Armament

Torpedoes

Originally, there were five above-water and two submerged 18-in tubes:[1][2]

  • four above-water fixed broadside tubes at corners of armoured citadel, two at 50 degrees abaft the beam, and two at 42 degrees ahead, all horizontal.
  • one above water fixed tube astern, horizontal.
  • two submerged broadside forward, depressed 1 degree and angled directly abeam; axis of tube was 9 foot 5 inches below load water line and 2 foot 4 inches above the deck.

By 1909, the above water tubes had all been removed.

Fire Control

Though it may have little relevance given the age difference, the general system of wiring between the TSes in ships prior to Lord Nelson class is illustrated in Handbook for Fire Control Instruments, 1914[3].

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[4].

Gunnery Control

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[5].

Transmitting Stations

Dreyer Table

These ships never received Dreyer tables[6].

Fire Control Instruments

In 1906, it was planned to equip Centurion with Siemens Mark II equipment throughout, but she is absent from a list of ships so equipped in a 1914 source.[7][8] No reference to similar plans for Barfleur have been located.
