The two light cruisers of the Birkenhead Class were completed in 1915 and 1916.

Armament

Guns

Torpedoes

2 Elswick 6.8m 21-in submerged broadside tubes forward depressed 2 degrees and bearing 90. Impulse from Elswick H.P. air.[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

Both were fitted with directors in 1917 and 1918.[4]

The director was on a pedestal mounting in a tower on the foremast. Likely, 'X' or 'Y' served as a directing gun.[5]

Torpedo Control

Transmitting Stations

Dreyer Table

These ships had no fire control tables.[6]
