Fire Control Systems

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

Dreyer Table

As of 1917, Inflexible still carried the Mark I Dreyer tables she'd been outfitted with[8]. 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[9].

The ships were never given Dreyer Turret Control Tables[10].

Shipwide Network

By late 1914, these ships were equipped with Barr and Stroud Mark II equipment for range, orders and deflection[11].

The ships also had Target Visible and 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[12].
