Lord Nelson Class Battleship (1906)
Contents
Fire Control Systems
The general system of wiring between the TSs is illustrated in Handbook for Fire Control Instruments, 1914[1].
Rangefinders
Evershed Bearing Indicators
Installed by late 1914, these ship appear to have had but 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
- Fore
- After
- Separate
Each control 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 Barr and Stroud Mark II equipment for range, orders and deflection[8].
This was the first battleship class in the Royal Navy to have 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[9].
