The two light cruisers of the Centaur Class were completed in 1916.

Machinery

Generators

In 1916, it was stated that ""C" and "D" class light cruisers" have three 52.5 kw dynamos at 105 volts.[1]

Armament

The ships were armed as follows.[2]

Guns

  • Five 6-in 45cal BL Mark XII guns on the centre-line with a maximum elevation of 30 degrees.[3] The guns had armoured shields of 1/4 inch on the face, 3/16 inch on sides and top, weighing 1.25 tons.[4]
  • Two 3-in 20cwt QF on HA mountings
  • One 13-pdr

Torpedoes

  • Two Service Bar 21-in submerged broadside tubes amidships depressed 4 degrees and bearing 90.[5]

These were to be the last Royal Navy light cruisers to feature submerged torpedo tubes.

Fire Control

Navyphones

Navyphones[6]

Each gun had a Pattern 3333 Navyphone and a set of Telaupads.

[TO BE CONTINUED - TONE] ARTS 1916, Plate 78.

Rangefinders

Evershed Bearing Indicators

This class was the first light cruiser class to feature Evershed installations, possibly upon their very completion. Such equipment became standard from here on out.[7]

Gunnery Control

Control Positions

There was a fore control position, an aft control position, and a control top.

Control Groups

There were three control groups:[8]

  1. No. 1 gun
  2. Guns Nos. 2 & 3
  3. Guns Nos. 4 & 5

Directors

Director Firing Circuitry[9]

Both were completed with gunnery directors in place.[10]

The director was in a tower on a pedestal mounting and was augmented by use of the #4 gun as a directing gun.[11]

The COS had 3 positions:

  1. director tower to all guns
  2. directing gun to all guns
  3. director tower to guns 1-3, directing gun to guns 4 & 5

Each gun had a COS to connect it to director or local firing circuits. The gun director tower had a 2-way switch to connect the night sights and such to either main or auxiliary power fed through a 5-way box.[12]

Transmitting Stations

The ships had a TS.[13]

Dreyer Table

These ships had no fire control tables.[14]

Fire Control Instruments

Torpedo Control

In 1916, it was decided that all light cruisers of Bristol class and later should have torpedo firing keys (Pattern 2333) fitted on the fore bridge, in parallel with those in the CT, and that a flexible voice pipe be fitted between these positions. [15]

Additionally, all light cruisers with submerged tubes were to receive torpedo order and gyro angle instruments between torpedo flats and both control positions. The C class (which may or may not encompass the Centaur class) was to receive Chadburn Torpedo Telegraphs to meet this need. Otherwise, Barr and Stroud would be a likely choice.[16]

Rangefinders

Sometime during or after 1917, an additional 9-foot rangefinder being handed down from a battleship or battlecruiser (likely an F.T. 24) was to be added specifically to augment torpedo control.[17]
