Fire Control Systems

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

Installed by late 1914, these ships appear to have had a single transmitter with all-around training, addressing the fore and aft turrets as receiving stations[2].

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[3].

Directors

These ships never received directors for main or secondary batteries[4].

Torpedo Control

Transmitting Stations

These ships had fore and aft TSs[5].

A C.O.S. allowed control options of

  1. Fore
  2. After
  3. Separate

Each group had Barr and Stroud Mark II 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].

Miscellaneous

By late 1914, these ships were equipped with range, orders and deflection circuits, with those in Africa, Britannia, Dominion and Hibernia being Vickers, Son and Maxim with Barr and Stroud rate instruments and those in Commonwealth, Hindustan, King Edward VII and Zealandia being Barr and Stroud Mark II[8].

These ships lacked Target Visible and Gun Ready signals[9].
