Emerald Class Cruiser (1920)
The two light cruisers of the Emerald Class were completed in 1926. A third vessel, Euphrates, was not completed.
Armament
Guns
Seven 6-in guns, 5 on the centre-line and a tandem pair of single mounts forward, had a maximum elevation of 30 degrees.[1][2]
Torpedoes
Fire Control
Range Dials
As of 1920, both ships had a Range Dial Type C with a 10 foot dial.[3]
Rangefinders
Evershed Bearing Indicators
These ships almost certainly had Evershed gear for gun control from delivery, and would also feature Evershed installations for searchlight control after orders for such installations from February 1917.[4]
Gunnery Control
Control Positions
Control Groups
Directors
All ships were completed with gunnery directors in place.[5]
The director was likely on a pedestal mounting in a tower on the foremast. 'X' or 'Y' may have served as a directing gun in addition.[6]
Transmitting Stations
Dreyer Table
In 1930, they are noted as possessing a Dreyer Table Mark III*,[7] presumably installed upon completion.
