Cambrian Class Cruiser (1915)
The four light cruisers of the Cambrian Class were completed in 1915 and 1916. They were sometimes considered repeats of the earlier two-ship Calliope class.
Armament
Guns
Torpedoes
2 Service Bar 21-in submerged broadside tubes amidships depressed 4 degrees and bearing 90.[1]
Fire Control
Rangefinders
Evershed Bearing Indicators
The Centaur class were the first light cruisers fitted with Evershed gear for gun control, but it is not clear whether older light cruisers were ever fitted.[2]
Orders for Evershed installations for searchlight control from February 1917 first applied to the Danae class, but seem unlikely to have applied to earlier ships.[3]
Gunnery Control
Control Positions
Control Groups
Directors
All four were fitted with directors in 1917 and 1918.[4]
The director was on a pedestal mounting without a tower. Likely, there was no directing gun.[5]
The elevation limits of their weapons may have increased in late 1917 or early 1918, resulting in orders for adapting their director systems issued 13 November, 1917. It is not clear whether these alterations were for the entire class or just Cambrian herself, or when they were effected.[6]
Torpedo Control
Transmitting Stations
Dreyer Table
These ships had no fire control tables.[7]
