Fire Control

Though it may have little relevance given the age difference, the general system of wiring between the TSs in ships prior to Lord Nelson class is illustrated in Handbook for Fire Control Instruments, 1914[1].

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[2].

Gunnery Control

The ship's guns were organized in 3 control groups[3]:

  1. Two 12-in turrets
  2. Starboard 6-in guns ('A' & 'X')
  3. Port 6-in guns ('B' & 'Y')

Local Control in Turrets

There was no provision in these ships for local turret control wherein the receivers in the turret could be driven by transmitters in the officer's position at the back of the turret[4].

Transmitting Stations

These ships likely had fore and aft TSs[5][Inference].

A C.O.S. allowed[Inference] control options of

  1. Fore
  2. After
  3. Separate

Each control group had transmitters with a pair of receivers, one wired directly to the transmitter as a tell-tale, and the other fed off the wires going to the distant guns (i.e., the aft guns for the fore TS and vice-versa) as a repeat. "These repeat receivers are necessary to keep the idle transmitters in step; when changing back from separate control they are required to enable both halves of the group to be set alike before being paralleled on to one transmitter."[6]

Dreyer Table

These ships never received Dreyer tables[7].

Shipwide Network

By late 1914, all were equipped with Siemens Mark I instruments for range, orders and deflection, except Glory which had Siemens Mark II equipment throughout.[8][9]

These ships lacked Target Visible and Gun Ready signals.[10]

Torpedo Control
