups, each 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 tripod-type director in a light aloft tower on the foremast along with a directing gun (in Y turret?)[5]. The battery was not divisible into groups for split director firing[6].
Secondary Battery
The 4-in broadside guns are not listed as ever having had directors installed[7].
Torpedo Control
Transmitting Stations
Like all large British ships of the era prior to King George V and Queen Mary, these ships had 2 TSs[8].
Dreyer Table
As of 1917, Inflexible still carried the Mark I Dreyer tables she'd been outfitted with[9]. Invincible was lost with her Mark I table at the Battle of Jutland. It appears likely that Indomitable never was fitted with a Dreyer table[10].
The ships were never given Dreyer Turret Control Tables[11].
Shipwide Network
By late 1914, these ships were equipped with Barr and Stroud Mark II equipment for range, orders and deflection[12].
The ships also had Target Visible and Gun Ready signals, indicating which turrets could see the target and which guns were ready in the TSs and control positions[13].
