The five light cruisers of the Ceres Class were completed in 1917 and 1918.
Armament
The ships were armed as follows.[1]
Guns
- Five 6-in 45cal BL Mark XII guns on the centre-line with a maximum elevation of 30 degrees.[2]
- Two 3-in 20cwt QF on HA mountings
- Four 3-pdr
- Two 2-pdr pom-poms
Torpedoes
- Eight 21-in above water tubes on four twin mountings disposed in pairs abreast
Fire Control
Rangefinders
Sometime during or after 1917, an additional 9-foot rangefinder was to be added specifically to augment torpedo control.[3]
Evershed Bearing Indicators
These ships almost certainly had Evershed gear for gun control from delivery, as they followed the Centaur class.[4]
Orders for Evershed installations for searchlight control from February 1917 applied to the Danae class, but may not have applied to Ceres.[5]
Gunnery Control
Control Positions
Control Groups
Directors
All ships were completed with gunnery directors in place.[6] The director was in a tower on a pedestal mounting..[7] It is not known if 'X' or any other gun acted as a directing gun as in the earlier Caledon class.[8]
Transmitting Stations
Dreyer Table
These ships had no fire control tables.[9]
Fire Control Instruments
[TO BE CONTINUED - TONE]
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. [10]
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 Ceres class) was to receive Chadburn Torpedo Telegraphs to meet this need. Otherwise, Barr and Stroud would be a likely choice.[11]
