Fire Control Systems
The general system of wiring between the TSes 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]
Gunnery Control
The ship's guns were organized in 3 groups:[3]
- Two 12-in turrets
- Starboard 9.2-in turrets
- Port 9.2-in turrets
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]
Directors
These ships never received directors for main or secondary batteries.[5]
Torpedo Control
Transmitting Stations
These ships had fore and aft TSes.[6]
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."[7]
Dreyer Table
These ships never received Dreyer tables.[8]
Shipwide Network
By late 1909, these ships were equipped with Barr and Stroud Mark II equipment for range, orders and deflection.[9]
The Handbook for Fire Control Instruments, 1909 lists the Barr and Stroud Mark II equipment on this class as:[10]
- Combined Range, Order, Deflection: 8 transmitters, 32 receivers
- Group Switches: 4
- Rate: 4 transmitters, 12 receivers
Additionally, this class had the following Graham fire control equipment:[11]
- Turret fire gongs: 22 with 8 keys (pushes in lamp box; 16 keys in Lord Nelson)
- Fire Gongs: none
- Captain's Cease Fire Bells: 14 with 1 key
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 TSes and control positions.[12]
