The six light cruisers of the Caroline Class were completed in 1914 and 1915.
Armament
Guns
These ships were originally armed with a mixed battery of 2x6-in guns aft and 8x4-in guns. Later, in stages, 2 more 6-in guns were shipped, replacing 4-in guns. Most of the 6-in mountings were simultaneously modified to a 20 degree elevation limit, increased from a likely former limit of 15 degrees.[1]
Torpedoes
Fire Control
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.[2]
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.[3]
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.[4]
Gunnery Control
Control Positions
Control Groups
Directors
All six ships were fitted with directors in 1917 and 1918.[5]
The director was on a pedestal mounting without a tower. Likely, there was no directing gun.[6]
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 Caroline herself, or when they were effected.[7]
Torpedo Control
Transmitting Stations
Dreyer Table
Most of these ships had no fire control tables during the war, but by 1918, Comus and Carysfort are listed as having Dreyer Turret Control Tables in their T.S.es, and by 1930 all but Caroline and Cordelia were so equipped.[8]
